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.
