The development of a power distribution concept
which includes the dimensioning of systems and
plant components necessitates a coordination of the
requirements and feasibilities of both the end user
and the manufacturer. We have therefore prepared
this planning manual for the SIVACON® 8PV low-volt-
age switchboard to support you with this task.

SIVACON 8PV – for the process industry
The type-tested SIVACON 8PV switchgear and controlgear
assembly is, for example, employed in the power, chemi-
cal and mineral oil as well as in the capital goods indus-
tries. This assembly is characterized by a high degree of
availability combined with a high level of personnel and
plant safety and can be used for all applications up to
6,300 A.
SIVACON 8PS – for power distribution
With the SIVACON 8PS busbar trunking system, all load re-
quirements can be reliably and safely satisfied – from
transformers to main distribution boards and small loads –
by a total of six available type-tested systems. These bus-
bar trunking systems are characterized by their high short-
circuit strength and minimum combustive energy and can
be used for all applications up to 6,300 A.
SIVACON 8PT – for the infrastructure
The type-tested SIVACON 8PT switchgear and controlgear
assembly is not only employed for the infrastructural sup-
ply in industrial and building applications (administration,
functional as well as industrial and commercial buildings),
but is also used in the process industry. Matched to the
global market requirements, SIVACON both meets the de-
mand for standard solutions from a single source, as well
as that for local production. This assembly can be used for
all applications up to 7,400 A.

SIVACON 8PV
The Variable Low-Voltage Switchboard
Introduction
Economical, demand-oriented and type-tested (TTA) –
those are the characteristics of the low-voltage switch-
board made by Siemens. SIVACON 8PV is applicable on all
performance levels: From 6,300 A power centers to main
and sub-distribution boards, down to motor control cen-
ters – both in fixed-mounted and plug-in, as well as in
withdrawable design. Thanks to the central Siemens-inter-
nal production, this type-tested switchgear and control-
gear assembly offers the excellent quality and short deliv-
ery periods of a mature series product.
Modular design
Every SIVACON 8PV switchboard is exclusively manufac-
tured from demand-oriented and series-produced mod-
ules, all of which are type-tested and of high quality. Due
to the modules’ vast combination options, each and every
requirement can be met.
Adaptations to new performance requirements can be eas-
ily and rapidly implemented by the replacement or supple-
mentation of modules. The advantages offered by this
modular concept are obvious:
Safety and quality proof for all switchboards
thanks to type test
Compliance with any requirement profile with the high
quality of series production
Easy placement of repeat orders and short delivery
periods

Display and signaling
The position at which a withdrawable unit is located is
clearly indicated by a display on the instrument panel.
Furthermore, messages such as “Feeder not available”
(AZNV), “Test” and “AZNV and test” can be received via
additional signaling switches.
The signaling switch in the compartment (S21) is an end
switch designed as an NC contact and that in the withdraw-
able unit (S20) is an end switch designed as an NO contact.
Both switches are operated via the withdrawable unit’s main
isolating contacts.

Busbar trunking connection for Siemens power distribu-
tion boards
Connection to the Siemens SIVACON 8PV power dis-
tribution board system as a type-tested low-voltage
switchgear and controlgear assembly (TTA)
in accordance with IEC / EN 60439-1 and -2
The connection of SIVACON 8PV and SIVACON 8PS busbar
trunking systems of the LD and LX series is realized via an
installed busbar trunking connector for rated currents up
to 5,000 A.
The busbar connection can both be routed from the top
as well as from the bottom and facilitates flexible wiring
options.
The factory-fitted copper plating between the point-to-
point and line trunking system guarantees a high short-
circuit strengths which is assured by means of a type test
and offers an enormous degree of safety for power trans-
mission.
Connection options
The connection system of the SIVACON 8PV is completely
accommodated in the distribution board.
For connection, special distribution terminal boxes with a
circumferential sheet collar of type LD/LX…-VEU-… are re-
quired.
Straight, angular and offset distribution terminal boxes are
available.
The connection system is flat-mounted in the
distribution board, seen from the distribution board’s
front.

Possible variants of the PROFIBUS routing in SIVACON
PROFIBUS – Baud rate limitation (500 kBaud)
The total length of the stub lines in the communication
network (all bus stub lines inside the withdrawable units)
influences the transmission rate for the PROFIBUS commu-
nication. The permissible total length of such stub lines is
exceeded with a maximum segment utilization (30 sta-
tions) and can thus lead to communication faults.
The maximum transmission rate for the PROFIBUS commu-
nication is thus limited to 500 kBaud.
The application of 1.5 Mbaud is permissible in exceptional
cases only when complying with the following conditions:
Restriction of the slave number per segment to 10–15
stations (depending on withdrawable unit size)
No employment of devices with segment monitoring
functions (special OLMs and diagnostics repeaters)
Coordination of the bus and the communication struc-
ture with Siemens A&D CD DM TPM in Leipzig

