Introduction
SIEMENS is one of the leading manufacturers of control products. The
product range extends from devices that switch a few mA to circuit
breakers used in power distribution.
Throughout the continuing development of these products we have always
striven to ensure that requirements in terms of fundamental performance
features, electrical and mechanical service life, dimensions, and ease of
installation and maintenance are met or exceeded.
We have been able to meet the demands resulting from increased environ-
mental awareness, particularly in the last ten years or so, by developing and
using environment-friendly and recyclable materials. As a result, we have
developed modern industrial switching devices, particularly in the field of
low-voltage switchgear, that meet all the relevant demands in terms of
environment-friendliness.
Building on decades of experience, we have created a completely new
generation of circuit breakers, contactors, auxiliary contactors, overload
relays, contactor relays, time relays, and 3RW3 semiconductor motor con-
trol devices (referred to below as soft starters) under the name SIRIUS for
the large and continuously growing number of motor drives in the range up
to 250 kW (400 HP).
These new SIRIUS devices fulfill all the demands placed on them in practice
and can be used as stand-alone devices or modular components of com-
plete load feeders, or integrated in low-voltage distribution cabinets or low-
voltage switching stations.

1.1 Specifications/regulations/approvals
ALPHA/LOVAG The Low Voltage Controls and Distribution Division of Siemens AG is a
member of "Gesellschaft zur Prüfung und Zertifizierung von Niederspan-
nungsgeräten e.V. ALPHA" (Society for Testing and Certification of Low-
Voltage Equipment), Frankfurt am Main.
The responsibility of manufacturers and the high quality of products are pro-
moted by ALPHA by means of supportive procedural guidelines for testing
equipment in accordance with the currently valid standards. Providing spe-
cific conditions are fulfilled, ALPHA can also issue officially recognized
product certificates if required. As a member of LOVAG, ALPHA is also
working towards obtaining international recognition for declarations of con-
formity and certificates.
In LOVAG (Low Voltage Agreement Group), international specialists from
certification bodies and industry are working together to create a
standardized European certificate.

Explosion protection Motor protection devices that protect a motor installed in a potentially
explosive atmosphere against overloading must comply with certain special
requirements. These requirements are laid down in the following standards:
• EN 60947-1
• EN 60079-14
• EN 60947-4-1
•EN 50014
• EN 50019.
Certification
On July 1, 2003 a new era began in the area of explosion protection. Since
this date, within the European Union, only those devices and protection sys-
tems that have been certified for use in potentially explosive atmospheres in
accordance with directive 94/9/EU can be brought into circulation.
Only those motor protection devices that have been constructed in accor-
dance with the above-mentioned standards and which have a conformity
declaration from the manufacturer based on a prototype test certificate are
permitted to be brought into circulation within the member states of the EU.
The quality management system of the manufacturer is also subjected to
certain requirements and a "QM certificate" must be obtained for the manu-
facturer from a recognized authority.

SIRIUS System Manual
1-4 A5E40534713002A/RS-AA/001
Certification of the QM system
A certificate of approval for quality assurance production has been issued by
DMT 1) with the DMT 1) number 02 ATEX ZQS/EM, in accordance with
directive 94/9/EU.
This certificate is valid for equipment groups I and II and categories M2
and 2: Safety and control devices for electrical equipment.
Certificates
For the 3RV, 3RU, 3RB, 3UF5 and 3RN motor protection devices, the
corresponding conformity declarations and prototype test certificates for
Category 2G and partly 2D are available and can be supplied on request.
Identifying markings
All equipment must be marked in accordance with the ATEX guideline. The
ATEX identification code contains the equipment group, the approved envi-
ronment, the number of the certification authority and other technical data
that was determined from the type test.
UL/CSA Underwriter’s Laboratories (UL) and the Canadian Standards Association
(CSA) are authorized to grant approvals acording to US or Canadian regula-
tions and standards. These standards typically apply to the control product
as a componient and not the installation or the use of the product. It is the
responsibility of the end user of the control product to make sure each
installation complies with all of the applicable safety requirements, laws,
regulations, codes and standards (examples: N.E.C., the C.E.C. and OSHA
regulations.
1)DMT
The certification authority of the Deutschen Montan Technologie GmbH,
numbered as authority number 0158 in accordance with Article 9 of Direc-
tive 94/9/EU of the European Parliament dated March 23, 1994, certifies
that Siemens Amberg and Cham maintains a quality system for produc-
tion that satisfies Appendix IV of this directive.

1.2 Product range
SIRIUS system The SIRIUS product range consists of 3RV circuit breakers/Motor Starter
Protectors, 3RT contactors, 3RH/3RT control relays and auxiliary contacts,
3RU thermal overload relays, 3RB10/3RB12 electronic overload relays, 3RP
time relays, 3RW3 semiconductor motor control devices (referred to below
as soft starters), and combinations of these devices, which form the 3RA
load feeders (combination starters).
The individual devices are developed and built in such a way that it is very
easy to put them together to make load feeders. This is possible because
the devices are all built to work together on both an electrical and a
mechanical level.

1.3 System features
The entire SIRIUS range of devices is divided up into only four frame sizes
(S00 to 5.5 kW (7.5 HP), S0 to 11 kW (15 HP), S2 to 22 kW (40 HP), S3 to
45 kW (75 HP) at 400 V) with three different frame widths (45 mm for S00
and S0, 55 mm for S2 and 70 mm for S3) and has a uniform range of acces-
sories for all frame sizes.
Modular system The individual components of the SIRIUS range are building blocks in a
modular system that are harmonized in terms of both their frame size and
their technical specifications. This ensures that individual requirements can
be met quickly and cost-effectively.
Uniformity The devices are harmonized with regard to their ratings and their technical
specifications:
• The same width ensures rapid installation.
• The terminal systems are standardized, and devices with the same rated
current have the same terminals.
Performance capability All SIRIUS devices can be mounted side by side without derating in an
ambient air temperature of up to 60 °C.
Accessories All accessories, such as the auxiliary switches and surge suppressors, can
be mounted and removed without tools.
You can use link modules that connect devices both mechanically and elec-
trically to put together combinations of devices and build fuseless load
feeders.
Communication The interface of SIRIUS-control components with a high level control sys-
tem is in addition to the conventional wiring is possible over networking
systems:
• AS-Interface
•PROFIBUS-DP
Using these networking systems SIRIUS-control components are incorpo-
rated in the SIEMENS automation concept Totally Integrated Automation.
Totally Integrated Automation offers the user threeway continuity in planing/
programing, data management and communication.
Safety technology SIRIUS-control components are often used in safety related installations.
With the Safety Integrated-concept, solutions ranging from safety relays up
to fail safe communication over AS-Interface or PROFIBUS-DP can be
achieved.

• Soft starters: No screw-type panel mounting
Snap-on mounting
(DIN rail mounting)
The SIRIUS switching devices are snapped onto 35 mm DIN rails in acc.
with DIN EN 50 022 without a tool.
The devices with a frame size of S3 require a rail with an installation height
of 15 mm. Alternatively, they can also be snapped onto 75 mm rails.

1.5.2 Screw-type terminals
The terminals used do not vary within a frame size. The current switched by
the different devices of a single frame size does not vary either. This means
you can use the same tool, torque, and conductor cross-section for the cir-
cuit breakers, contactors, and overload relays of a single frame size. The
stripping lengths of the conductors are also the same. This is important in
the case of prefabricated wiring.
Screw-type terminals All the devices have screw-type terminals, either a terminal with a top
washer or a box terminal, depending on the frame size.
Devices with frame sizes S00 and S0 have terminals with captive screws
and terminal washers that enable you to connect 2 conductors, even if they
have different cross-sections.
The box terminals of frame sizes S2 to S3 can also take 2 conductors with
different cross-sections.
Connection tools Use the following tools to make the connection:
• Frame sizes S00 to S2: Screws are available for rated currents of up to
50 A for Pozidriv2 screwdrivers.
• Frame size S3: To obtain the required torques for the frame size for up to
95 A, Allen screws are used.
- Frame size S3: Allen screw SW4
The screwdriver guides around the terminal allow screw driving machines to
be used.
Lugs and connecting
bars
You can remove the box terminals from the devices with a frame size of S3
to connect conductors with lugs or connecting bars. A terminal cover is
available as shock protection and to ensure that you comply with the
required creepage and clearance distances when the box terminals are
removed. You can find a detailed description in the forth section of an indi-
vidual chapter entitled “Accessories”.

