Busbar Systems
General data
■ Overview
The use of busbar systems with their versatile rail-adaptable
connection, switching and installation devices is an ideal and
cost-effective electrotechnical enhancement of modern distribu-
tion boards due to their small footprint, compact design and
quick assembly contacts. Mounting is implemented on longitudinal stays. The busbar spacing is 60 mm.

■ Design
Notable cost reduction compared to conventional installation in
switchgear and control cabinets due to the following reasons:
• Mechanical fixing and electrical contacting in a single step
• No access wiring and fewer busbar terminals used
• Double use of the busbar space
• Clear arrangement
• Straightforward replacement of individual devices or whole
combinations
• High operational safety through finger-safe cover of the
adapters and device holders
8US busbar systems with 60 mm busbar center-to-center
spacing as well as flat copper profiles have become firmly
established on the world market.
All the above advantages are felt especially in cases where
many tap-off units of the same performance range are required.
The busbar runs prove most advantageous when the infeed is
centrally located and the load is distributed symmetrically on
both sides.
■ Application
8US busbar systems are used for the direct busbar-mounting of
current-limiting devices (protective devices) such as fuse switch
disconnectors and circuit breakers as well as complete load
feeders.
8US busbar systems are designed for horizontal mounting of the
busbars.
The permissible busbar temperature is decisive when dimensioning the busbars. The busbar temperature is dependent on
the current and the current distribution, on the busbar cross-section and the busbar surface, on the position of the busbars, convection and the ambient temperature. The values stated in the
following table can only be considered as guide values because
the conditions vary with each location. The values are based on
continuous current over the whole busbar length.
■ Function
Short-circuit strength
The short-circuit strength of the busbar system is dependent on
the distance of the busbar supports and on the busbar crosssection.
The short-circuit strength of the whole system is dependent on
the short-circuit strength of the busbars and of the adapters with
circuit breakers or switch disconnectors. If one of these values
is lower than the prospective short-circuit current at the installation site, a current-limiting protective device has to be mounted
upstream of the 8US busbar system. This may also be mounted
as a feeder circuit breaker on the busbar system itself.

Take care when machining that no cracks are formed. A cross-cut circular saw with the
following characteristic values has proven successful in cutting cover profiles for busbars:
Machining of plastic profiles
• D = 300 mm, B = 2.2 mm,
• T = 120 R (5° negative replaceable tooth at a cutting rate of 50 ... 60 m/s)
• Tooth feed 0.05 ... 0.1 mm
The plastic parts are secured so that vibration is ruled out.

Current carrying capacity of the terminal points
The specified current carrying capacities reflect the
thermal load capability of the terminal points under
favorable conditions (with the largest conductors it is
possible to connect). This does not invalidate the assignment of conductor cross-sections and current carrying
capacities as defined in national and international specifications.

Example
1,8
Under normal operating conditions (35°C ambient temperature
and 65°C bar temperature), a 30 x10 mm busbar can handle
loads up to 630 A. However, you want the busbar to handle a
higher current, at the expense of an increased busbar temperature of max. 85 °C.
1,7
The following applies:
• Bar type: Busbar
• Busbar size: 30 x 10
• Max. bar temperature: 85 °C
• Ambient temperature: 35 °C

The figure on the right shows the correction factor k2 = 1.3 for the
current-carrying capacity.
0,7
This results in a higher value of 630 A * 1.3 = 819 A.
0,5
If the 30 x10 busbar is to be operated with a bar temperature of
85°C, it may be loaded with maximum 819 A.