Resistance to Internal Arcs
The testing of low-voltage switchboards under internal arc
conditions is considered a special test in accordance with
IEC 61641 and VDE 0660 Part 500, Supplement 2.
With this test, the danger to which persons may be sub-
jected in cases of internal arcs are assessed.
Thanks to its testing under internal arc conditions,
SIVACON offers the proof of operator safety with the be-
low-stated assessment criteria as a standard.
Assessment criteria
1. Properly secured doors, covers, etc., must not open.
2. Parts which may pose risks must not fly off.
3. No holes must form in the freely accessible outer parts
of the enclosure (casing).
4. No vertically attached indicators must inflame.
5. The protective conductor circuit for touchable parts of
the enclosure must remain functioning.
Grading for fault limitation
The top priority is the attempt to prevent the formation of
internal arcs completely. All quality assurance measures
serve this attempt. These measures start with the develop-
ment of the system components, which is accompanied by
numerous type tests, and furthermore comprise the switch-
boards’ correct configuration following order placement as
well as routine tests in our production units. A clearly de-
fined module structure and DP-supported configuration, or-
dering and handling procedures form the basis for configu-
ration.
For SIVACON, a graded concept was developed by
Siemens. Step 1 starts with a very high degree of operator
safety without an extensive limitation of the internal arc
effects within the system. Step 2 furthermore limits the
damage to the system’s cubicle. In the third and fourth
step, the effects on the function compartment or the in-
ternal arc's point of origin are limited, for example, to the
busbar compartment, device compartment, withdrawable
unit or connection compartment.
This facilitates the system's flexible and cost-effective ad-
justment to the actual requirements of the operator.

TTA – PTTA
The application of other switchgear and controlgear and pro-
tective devices is only permissible if their technical data are
at least identical or better (conclusion by analogy).
Partially type-tested assembly (PTTA)
These assemblies contain both type-tested as well as non-
type-tested components. Non-type-tested components
must be derived from type-tested components.
With type-tested assemblies, all proofs must be
established by means of tests.
With partially type-tested assemblies, two exceptions are
permissible (refer to the table):
1. Proof of compliance with the limit overtemperatures.
With switchboards with a supply current strength up to
max. 3,150 A, the proof can also be provided by means
of extrapolation.
2. The short-circuit strength proof is not required for
switchboards which are protected by a current-limiting
protective organ whose let-through current amounts to
≤ 15 kA.
If an extrapolation or calculation in accordance with DIN
VDE 0660 Part 500, is required, this must always be based
on a derivation of type-tested systems.
Only if all required proofs could be clearly established,
may switchgear and controlgear assemblies be desig-
nated as type-tested switchgear and controlgear as-
semblies (TTA) or partially type-tested switchgear and
controlgear assemblies (PTTA). These combinations
thus comply with the applicable safety regulations.
The safety standard for low-voltage switchgear
and controlgear assemblies
The requirements placed upon low-voltage switchboards
with regard to heat dissipation, high packing density,
short-circuit current capacity and insulation resistance
have increased over the past years.
The safe operation of a low-voltage switchboard can only
be assured if the manufacturer complies with the stan-
dards applicable to the respective switchgear and control-
gear assembly and is able to prove such compliance.
Only switchboards which correspond to the currently appli-
cable standards comply with the present safety regulations.
Applicable standards are:
IEC/EN 60439-1, VDE 0660 Part 500
Low-voltage switchgear and controlgear assemblies
Type-tested and partially type-tested assemblies
These standards have identical contents. They show
two possibilities in accordance to which low-voltage
switchboards may be manufactured:
Type-tested switchgear and controlgear assembly (TTA)
Partially type-tested switchgear and controlgear assem-
bly (PTTA)
Type-tested assembly (TTA)
In these assemblies, all components have been type-tested
both individually as well as in the assembled form, includ-
ing all electrical and mechanical connections.

Environmental class IR 2 (indoor room 2):
Indoor rooms in buildings with minor heat insulation or a
low heat capacity, heated or cooled, without temperature
monitoring. The heating or cooling may fail for several
days, e.g. unattended relay, amplifying and transformer
stations, stables, motor vehicle repair shops, fabrication
rooms for unfinished goods, hangars.
Environmental class IR 3 (indoor room 3):
Indoor rooms in buildings without noteworthy heat insula-
tion and a low heat capacity, neither heated nor cooled,
also in warm and humid areas, e.g. workshops, telephone
booths, building entrances, barns, attics, unheated stor-
age rooms, sheds, garages, network stations.
Environmental conditions for switchboards
The outside climate and the external environmental condi-
tions (natural foreign matters, chemical active harmful
substances, small animals) may have varyingly strong in-
fluences on switchboards. The influence depends on the
air-conditioning equipment of the switchboard room.
Necessary additional protective measures for the switch-
board therefore depend on the resulting indoor room cli-
mates, which are divided into three environmental classes:
Environmental class IR 1 (indoor room 1):
Indoor rooms in buildings with a sound heat insulation
or a high heat capacity, heated or cooled, normally only
subjected to temperature monitoring, e.g. normal residen-
tial rooms, offices, shops, transmission and switching cen-
ters, storage rooms for sensitive goods.