1.5.3 Cage Clamp1 terminals
The Cage Clamp terminal system is now available for circuit breakers
(MSPs), contactors, overload relays, and time relays.
Cage-type clamping units, known as Cage Clamp terminals in the case of
SIRIUS products, facilitate quick and maintenance-free wiring.
Design The Cage Clamp terminal consists of two parts:
• A power rail for conducting current
• A spring cage-type clamp for clamping strength
Fig. 1-8: Cage Clamp terminal
Conductors The Cage Clamp terminal on the switching devices clamps all copper wires
(single-core, stranded and finely stranded) from 0.25 mm2 to 2.5 mm2. The
conductors can be clamped directly or with some protection for splicing. To
this end, wire end ferrules or pin-end connectors can be placed on the con-
ductor ends. The best solution is an ultrasonically condensed conductor.

Safety The devices are equipped with a two-wire connection. In other words, there
are two independent connections for each conducting path.
Only one conductor is connected to each clamping unit.
The clamp presses the conductor against the power rail, which is curved at
this point. A highly specific compressive load per area is achieved making it
gas tight.
The clamp presses its flat surface against the conductor, thus avoiding dam-
age to it. The spring force of the clamp is designed so that it automatically
adjusts to the radius of the conductor. This allows any deformation of the
conductor to be dealt with. It is not possible for the clamping unit to loosen
by itself.
This connection is vibration- and shock-proof. These types of stress do not
damage the conductor or cause any loss in contact.
Machines and systems in which this type of stress occurs, such as vibra-
tors, rail vehicles and elevators, are particularly suitable applications for this
connection.
Transfer
accuracy
The contact pressure between the conductor and power rail is optimal,
making this clamp terminal suitable for high-voltage installations and also for
the transfer of voltages and currents in the mV and mA ranges in measuring
technology and electronics.
Tool Screwdrivers for opening the Cage Clamp terminals can be obtained from
the SIEMENS low voltage controls catalog.
Procedure The following table shows you how to use the Cage Clamp
Step Procedure
1Insert the screwdriver into
the rectangular opening
until it stops.
The screwdriver head auto-
matically keeps the clamp
open.
2Insert the conductor into
the oval terminal opening.
3Remove the screwdriver.
The terminal closes, and
the conductor is thus
securely clamped.

Small conductor
cross-section
With conductor cross-sections that are ≤ 1 mm2, you should use an insu-
lating stop to avoid contact between a terminal and the conductor insula-
tion.
The illustration below shows the procedure:

1.6 Communication
Fig. 1-10: Communication
1.6.1 Communication-capable low-voltage switching technology
The communication-capable control components from SIEMENS ensures
the user a continuous Automation solution from network up to the control
panel. The concept is based on using AS-Interface and PROFIBUS-DP, the
two standardized and open networking systems, which can be connected to
by virtually all of the known control system manufacturers.
Actuator-sensor inter-
face (AS-Interface)
AS-Interface is a standardized, non-proprietary networking system
(IEC 62026-2) for simple and usually binary actuators and sensors. It is pos-
sible to connect it to SIMATIC programmable logic controllers via different
master modules. A DP/AS-Interface link also ensures direct integration in a
PROFIBUS-DP system or connection to other field buses via couplers. Up to
248 sensors and 186 actuators can be connected to an AS-Interface network
over a maximum of 300 m. Safety-related signals can now also be net-
worked with AS-Interface, thus dispensing with the wiring of emergency
stop signals that were previously needed.
PROFIBUS PROFIBUS is a standardized, non-proprietary networking system
(IEC 61158) to which most PLCs of leading manufacturers can be con-
nected. Up to 125 nodes can be incorporated in one bus segment. Dis-
tances of up to 9.6 km can be bridged with copper conductors and up to
100 km with fiber-optic conductors.

PROFIBUS-DP PROFIBUS-DP (DP being a German abbreviation for distributed I/O) is used
for switching devices with higher communication requirements (e.g. the
transmission of a large volume of data with extremely fast response times).
It is also used to link individual AS-Interface segments.
PROFIsafe PROFIBUS-DP can also transfer safe signals. The PROFIsafe-Protocol can be
used to communicate safe inputs and outputs with a fail safe controller.
1.6.2 Parameterization of PROFIBUS-DP and bus-capable low-voltage switching devices
Before commissioning, PROFIBUS-DP must be configured, and the indi-
vidual bus nodes must be parameterized. There are user-friendly tools
available to the user for configuration and parameter assignments.
Parameter assignment
tools
• For SIMATIC S7 masters, all the functions are integrated in the STEP 7
programming language.
• For SIMATIC S5 masters and various non-SIEMENS masters, the COM
PROFIBUS parameter assignment software is required.
• Manufacturers of non-SIEMENS masters offer other configuration and
parameter assignment programs.
There are various product specific software packages available that allow
you to easily parameterize and diagnose your low voltage control devices
with a variety of functions.
COM SIMOCODE for the motor protection- and control device
SIMOCODE-DP.
SWITCH ES motor starter for ECOFAST Motor starter and
ET 200S High Feature motor starter.
These Software packages are either completely incorporated in STEP 7,
communicated via PROFIBUS-DP or directly via a serial interface with the
respective field device
Applications The above program packages make it easy to carry out the following for
PROFIBUS-DP and its nodes:
• Configuration
• Parameter assignment
• Documentation
• Commissioning
• Testing
• Diagnostics
For additional information on communication-capable low-voltage switching
devices, as well as system components and accessories, see the following
catalogs:
• Industrial Controls Catalog (PC 6000)
• IK PI "Industrial Communication and Field Devices"
• CA01 "Automation- and Drives technology" (CD-ROM)

1.6.3 Actuator-sensor interface (AS-Interface)
Actuator-sensor interface (AS-Interface) is a modular networking system for
sensors and actuators in the lowest field range.
It makes no difference to the program in the programmable controller
whether parallel wiring with input/output modules or AS-Interface is used.
It is therefore possible for existing systems to change to AS-Interface
because you can continue to use the same programs. The entire system can
be operated without additional software. It is not necessary to be familiar
with the internal workings of AS-Interface.
Replacement for the
cable harness
Process signals that occur locally are normally transferred to the open loop
control using extensive parallel wiring and input/output modules. This
means that each sensor or actuator in the field is connected to the input/
output modules with its own cable. AS-Interface makes it possible to
replace this cable harness with a simple two-wire cable for all sensors and/
or actuators.
Data and power on a
two-wire cable
The master communicates with the nodes via the AS-Interface cable. As
well as data, this cable also transfers the supply voltage for node operation
and node inputs, i.e. sensors. The voltage is supplied to the AS-Interface
cable from a special AS-Interface power supply unit with a data link.
Setting up different
structures
The AS-Interface cable is installed in the same way as for an electrical instal-
lation. A new node can be inserted at any point. This makes it possible to
set up network structures (e.g. tree, star or line structures). No shielding or
terminating resistors are required. The wiring can be adapted individually to
the system or machine.
Maximum System
configuration
Detailed configuration and installation guidelines can be found in the instal-
lation guideline "Installation of the AS-Interface networking system" (on
mounting the AS-Interface networking system).
Up to 62 nodes can be connected to the AS-Interface cable. A node is, for
example, an AS-Interface module (digital or analog) or a BERO (proximity
switch) with an integrated AS-Interface chip. A maximum of 4 binary sen-
sors and/or 4 actuators can be connected to an AS-Interface module.
This produces a maximum configuration of 248 inputs and 186 outputs
(62 nodes x 4 inputs and 3 outputs).
Degree of protection AS-Interface is a networking system for direct use on the machine. The
AS-Interface compact module has an IP67 degree of protection. They can be
used without an enclosure.
There are also AS-Interface modules with IP20 protection for use in enclo-
sures or distribution panels.
System overview
SIRIUS System Manual
A5E40534713002A/RS-AA/001 1-25
Installation system All compact modules are placed on a mounting plate. The mounting plate
takes the AS-Interface cable and keeps it in place. Polarity reversal is
virtually impossible due to the profile of the cable. The compact modules
are simply hooked on at the top of the mounting plate and secured with just
one screw. When you secure the modules, contact is made with the AS-
Interface cable. You do not have to strip or screw on the cable.
Coding prevents errors All the modules are mechanically and electrically coded.
The coding system prevents errors occurring in the event of replacement. At
replacement, only one module of the same type can ever be mounted. This
stops digital or analog modules (or even inputs or outputs) getting mixed up.
Addressing To participate in data transfer with the master, each node must be assigned
an address before commissioning of the AS-Interface network. Addressing
devices are available for this.
Addressing an installed
module
There is an additional feature which makes new SIEMENS modules even
more user-friendly: the addressing socket.
Using this socket you can address a module after it has been installed. It is
not necessary to unscrew the module. Installation can be carried out in the
system by personnel who are not familiar with the AS-Interface. The com-
missioning engineer can address the modules easily when they are already
installed. For the first time, this type of addressing is also possible with IP67
protection.
Diagnostics at a glance The new generation of AS-Interface modules (compact modules, analog
modules, and SlimLine modules) has the new display system developed by
SIEMENS.
The status of a module is displayed by two LEDs lighting up continuously or
flashing.
This simple diagnostic feature directly on the module makes it possible for
the user to find the error quickly and efficiently. This in turn reduces down-
times.
Certificates of the
AS-Interface
association
All SIEMENS AS-Interface products are tested in accordance with the rele-
vant testing regulations in an accredited test laboratory and certified by the
AS-Interface association.

Digital compact
modules with IP67
protection
AS-Interface modules in the compact range are characterized by optimized
operating features and improved user-friendliness.
This can reduce mounting and commissioning times for AS-Interface by up
to 40 %. Additional LEDs provide information on the most important operat-
ing modes of the module, resulting in a considerable increase in system
availability.
The modules of the compact range consist of two components:
Mounting plate and compact module
The mounting plate mechanically fixes the AS-Interface profile cables, takes
the compact module, and serves as a template with drill holes.
The compact module contains the electronic components for communica-
tion and the M12 standard connections for inputs/outputs. Up to four sen-
sors and four actuators can be easily and reliably connected to the compact
module using the M12 standard connection.
The mounting plate and compact module are connected to each other by
means of a single screw. Contact is established with the AS-Interface cable
by means of the proven insulation displacement method.
AS-Interface modules in the compact range with an M12 connection can
have a protective conductor (PE) connected to them.
Using an addressing socket integrated in the compact module, you can also
allocate addresses when the module is in place.
Analog compact
modules with IP67
protection
The design of the analog modules has been adapted for the compact
modules. The analog input and output modules each have two channels. You
can connect measuring sensors and analog actuators using standard M12
connectors. The following groups of analog modules exist:
• Input module for two current sensors
• Input module for two voltage sensors
• Input module for two thermal resistors
• Output module for two current actuators
• Output module for two voltage actuators
All the measured values – except for the thermal resistance value of Pt 100
(not linear) – are available in linear form. In other words, the non-linear trans-
mission curve of the thermal resistor sensor is automatically linearized in
the analog module, and measured values can be processed directly in the
programmable controller.
The input and output channels are isolated. Two-wire and four-wire sensors
can be connected. Differential inputs produce considerable suppression of
common-mode interference. The integrating sigma-delta converter ensures
high measurement accuracy.

Safety first –
emergency-Stop via
AS-Interface
AS-Interface is a system that can transmit both standard signals and safety-
related input signals (e.g. Emergency stop) via the same cable.
Only an additional safety monitor and safe modules are required to use
AS-Interface as a safety bus. This enables category 4 in acc. with EN 954-1
to be achieved. A failsafe programmable controller or special master is not
necessary.
The concept and implementation of AS-Interface Safety at Work (AS-Inter-
face SaW) have been tested and certified by TÜV (technical testing associa-
tion).
This means that the system can be converted to the considerably more
flexible AS-Interface network, which is already available, thus eliminating
the need for the complex, separately implemented emergency stop wiring
that has been necessary up to now.
The following components for direct connection to AS-Interface are
available:
• Safety monitors
• Safety modules
• Emergency-Stop devices
• Light curtains
• Laser scanners

A/B-Technique The new AS-Interface-specification allows the doubling of the number of
nodes on the network from 31 to 62. The 31 addresses that are possible in
an AS-Interface network can be subdivided into two separately independent
subaddresses e.g. in 1A and 1B .
If one uses this feature for all 31 slaves, then it is possible to have a maxi-
mum of 62 nodes on one AS-Interface network. The so-called A/B-Slaves
can have a maximum of four inputs and three outputs.
Another function of the new AS-Interface specification V2.1 is the inte-
grated analog value transfer. Integrated means that a special function block
is not required in order to be able to access the analog values. Accessing
data of analog values is therefore just as easy as with digital values. The use
of integrated analog value transfer is possible with analog nodes, that sup-
port Profiles 7.3 and 7.4.

1.6.4 SIRIUS NET Communication-capable motor starter
SIRIUS NET is the name of the family of communication-capable motor
starters from SIEMENS. SIRIUS NET motor starters are available with
AS-Interface and PROFIBUS-interface, in IP20 degree of protection for use
inside the control panel or distribution panel, and in IP65 degree of protec-
tion for use outside the panel and mounted directly on the machine.
SIRIUS NET motor starters consist of completely pre-wired SIRIUS load
feeders/combination starters. This reduces the installation time and wiring
time to a minimum. All of the necessary inputs and outputs are already on
board. Depending on the design there are many Diagnostic functions that
support the user and owner. This reduces downtime and improves effi-
ciency.
3RA5 AS-Interface load
feeder/combination
starter
The preferred use of AS-Interface 3RA5 load feeder/combination starter is in
central control panels (IP65 degree of protection). It’s busbar (Fastbus)
adapter for 40 mm and 60 mm systems allows for quick installation. With
the connection via busbars, a whole range of 3RA5 load feeders/combina-
tion starters can be supplied with power. AS-Interface and auxiliary power
are simply connected by using a plug with insulation piercing connection
technology. The conductor to the motor can be attached without a terminal
strip by using a 5-pole power connector that attaches directly to the starter.
Due to its consistent plug-in technology a 3RA5 load feeder/combination
starter can quickly be changed out. The 3RA5 load feeder/combination start-
ers are available as direct or reversing starters up to 7.5 kW. For larger loads,
devices can be easily assembled by the customer by using standard SIRIUS
and AS-Interface components.