Rated impulse withstand voltage (Uimp)
IEC/ EN 60947-1; 4.3.1.3
Parameter for the resistance of clearances inside
switchgear and controlgear to impulse overvoltages. The
application of suitable switchgear and controlgear pre-
vents disconnected system parts from transmitting over-
voltages from the network in which they are applied.
Rated current (In) (of circuit-breakers)
IEC/ EN 60947-2; 4.3.2.3
Current which, for circuit-breakers, corresponds to the
rated continuous current and the conventional thermal
current.
➔Rated continuous current
Rated control voltage (Uc)
IEC/ EN 60947-1; 4.5.1
Voltage applied to the actuating NO contact of a control
circuit. It may deviate from the rated control supply volt-
age if transformers or resistors are connected to the con-
trol circuit.
Rated ultimate short-circuit breaking capacity (Icu)
IEC/ EN 60947-2; 4.3.5.2.1
Maximum short-circuit current which can be interrupted
by a circuit-breaker (test O – CO). After a short-circuit re-
lease, the circuit-breaker is able to trip with increased tol-
erances in the case of overload.
Rated service short-circuit breaking capacity (Ics)
IEC/ EN 60947-2; 4.3.5.2.2
The short-circuit current depending on the rated opera-
tional voltage which can be repeatedly interrupted by a
circuit-breaker (test O – CO – CO).
After the short-circuit breaking, the circuit-breaker is able
to continue to carry the rated current in the case of in-
creased self-heating or overload.

Rated operational voltage
Rated Values / Definitions
Rated values
In accordance with IEC/EN 60439-1, the manufacturers of
low-voltage switchgear and controlgear assemblies state
rated values. These rated values apply to the specified op-
erating conditions and characterize the usability of
switchgear and controlgear assemblies. The coordination
of the operating equipment or the configuration of the
switchgear and controlgear assemblies must be based on
these rated values.
Rated short-time withstand current (Icw)
IEC/ EN 60439-1; 4.3
As the effective short-circuit current value, the rated short-
time withstand current characterizes the thermal strength
of switchgear and controlgear assembly circuits during a
short-time load. The rated short-time withstand current is
normally determined for the duration of 1 s; deviating
time values must be stated.
The rated short-time withstand current is stated for the
distribution and/or main busbars of switchgear and con-
trolgear assemblies.
Rated peak withstand current (Ipk)
IEC/ EN 60439-1; 4.4
As peak value of the peak current, the rated peak with-
stand current characterizes the dynamic strength of
switchgear and controlgear assembly circuits. The rated
peak withstand current is normally stated for the distribu-
tion and/or main busbars of switchgear and controlgear
assemblies.
Rated conditional short-circuit current (Icc)
IEC/ EN 60439-1; 4.5
The rated conditional short-circuit current corresponds to
the uninfluenced short-circuit current which switchgear
and controlgear assembly circuits that are protected by
short-circuit protective devices may carry without damage
(for a limited time). The rated conditional short-circuit cur-
rent is therefore stated for outgoing and/or incoming feed-
ers, e.g. with circuit-breakers.

Rated operating capacity
IEC/ EN 60947-1; 4.3.2.3
Capacity which can be switched by switchgear and con-
trolgear with the assigned rated operational voltage in ac-
cordance with the utilization category, e.g. power contac-
tor of utilization category AC-3: 37 kW at 400 V.
Rated operational voltage (Ue)
IEC/ EN 60947-1; 4.3.1.1
Voltage to which the characteristic values of switchgear
and controlgear are referred to. The maximum rated oper-
ational voltage must, in no case, exceed the rated insula-
tion voltage.
➔Rated insulation voltage
Rated operational current (Ie)
IEC/ EN 60947-1; 4.3.2.3

Reactive Power Compensation
Calculative determination and specification of the
required capacitor power
1. The electricity bill of the power supply company shows
the consumption of active power in kWh and of reac-
tive power in kvarh; the power supply company de-
mands a cos ϕof 0.9 ... 0.95; the reactive power de-
mand should be compensated to a value approximat-
ing cos ϕ= 1 for cost optimization.
Determination of tan ϕ1= Reactive power = kvarh
Active power kWh
2. The table shows conversion factor “F”, which must be
multiplied with the average power consumption Pm.
With tan ϕ1cos ϕ1shows the power factor prior to
compensation, while cos ϕ2shows the desired power
factor for compensation with factor “F”.
3. The required compensation power is stated in kvar.
Example:
Reactive power Wr= 19,000 kvar/month
Active power Wa= 16,660 kWh/month
Average power consumption
Active power =16,660 kWh = 92.6 kW
Operating time 180 h
tan ϕ1= Active power = 19,000 kWh = 1.14
Operating time 16,660 kWh
Power factor cos ϕ1= 0.66 (with tan ϕ1= 1.14)
Power factor cos ϕ2= 0.95 (desired)
Conversion factor “F” = 0.81 (from tan ϕ1and cos ϕ2)
Compensation power = Average power x factor “F”
= 92.6 kW x 0.81
Required compensation power: 75 kvar