AS-Interface compact
starter
The AS-Interface compact starter is a starter designed to mount directly on
the machine (IP65 degree of protection). The durable plastic housing also
makes it suitable for use in the roughest industrial environment. With only
two screws it can be mounted on to a mounting plate with very little effort
and at the same time it makes contact with the AS-Interface- and auxiliary
power flat cable through the proven AS-Interface penetration technique. The
main power circuit side is quickly connected to the power bus cable and the
motor circuit. Assemblies with a contactor and circuit breaker (MSP) are
available up to 5.5 kW and with electronic contact element and electronic
overload relay are available up to 2.2 kW either as a direct and as reversing
starter. Two inputs on the starter can accept process signals via M12-socket
and route them to the PLC. Starters with brake contacts for an electrically
operated motor brakes are also optional.
ET 200X The ET 200X distributed I/O system with the wide variety of expansion
modules offers the possibility to provide all of the machines functions
directly on the machine - in IP65/IP67 degree of protection. Whether motor
starter, frequency converter, pneumatic or input/output module, whether in
harsh environments, in extreme time critical applications or a large number
of sensors and loads in one place - the modular SIMATIC ET 200X distrib-
uted I/O system offers the corresponding decentralized solution for every
application in the field. ET 200X consistently provides optimal communica-
tion with the high level system via PROFIBUS-DP. A single basic module
allows the addition of up to 6/7 expansion modules. With the AS-Interface-
Master module in the ET 200X, a mixture of networks can be very easily
attained at a reasonable price. The distributed signals in the installation can
also be optimally incorporated with very little set-up effort. With the intelli-
gent basic module for data preprocessing and control, distribution of self-
supporting and time-critical functions can be realized independent from the
higher level PLC. Only the most important control signals and diagnosis data
is then sent over PROFIBUS. This relieves the network as well as the high
level control. The programing and planning of these types of stations is
done with SIMATIC standard tool STEP7.
ET 200X motor starter The ET 200X motor starter is available in the same designs as the AS-Inter-
face compact starter. That means, as an electro-mechanical starter up to
5.5 kW, electronic starter to 2.2 kW. For further details see above. There is a
hand-held controller available that can also be used with both motor starter
families for activation at prestart-up and for service use.
ET 200S The ET 200S distributed I/O system, using PROFIBUS-DP, offers a plurality
of 2- and 4-channel input/output modules, Technology modules, such as
Standard motor starter, High Feature motor starter and safety technology
that can be configured almost any way you want in a fine modular form. The
modules with IP20 degree of protection are used in central control panels as
well as decentralized panels. All of the voltage potential only needs to be
supplied once. Through simple side-by-side mounting of the terminal mod-
ules the auxiliary power as well as the main power voltage are automatically
transferred. The purely passive terminal modules are the basis for the elec-
tronic modules that mount on them. These electronic modules can also be
removed or added while in the system is running. This safeguards the
accessibility of the machines and installation.

A5E40534713002A/RS-AA/001 1-31
ET 200S motor starter The ET 200S motor starters are completely pre-wired SIRIUS load feeders/
combination starters with short-circuit protection and overload protection.
The required inputs and outputs for control and monitoring are already inte-
grated in the motor starter. The correct function of the motor starter is
monitored without any additional programming and will initiate a clear error
signal via PROFIBUS-DP if needed.
ET 200S SIGUARD The motor starters can be expanded for technical safety applications
(EN 954-1) with the SIGUARD power modules. Emergency-stop buttons,
safety limit switches or other floating contacts from safety devices use a
two channel connection. The functions on the sensor side are in accordance
with the standard and are monitored for, among other things, cross-circuit or
short-circuit. The integrated safety relays also check the proper switching of
the motor starters listed below. Additionally ET 200S Standard motor starter
requires a so-called F-Kit - a front mounted auxiliary contact- (return circuit).
The High Feature motor starter comes with these contacts already factory
installed. A special Connection module needs to be installed at the end of a
safety segment with one or more motor starters. For applications that
require category 3 or 4 (EN 954-1) a redundant infeed contactor needs to be
connected to the connection module (control and monitoring). For applica-
tions that require category 2 the return circuit needs to be closed on the
Connection module by using a jumper.
ET 200S Standard
motor starter
ET 200S Standard motor starter consists of a circuit breaker (MSP) and con-
tactor combination from the SIRIUS S00-Frame size. At a maximum rating of
5.5 kW, the motor starter gets power from the terminal module on the self-
establishing power bus (40 A). All that remains per motor starter is simply
adding the three conductors of the motor load and optional neutral/ground
connection. Distribution wiring on pre-stored terminal blocks is no longer
necessary, since the terminal modules already provide this function.
ET 200S High Feature
motor starter
The ET 200S High Feature motor starter is a new class of load feeder/combi-
nation starter up to 7.5 kW. Motor circuit breaker (MSP) for short-circuit pro-
tection, electronic overload relay for the overload protection, and contactor
or soft start for switching the circuit offer a range of new features:
• The devices in frame size S0 have achieved Type 2 coordination for the
current ratings up to 16 Amps (7.5 kW). That means, that even after a
short circuit in the range of 50 kA the motor starter will not be destroyed
and can still be used. Only light welding of the contacts, without any
deformity worth mentioning and which can be separated by the user, is
permitted.
• The current monitoring in all three phases serves as both the overload
evaluation and as the processing in the high level control. As an alterna-
tive to cyclic current value transmission it is also possible to set of an
upper and a lower limit value for each. These can be used, for example,
for the load dependent, autonomous shutting off of the starter.
• All of the settings, as well as the rated motor current are automatically
transferred to the new starter by the high level controller in the event a
starter needs to be exchanged.
System overview
SIRIUS System Manual
1-32 A5E40534713002A/RS-AA/001
• In the case of an exchange you only need to choose between two starter
types. The electronic overload relay offers an extraordinary adjustment
range (0.3 to 3.0 A and 2.4 to 16 A).
• In some critical applications the process can be more important than the
protection of the motor. That is why under the estimation and supervision
of the user there is the possibility with the High Feature motor starter to
suppress the overload tripping function and continue operation of the
motor starter with the emergency start function.
The quickest assembly through completely pre-wired and simple plug-in
technology were added so that a range of functions could lead to increased
system availability. This makes the starter especially suitable for applications
that contain both time-critical and valuable processes.
ET 200S Failsafe motor
starter
The ET 200S Failsafe motor starter takes the advantages of the High
Feature motor starter and supplements them with the requirements from
the Safety technology. An integrated monitoring function checks whether or
not the contactor opens properly when the motor starter is turned off. For
example, should the contactor be welded and therefore can’t open, the cir-
cuit will be automatically opened by the motor circuit breaker (MSP). It
therefore meets the required redundancy of EN 954-1 for category 4 with-
out any additional mounting or wiring time. You can assign up to 6 separate
safety circuits of different motor starters inside of a single station to each
upstream power module. The control takes place either over a Safety
related control system, for example SIMATIC S7-300F and PROFIBUS-DP
(PROFIsafe) or over a separate safety switching device, for example the
safety monitor from AS-Interface Safety at Work.
The advantage in using the Failsafe motor starter solution lies in the flexible
order of various safety circuits and the integrated switching redundancy in
every starter. The cost to achieve this type of installation with conventional
technology would be much higher. However, if a larger group of motor
starters in one safety segment is needed, then a solution with ET 200S
SIGUARD could be the more favorable one.
For its safety function, the Failsafe motor starter requires that the contactor
contacts are electrically isolated from each other. Therefore, a design with a
softstarter function is not available.
Switch ES motor
starter
The Switch ES motor starter, the easy to use configuration and diagnoses
tool, not only lets you comfortably configure and diagnose the High Feature
motor starter while in operation with an on the spot point-to-point connec-
tion, but also supplies a range of additional information, such as statistics
data. That way the operating hours or the motor current during the last over-
load trip can be called up. Important information on the condition of the
installation can then be derived. The control function also comfortably lets
you test the motor starter without high level control, such as at prestart-up.

2.2 Device description
3RV1 circuit breaker/MSPs are used to switch and protect three-phase
induction motors of up to 45 kW at 400 V AC (100 HP at 600 V AC) and for
loads with rated currents of up to 100 A.
The 3RV1 circuit breaker/MSPs have 3 poles. To achieve the highest degree
of flexibility, auxiliary switches, alarm switches, auxiliary releases, and other
accessories can be easily attached to the circuit breaker/MSPs without
tools.
3RV1 circuit breaker/MSPs and 3RT1 contactors work together both electri-
cally and mechanically. This enables them to be easily and quickly put
together to make load feeders.
Frame sizes 3RV1 circuit breaker/MSPs are available in 4 frame sizes (S00 to S3).
Fig. 2-1: 3RV1 circuit breaker/MSPs (frame sizes S00 to S3)
The following table shows you the frame sizes and the corresponding maxi-

2.2.1 General description
Fields of application The 3RV1 circuit breaker/MSPs are suitable for:
• Motor and plant protection
• Starter protection (short-circuit protection)
• Transformer protection
The 3RV16 11-0BD10 circuit breaker/MSP, frame size S00, is used for fuse
monitoring.
Releases 3RV1 circuit breaker/MSPs have:
• Inverse-time delay, thermal overload releases
• Instantaneous short-circuit releases
The overload releases can be set to the load current.
The short-circuit releases are set permanently to 13 times the rated current,
which allows motors to start up without problems. Circuit breaker/MSPs
used for transformer protection are set to 19 times the rated current to
avoid being tripped by the high inrush current.
When the circuit breaker/MSPs are tripped, in the case of frame size S00
the toggle switch goes into the tripped position, and in the case of frame
sizes S0 to S3 the rotary switch switches to the tripped position. Before it is
switched on again, the rotary switch must be put in the 0 position manually
(reset) to avoid switching to the fault inadvertently.
In the case of circuit breaker/MSPs with a rotary switch, the tripping opera-
tion can also be reported electrically by means of an alarm switch.
Tripping classes In acc. with IEC 947-4-1:
• Frame sizes S00 to S3: class 10
• Frame sizes S2/S3: class 20
Auxiliary release The circuit breaker/MSPs can also be equipped with one of the following
auxiliary releases:
• Shunt release
• Undervoltage release
• Undervoltage release with leading auxiliary contacts
Auxiliary contacts The 3RV1 can use a transverse auxiliary contacts and/or a side mounted
auxiliary contacts (Section 2.4 Accessories).
Shock protection All frame sizes S00 to S3 are touch safe according to DIN VDE 0106
part 100. Additional protection covers are offered for frame sizes S2 and S3.
• Frame size S2, S3: terminal covers for box terminals
• Frame size S3: terminal covers for lug and bar connection

2.2.2 Operation
Current setting Using a screwdriver, set the load rated current (current setting) Ie on the
scale of the 3RV1.
The proper dial setting will depend how the 3RV1 will be installed. There are
two determining factors:
1. Stand-alone installation: without a directly mounted contactor and clear-
ance left and right of a minimum 10 mm.
2. Side-by-side installation: with a directly mounted contactor and clear-
ance left and right of less than 10 mm. This is the typical installation
method.
Note the two possible dial markings on the dial:
• Dash mark: Is the dial marking used when the 3RV1 is being applied in
stand-alone installation
• Triangle mark: Is the dial marking used when the 3RV1 is being applied in
side-by-side installation
In both cases the ambient temperature may be +60 °C and the complete
current range can be used up to the highest setting. The relevant dial mark-
ing (Dash or Triangle) should be set according to the required current set-
ting. At temperatures over +60 °C current derating is necessary. The maxi-
mum allowable current setting for an ambient temperature of +70 °C can be
determined by a slightly longer setting line on the current scale.

Locking the circuit
breaker/MSPs
You can prevent the circuit breaker/MSP from being switched on by unau-
thorized persons by securing the switching mechanism (toggle switch or
rotary switch) with a padlock (shackle diameter 3.5 to 4.5 mm)
The device can only be locked in the Off position.
Fig. 2-5: Locking the toggle and rotary switch (example: frame size S00 and S0)
Resetting after a tripping operation
When the circuit breaker/MSP trips, the switch goes into the tripped position.
You use the switch to close the circuit again.
In the case of frame sizes S0 to S3, the rotary switch must be manually
turned to the OFF position after the device trips. Then the circuit breaker/
MSP can be turned on again.
In the case of frame sizes S2 and S3, it is possible to switch on and off using
a motorized remote-control mechanism (see Section 2.4, Accessories).

Short-circuit protection The short-circuit releases of the 3RV1 circuit breaker/MSPs execute a three-
phase isolation of the faulty branch circuit from the network and prevent any
further damage.
With a short-circuit breaking capacity of 50 kA or 100 kA a voltage of
400 V AC, the switches are considered to be short circuit-proof, since
higher short-circuit currents are not to be expected where the switches are
installed.
Backup fuses are only required if the short-circuit current at the point of
installation exceeds the rated short-circuit breaking capacity of the circuit
breaker/MSPs.
You will find the short-circuit breaking capacity for other voltages and the
sizing of any required fuse listed in Section 2.7, Technical specifications.
Conditions of
application
3RV1 circuit breaker/MSPs are climate-proof. They are intended for use in
closed areas where there are no hazardous operating conditions such as
dust, corrosive fumes or destructive gases.
Appropriate housings are available as an accessory for use in dusty and
damp areas (see Section 2.4).
Selection Operational currents and starting currents can vary even in motors of the
same power. The motor powers listed in the tables are to serve only as
guide values. Most important when selecting the correct circuit breaker/
MSPs are the specific starting data and rating of the motor to be protected.
This also applies to circuit breaker/MSPs used for transformer protection.
Phase loss
sensitivity
The phase loss sensitivity of the circuit breaker/MSP ensures that it trips in
the event of the loss of a phase and the resulting overcurrents in the other
phases.
During normal operation, the device should have a three-pole load. To pro-
tect single-phase loads or direct current loads, all 3 main conducting paths
should be switched in series
Explosion protection Note
In the case of a three-pole load, at 3 to 8 times the set current, the release
time deviates by a maximum of ± 20 % and therefore complies with the
requirement of DIN VDE 0165 and EN 50019.
The 3RV10 circuit breakers (MSP) for motor protection, CLASS 10, and the
3RV11 circuit breakers for motor protection with overload relay function,
CLASS 10, have ATEX-Approval according to EU-requirement 94/9/EG
(DMT-Certificate).

Characteristics The tripping characteristic of the inverse-time delayed overload release
(thermal overload release, a-release) is valid for direct current and
alternating current with frequencies of 0 to 400 Hz.
The characteristics are valid for tripping operations from a cold state. From a
warm state, the release times can be reduced up to 75 % depending on the
motor current and the ambient temperature.
The tripping characteristics of the instantaneous electromagnetic overcur-
rent releases (short-circuit release, n-release) is based on the rated current
In, which in the circuit breaker/MSPs with adjustable overload releases is
also the upper value of the adjustment range.
The following is a chart of the time-current characteristic:

teristics can be requested directly from your sales representative, if neces-

Frequency sensitivity of
the short-circuit
releases
The characteristics of the short-circuit releases apply to frequencies of
50/60 Hz. For lower frequencies, such as 16 2/3Hz, for higher frequencies
up to 400 Hz, and for direct current, appropriate correction factors have to
be taken into account.
The following characteristic curve illustrates the frequency sensitivity of the
short-circuit releases:

2.3 Application and areas of use
The tripping characteristics of the 3RV1 circuit breaker/MSPs are designed
primarily to protect three-phase induction motors. The circuit breaker/MSPs
are therefore also referred to as motor protecting switches. In Europe, the
3RV10 circuit breaker/MSPs for motor protection can also be used in the
protection of systems.
2.3.1 Motor protection
Current setting The current of the motor that is to be protected is set on the adjustment
scale. This sets the integrated overload protection of the motor current. The
short-circuit release is set at the factory to 13 times the value of the rated
current (the highest value on the current scale) of the circuit breaker/MSP.
This ensures problem-free startup and reliable protection of the motor.
Phase loss
sensitivity
The phase loss sensitivity of the circuit breaker/MSP ensures that it trips in
the event of the loss of a phase and the resulting overcurrents in the other
phases.
CLASS10/CLASS20 Circuit breaker/MSPs of frame sizes S00 to S3 (0-100 A) with thermal over-
load releases comply with tripping class 10 (CLASS 10). Circuit breaker/
MSPs with the CLASS 20 tripping characteristic are also available for frame
sizes S2 and S3 (11-100 A) for longer startup conditions.
2.3.2 Transformer protection
Inrush current In the case of primary protection of control transformers, the high inrush
currents that occur when the transformers are switched on often result in
the unwanted tripping of the protective devices.
Therefore, the 3RV14 circuit breaker/MSPs have overcurrent releases for the
protection of transformers that are set at the factory to approximately 19
times the rated current. This makes it possible to protect transformers in
which the inrush currents reach peak values of up to 30 times the rated cur-
rent with circuit breaker/MSPs in the primary circuit. The 3RV14 for trans-
former protection come in frame sizes S0 and S2 (0 to 40 A).
In the case of control transformers with low inrush current (SIEMENS 4AM
control transformers, for example), this is not required. 3RV10 circuit
breaker/MSPs can be used. In these lower inrush applications the 3RV14
devices are not UL listed for the protection of transformers.
2.3.3 Starter protection The 3RV13 starter protection switches are circuit breakers without overload
releases. They are used together with a contactor and overload relay if the
circuit breaker/MSP is not to be triggered in the case of overload tripping.
Like the 3RV10 the short-circuit release is set at 13 times the rated current.
The 3RV13 are available in frame sizes S0 to S3 (0 to 100 A).

SIRIUS System Manual
2-14 A5E40534713002A/RS-AA/001
2.3.4 Motor protection with overload relay function
3RV11 circuit breakers/MSPs with the overload relay function are available
for frame sizes S0, S2, and S3.
Description The 3RV11 devices have the same overload and short-circuit trip characteris-
tics as the 3RV10. However the overload release doesn’t effect the switch-
ing mechanism of the circuit breaker/MSP. In the event of an overload, the
circuit breaker/MSP remains switched on.
The overload release uses two side mounted auxiliary contacts
(1NO + 1NC), that switch in the event of an overload. The auxiliary contacts
can be used for signalling or can be used to disconnect a downstream con-
tactor. After the circuit breaker/MSP has cooled down, the auxiliary contacts
are reset automatically.
Caution
In the overload range, the circuit breaker/MSP does not protect itself with
the overload relay function. You must therefore ensure that the power is
safely disconnected by means of a downstream switching device (e.g. a
contactor).
Fixed link: auxiliary
contacts with circuit

Note
The auxiliary contacts are factory mounted to the 3RV11 circuit breaker/MSP
on the right side and cannot be removed.

2.3.5 Switching direct current
The 3RV1 circuit breaker/MSPs for alternating current are suitable for
switching direct current. However, you must note the maximum permissible
DC voltage per conducting path. In the case of higher voltages, series con-
nection of 2 or 3 conducting paths is required.
Response thresholds The response thresholds of the overload releases remain unchanged. The
response thresholds of the short-circuit releases are increased with direct
current by approximately 40 %.
The following table lists suggestions for switching direct current:
Double ground fault Note
In the case of the circuit with 2-pole switching and an ungrounded system, it
is assumed that even in the event of a double ground fault that bridges two
contacts, safe disconnection still occurs.
2.3.6 Main and emergency stop switches
Since the circuit breaker/MSPs meet the requirements for disconnectors in
acc. with IEC 60947-3 and the additional test requirements for circuit
breaker/MSPs with disconnector features in acc. with IEC 60947-2, they can
be used with the appropriate accessories as main and emergency stop
switches. They must also comply with DIN VDE 0113.

tripping operation, irrespective of whether it was caused by a short cir-
cuit, overload or auxiliary release.
• The other contact system (1 NO + 1 NC) only switches in the event of a
short circuit tripping operation.
To reset the circuit breaker/MSP after a short circuit, the alarm switch must be
reset manually after the cause of the error has been eliminated.

Function and use, see undervoltage release.
Additional function:
The auxiliary contacts isolate the undervoltage release from the power
system on both sides in the event of breaking or a tripping operation and
thus prevent voltage distortion to the control circuit when the switch is in
the off position.
It is possible to reset the circuit breaker/MSP because the contacts reset.

2.4.2 Auxiliary contacts 3RV19 01-.., alarm switch 3RV19 21-111 and auxiliary release 3RV19 .2-....
The maximum configuration for each 3RV1 circuit breaker/MSP is one trans-
verse auxiliary contact, one side mounted auxiliary contact with 2 contacts,
one alarm switch, and one auxiliary release. An alternative to the transverse
auxiliary contacts and one side mounted auxiliary contact with 2 contacts
would be to use a side mounted auxiliary contact with 2 NO + 2 NC. So
with any one circuit breaker/MSP a maximum of 4 auxiliary contacts with
auxiliary release can be used.
Possible combinations The following combinations of auxiliary switches and alarm switches or of
auxiliary switches are possible:
• Auxiliary contacts with 2 contacts and alarm switches can be installed
individually or together. The side-mounted auxiliary contact is installed on
the left of the alarm switch.
• Transverse and lateral auxiliary switches can be combined. Maximum of
4 auxiliary contacts is possible.
• One auxiliary release can be attached on the right for each circuit breaker/

the thru-the-door rotary operator:
Opening the door with
great force
Note
If the circuit breaker/MSP is in the ON position and the door is opened with
a force >150 N to 200 N, the cap of the extension shaft is separated from
the rotary switch of the circuit breaker/MSP to prevent the circuit breaker/
MSP being destroyed.
The circuit breaker/MSP remains in the ON position.

2.4.6 Terminals for "Combination Motor Controller Type E" in acc. with UL 508
Since July 16, 2001, 1 inch air clearance and 2 inch creepage distance is
required for "Combination Motor Controller Type E" on the input side in acc.
with UL 508. For the 3RV10 circuit breakers/MSPs frame size S0 use termi-
nal block 3RV1928-1H and for frame sizes S3 use terminal block
3RT1946-4GA07. The 3RV10 in frame size S2 complies with the required air
clearance and creepage distance without a terminal block.
These terminal blocks cannot be used in the S0 frame size at the same time

2.4.8 Busbar adapter 8US1 (Fastbus system)
To enable the circuit breakers/MSPs to be mounted without using up too
much space, and to ensure that the infeed is economical in terms of both
time and money, the switches can be mounted directly onto busbar systems
using busbar adapters.
The circuit breakers/MSPs are snapped onto the adapter and connected at
the input side. This prepared unit is mounted directly onto the busbar sys-
tems, thus both attaching it mechanically and establishing electrical contact.
Busbar systems The adapters are suitable for the following systems:
Accessories The following accessories are available for busbar adapters:
• Modules that can be mounted on either side to widen the adapters
• Busbar holder for 3 rails
• Molded-plastic covers for 3 terminals (40 mm system)
• Molded-plastic cover profiles for shock protection

2.4.9 Isolated 3-phase busbar system
For 3RV1 frame sizes S00, S0, and S2, 3-phase busbars can be used to
quickly and easily provide line side feeding when mounting circuit breakers/
MSPs on to DIN rail. There is only one power supply, via a feed-in terminal.
The 3-phase busbar systems are safe from fingers and are shock protected
DIN VDE 0106 Part 100. They are rated for the short-circuit stress that can
occur on the output side of the connected circuit breakers/MSPs.
Fig. 2-30: 3-phase busbar system (example: frame size S00)

Combination of
frame sizes S00
and S0
Circuit breakers/MSPs in frame sizes S00 and S0 vary in height and depth.
They therefore cannot be combined on one busbar. You can combine two
busbars for circuit breakers/MSPs in frame sizes S0 and S00 using an exten-
sion piece.
Extending the bus It is possible to extend the busbars by clamping the connecting lugs of a
another bus (turned 180°) under the terminals of the last circuit breaker/MSP
(see the section on mounting).
Attention
Note the current-carrying capacity of the busbars when you extend them.
Accessories The following accessories are available for the isolated 3-phase busbar sys-
tem:
• Feeder lugs from above (3RV1915-5A for S00, 3RV1925-5AB for S0,
3RV1935-5A for S2)
• Feeder lugs from below (3RV1915-5B for S00, S0)
• Connector
A connector links two 3-phase busbars over a space of 45 mm for circuit
breakers/MSPs in frame size S0 (left) and frame size S00 (right).
• Protective cap for connecting lugs (3RV19 15-6AB)
Protective caps provide shock protection for spare slots. To extend the
bus, remove the protective caps.
Feeder lugs 3-phase feeder lugs make it possible to have greater conductor cross-sec-
tions than on the circuit breaker/MSP itself.
Tightening torque: 2 to 4 Nm (17.6 to 35.2 lb·in).
Feeder lugs – connec-
tion from below
Attention
The feeder lugs with connection from below is clamped on instead of a cir-
cuit breaker/MSP. Make sure you check how much space you require when
planning the 3-phase busbars.

• Frame size S3: Allen key (4 mm)
Conductor
cross-sections
The typical SIRIUS conductor cross-sections apply (see Section 1.5.4
"Conductor cross-sections").
Screw-type terminals 3RV1 circuit breakers/MSPs with frame sizes S00 and S0 have terminals
with captive screws and terminal washers that enable you to connect
2 conductors, even if they have different cross-sections.
The box terminals of the circuit breakers/MSPs of frame sizes S2 and S3 can
also take 2 conductors with different cross-sections. With the exception of
circuit breakers/MSPs of frame size S3, which have terminal screws with a
4 mm Allen screw, all the terminal screws can be tightened using a standard
screwdriver or a Pozidriv screwdriver (size 2).
You can remove the box terminals from circuit breakers/MSPs with a frame
size of S3 to connect conductors with ring-tongue or connecting bars.
A terminal cover 3RT19 46-4EA1 is available as shock protection and to
ensure that you comply with the required creepages and clearances when
the box terminals are removed.
Soldering pin

2.7.2 Permissible rating of approved devices for North America, u s
In North America the 3RV1 is not approved as a “circuit breaker” and is commonly known as a Motor Starter Protector (MSP). The
SIRIUS 3RV1 series are approved for u/s and can also be used in acc. with UL 508 and C22.2 No.14 with a contactor as a Type F combi-
nation starter. You can use these MSPs as a "Manual Motor Starter" for "Group Fusing" or for "Group Installation" or as a "Combination Motor
Controller Ty p e E ".
3RV1 as a "Manual Motor Starter"
When the 3RV1 is used as a "Manual Motor Starter", it is always with a device for short-circuit protection (upstream short-circuit pro-
tection device). Any fusible link (“group fusing”) or UL 489 listed circuit breaker (“group installation”) can be used as a device for short-
circuit protection. The type and size are selected in acc. with the American NFPA 70 standard, Article 430-53 (c) for adequate protec-
tion of supply wiring.

Since July 16th 2001, 1 inch air clearance and 2 inch creepage distance is required for a "Combination Motor Controller Type E" on the
input side with UL 508 The 3RV10 in frame sizes S0 and S3 are therefore approved with the terminal blocks listed below in acc. with
UL 508.
The 3RV10 in frame size S2 already complies with the required air clearance and creepage distance as a basic unit. These extended air
clearances and creepage distances are not required for CSA. The terminal blocks are therefore not required for use as a "Combination
Motor Controller Type E" in acc. with CSA. 3RV10’s are certified as "Combination Motor Controller Ty p e E " under the following file num-

2.7.3 Short-circuit breaking capacity Icn in acc. with IEC 60 947-2
The table lists the rated limit short-circuit breaking capacity Icu and the rated service short-circuit breaking capacity Ics of 3RV1 circuit
breakers with different inception voltages and related to the rated current In of the circuit breakers.
The incoming supply of the circuit breakers is permissible at the upper or lower terminals irrespective of the rating.
If the short-circuit current at the installation location exceeds the rated short-circuit breaking capacity of the circuit breaker specified in
the table, a backup fuse is required. You can also use an upstream circuit breaker with a limiter function.
The maximum rated current of this backup fuse is specified in the tables. The rated short-circuit breaking capacity specified for the
fuse then applies.
Circuit breaker/contactor combinations for short-circuit currents of up to 50 kA can be used as fuseless load feeders in acc. with Part 5.

2.8 Application notes for the use of 3RV1 downstream from frequency
converters/inverter with pulsing voltage
The use of thermal motor protection devices downstream from frequency
converters/inverters with pulsing voltage results in influences on the switch-
ing devices that could lead to the nuisance tripping of those devices. In the
following examples, practical guidelines are provided for such applications.
2.8.1 Influences of high frequency currents upon the thermal overload release
The thermal overload release on the circuit breakers/MSPs and overload
relays generally consists of a bimetal strip and a heating winding, that heat
up when motor current runs through them. The excessive bending of the
bimetal strip (such as with high motor current) results in the breaking of the
motor circuit.
This style of thermal overload release is set for 50 Hz AC current. So that the
trip point is also only for currents which have the same thermal effect (r.m.s.
value) or are similar to the set current in the required range of the standard.
This would be the case for AC current from 0 to 400 Hz and for DC current.
With high frequency currents, as occurs downstream of converters, the
bimetal strip becomes increasingly hot. This can be attributed to eddy
current loses induced by harmonics and to the Skin effect in the heater
windings. Both lead to the tripping of the overload release even with lower
currents (nuisance tripping!).
The influences are dependent on the frequency of the current. The higher
the frequency of the converter and the lower the adjustable range/rated
current, the higher the reduction of the trip current.
In order for the trip limits to once again fall into the standard range, the over-
load release setting needs to be corrected. The following table shows the
correction factors for the various setting ranges depending on the pulse
frequency of the converters.

Table 2-20: Correction factors for the various setting ranges
Circuit breaker/MSP 3RV1
SIRIUS System Manual
A5E40534713002A/RS-AA/001 2-73
Example Circuit breaker/MSP with the setting range of 1.1 - 1.6 A behind a frequency
converter with a pulse frequency of 8 kHz and a r.m.s. value of the motor
current at rated load: 1.2 A.
Set to: 1.2 A x 1.21 = 1.45 A
This compensates for the influences of the high frequency current. The trip
current lays within the standard range.
Attention
Harmonics can cause the r.m.s. value of the motor current to be higher than
the rated motor current. In this case nuisance tripping can still occur despite
the use of the correction factors.
In order to remedy this, the r.m.s. value of the motor current at rated load
needs to be ascertained and used as the basis current for the above
described correction procedure. Only measuring instruments suitable to
ascertain the values are those that can measure the true r.m.s. value up to
the frequencies that appear and can also reproduce them. Devices well suit-
able for this would be hot-wire instruments for example. Moving-iron mea-
suring elements are in fact r.m.s. measuring instruments, but can only be
used for frequencies up to 1 kHz and therefore can’t be used in most of the
above described cases. Common instruments such as a multimeter or a clip-
on ammeter are not suitable for measuring in the above described cases.
2.8.2 Other possible influences
a) Capacitive leakage currents
Despite adjusting the setting, nuisance tripping can still occur in individual
installations. Extensive investigations have shown that installations with
pulsing voltage can also lead to other effects that lower the trip current of
the overload release, such as an increase of current flowing through the trip
element.
A practical example:
Consider an installation that is fed from an inverter with 3 kHz pulse fre-
quency and has motors connected with a 80 m long cable. An analysis of the
actual flowing current shows a ripple amplitude of the motor current with
very high frequency currents (up to 150 kHz) and a peak value of 1.5 A. The
influence on the thermal overload release is still significantly higher than
described in example 1 at these frequencies. Moreover, capacitive leakage
currents appear in this installation due to the length of the cable and the
high frequency. These increase the current that flows through the trip ele-
ment and can lead to nuisance tripping.
In cases where high frequency currents of well over 16 kHz appear and the
procedure described in example 1 no longer leads to success, then you can
proceed as follows. In an overload free operation of the motor the overload
release needs to be set so high that the unit will not trip. After that the
motor needs to run for about 1.5 h at full load. Then the overload release
needs to be reduced to the trip limit and then set about 10 % higher than
Circuit breaker/MSP 3RV1
SIRIUS System Manual
2-74 A5E40534713002A/RS-AA/001
the trip limit. That will compensate for the influences of the installation. You
can then can use the achieved value as a correction factor for similar installa-
tions.
b) Rotational speed control of motors with a response characteristic
controlled Frequency converter
With the adjustment of the linear voltage-frequency-characteristic and a con-
tinual increase in current (see for example operating instructions Micromas-
ter parameter P077 and P078), decreased rotational speed (< 50 Hz) and
constant load torque can lead to the increase of the motor current. With this
adjustment the frequency converters output voltage is not reduced to the
same scale as the output frequency. If this results in nuisance tripping and
can’t be compensated for by a higher setting of the trip release (watch for
motor overload), then minimizing of the current increase or a readjustment
to a quadratic voltage-frequency-characteristic could provide a remedy.

Utilization category
for AC voltages
Definition of AC-1 to
AC-6b
The definitions of the utilization categories AC-1 to AC-6b for main circuits
can be found in the relevant regulations.
The main areas of application for contactors are:
• AC-3 operation: switching of squirrel-cage motors
• AC-1 operation: switching of resistive loads
• AC-4 operation: plugging, reversing, inching
• AC-6b operation: switching of capacitor banks
Test conditions Test conditions for the various utilization categories:
• In AC-1 operation, the contactor must be able to switch 1.5 times the
rated operational current on and off.
• In AC-3 operation, the starting currents of the motors must be controlled.
In other words, the contactor must be able to switch on 10 times the
rated operational current (Ie), and switch off 8 times the Ie.
• In AC-4 operation, the contactor must be able to switch off or on 12 times
the rated operational current (Ie) and 10 times the Ie. This represents
extremely high stress for contactors because the high starting currents of
the motors have to be switched off.
• In AC-6b operation, the rated values of capacitor loads may be derived
from capacitor switching tests or on the basis of existing experience and
research.
The breaking current is decisive in calculating the electrical service life:
• In AC-1 and AC-3 operation, 1 x Ie must be assumed.
• In AC-4 operation, 6 x Ie must be assumed because the contactor also has
to switch off the motor during startup.

Rated operational
currents
The rated operational currents for the various utilization categories are listed
in the low-voltage switching devices catalog. The test specifications given in
the table for each utilization category represent the scale for the making and
breaking capacity of the auxiliary contacts.
Example 3RT1016 contactor:
Ie/AC-15 of the auxiliary contact: 6 A/230 V
Making capacity: 10 x Ie/AC-15 = 60 A
• This enables the contactor coil with the current consumption of 60 A to
be switched on.
• Only the holding current is decisive for switching off the contactor coil.
According to regulations, the auxiliary contact must normally be able to
switch off the rated operational current.
Utilization category for
DC voltage (auxiliary
contact elements)
Definition of
DC-12 and DC-13
The DC voltage switching capacity of auxiliary contacts is defined in utiliza-
tion categories DC-12 and DC-13.
The main areas of application for contactors are:
• DC-12: switching of resistive loads (typical application)
• DC-13: switching of inductive loads, such as contactor coils and solenoid
valves
In DC operation, the difference in stress is also determined by the L/R time
constant. This must be specified by the user.

3.1.2 Positively driven operation
Regulations The regulations for positively driven operation are:
SIRIUS contactors comply with these regulations.
Definition: positively
driven contacts
Positively driven contacts are contacts that are mechanically connected with
one another in such a way that the NC contacts and NO contacts can never
be closed at the same time. This means ensuring that there is a distance
between the contacts of at least 0.5 mm throughout the entire service life
of the contactor, even when there is a defect, such as when the contact has
been wrongly welded (ZH 1/457).
Positively driven
operation in the case
of 3RT1/3RH11
Positively driven operation occurs in:
• 3RT101. contactors and 3 RH11 auxiliary contactors in frame size S00 in
both the basic unit and in the auxiliary switch block and also between the
basic unit and the built-on auxiliary switch block
• 3RT1 contactors in frame sizes S0 to S3 between the main contacts and
the normally closed auxiliary contacts. In other words, if the main contact
is welded, the normally closed auxiliary contact will not close.
Positively driven operation does not occur in the case of:
• Electronically optimized auxiliary switch blocks in frame size S00
Positively driven operation is not compulsory for normal controllers. It is,
however, imperative for protective circuits.
3.1.3 Safe isolation
The term "safe isolation" occurs in connection with safety/protective extra-
low voltage (SELV/PELV) and functional extra-low voltage (FELV). Safe isola-
tion reliably prevents voltage that is capable of causing electric shock from
transferring to the safely isolated voltage (e.g. to safety extra-low voltage
that is applied to or switched to the same device).
Safe isolation is also becoming increasingly important due to the more wide-
spread use of electronic systems in high-voltage installations.
Definition Circuits are safely isolated when a single fault does not result in a transfer of
voltage from one circuit to another. Faults to be taken into account are, for
example, a bent or loose conductive part, a bent soldering pin, broken wind-
ing wire, a screw that has fallen out, or a broken partition wall in a device.

3-8 A5E40534713002A/RS-AA/001
Regulations IEC 61 140 (replacing VDE 0106 Part 101/IEC 536) lists basic requirements
that can be met using safe isolation between circuits in electrical equip-
ment.
Basic requirements are, for example:
• Double or reinforced insulation
• Protective screening
• Combination of double or reinforced insulation and protective screening
The insulation must be resistant to aging throughout the expected service
life.
Circuits without protective extra-low voltage or functional extra-low voltage
do not require safe isolation.
Safe isolation in the
case of 3RT1 and 3RH1
contactors
If the conducting paths of a contactor are operated with different voltages,
the requirements for safe isolation must be met.
In the case of the 3RT1 and 3RH1 contactors, safe isolation is ensured up to
the following voltage:
• The values for the safe isolation between the main power circuit and the
auxiliary circuit/coil connection are found in the following tables:

Attention
In the table, the voltage that can cause electric shock and that must be
safely isolated is critical. If the voltages 400 V and 24 V are to be safely iso-
lated from one another, contactors with safe isolation up to 400 V must be
used between the two points of connection used.
3.1.4 Explanation of terms
Safety extra-low
voltage
Safety extra-low voltage (SELV) allows circuits with a rated voltage of up to
50 V AC or 120 V DC to be operated ungrounded. The higher voltage is
safely isolated from the SELV circuits.
Safety extra-low voltage helps protect people.
Functional extra-low
voltage
Functional extra-low voltage (FELV) allows circuits with a rated voltage of up
to 50 V AC or 120 V DC to be operated. It does not, however, meet the
requirements of safety extra-low voltage and is therefore subject to addi-
tional conditions. FELV is implemented using a ground terminal.
Functional extra-low voltage helps protect devices (e.g. programmable con-
trollers).
PELV PELV (protective extra-low voltage) has the same requirements as safety
extra-low voltage, except for the fact that the circuit and/or exposed conduc-
tive part is/are grounded (so it is basically grounded SELV).

3.2.2 Short-circuit protection for SIRIUS contactors
Section 3.7, "Technical specifications", has information on short-circuit pro-
tection. Fuses and circuit breakers can be used as short-circuit protective
devices for the contactors.
The test criteria that apply in this case are stipulated by EN 60 947-4-1
(VDE 0660 Part 102).
Coordination types Two types of assignment are defined in the standards that correspond to
two different levels of damage.
The following applies to both types of assignment:
In the event of a short-circuit, the short-circuit protective device used must
be able to disconnect the overcurrent that occurs. Persons or other parts of
the system must not be put at risk.
Coordination type 1 The load feeder (e.g. motor starter) can be inoperable after each short-cir-
cuit. Damage to the contactor and the overload relay is permissible and it is
only possible to continue operation after defective devices have been
repaired or replaced.
Coordination type 2 After a short-circuit, there must be no damage to the load feeder devices.
However, the contactor contacts can weld if they can be easily separated
again without distorting the contact pieces.
"weld free" There is information in the catalog, for weld free protection of the contac-
tors that needs to be taken into account.
Contactors with
overload relay
If contactors are combined with an overload relay, a smaller fuse should be
used as specified in the controls catalog for permissible short-circuit protec-
tion fuses for motor starters.