If a higher bar temperature than 65°C is possible, the busbars
can be operated with higher current values according to the
following formula: I = In * k2

According to DIN 43671, current-carrying capacity values for flat
bars are defined as 35 °C ambient temperature and 65 °C busbar temperature

8US 60 mm Busbar Systems
Introduction
■ Overview
The 60 mm busbar system for the medium and top performance range up to 1600 A, here for example with the 3NP1 switch disconnector, size 3
The 60 mm busbar system is used preferably in control cabinet
installation, in motor control centers and in power distribution
systems of the medium power range (630 A) and top performance range (1600 A, special profile).
The 60 mm busbar system can be configured as a basic system
without covers. The busbar cross-sections are available in the
sizes 12 x 5 mm to 30 x 10 mm and as a special profile.
Busbar adapters for SIRIUS, 3VL circuit breakers, 3KA and 3KL
switch disconnectors, and 3NP1 and 3NP5 fuse switch disconnectors offer numerous options for configuring this busbar system. Infeed units, terminals and other accessories open up a
large range of applications.
Busbars with a special profile are suitable for applications up to
1600 A. All components of the 60 mm busbar system can be
fitted.
SIRIUS motor starter combinations
SIRIUS motor starter combinations can be configured with and
without fuses.
The compact 3NW7 ... -1 cylindrical fuse holders for IEC fuses,
size 10x38 mm, or 3NW7... -1HG UL for Class CC fuses are
suitable for use with fused motor starter combinations.
With a width of 45 mm, SIRIUS motor starter combinations are
the same width as the majority of contactors.
For further information and accessories, see chapter 5,
"Fuse Systems" ➞ Cylindrical fuse systems
➞ Fuse holders in size 10x38 mm and Class CC.

Busbar Systems
8US 60 mm Busbar Systems
UL applications
■ Overview
Short-circuit strength
The short-circuit strength of the busbar system is dependent on
the distance of the busbar supports and on the busbar crosssection.
The short-circuit strength of the whole system is dependent on
the short-circuit strength of the busbars and of the adapters with
circuit breakers or switch disconnectors. If one of these values
is lower than the prospective short-circuit current at the installation site, a current-limiting protective device has to be mounted
upstream of the 8US busbar system. This may also be mounted
as a feeder circuit breaker on the busbar system itself. The table
below provides a selection aid for this purpose.

Busbar Systems
Distribution board components
■ Overview
Material properties
Ambient temperatures
Busbar supports and bus-mounting fuse bases (see "Built-in
components" from page 31) are manufactured from glass-fiber
reinforced, thermoplastic polyester (color RAL 7035, light gray).
The material ensures excellent mechanical, chemical and
electrical properties. Furthermore, the material has an extremely
low flammability and meets the requirements of UL 94 V0. This
satisfies the load requirements of the busbar supports at rated
operational voltage 500 V and rated currents at 200 A to 630 A,
as well as the rated short-circuit strength 50 kA.
When dimensioning the busbars based on rated currents, the
ambient temperature and the Cu busbar temperature must also
be taken into account.
The location of the busbar system and its ability to dissipate heat
through convection also play a key role in this calculation.
Because conditions can vary for each distribution board, the
values in the following table serve as a guideline only. However,
they must be applied to the entire busbar length.

As far as other types of upstream protective devices are concerned, please observe the permissible continuous current of the busbar.
Dynamic rated short-circuit strength
The electrodynamic load of the busbars depends on the level of
short-circuit current, the length of the busbar section through
which the current flows, the support spacing of the busbar supports and, of course, on the distance between the busbars themselves. This is because, for example, if an LV HRC fuse is connected upstream to the busbars in the protective device, the letthrough current iD is the maximum current to flow through this
protective device. The value iD depends on the maximum system short-circuit current and the current-limiting action of the
protective device used. The permissible let-through values of
the protective devices are specified by the manufacturers in the
form of a current limitation diagram as a function of the so-called
prospective short-circuit current (r.m.s. value of the possible
rated short-circuit current for the system).

It is essential to ensure that the permissible current carrying
capacity of the individual busbars is not exceeded. A center
infeed is required in the limit range. However, the infeed can also
be carried out at both ends of the busbar.

The current-limiting characteristics for the fuse links can be
found in the Technical Information, see note on Technical
Information at the beginning of the chapter.
For busbar supports with busbars of 12 mm x 5 mm to
20 mm x 5 mm, the distance between the holders of the support
spacing should be adapted to suit the bars in the distribution
board and, if possible, should not exceed 250 mm. When using
busbars of 25 mm x 5 mm, 30 mm x 5 mm, 12 mm x 10 mm to
30 mm x 10 mm the distance can also be up to 500 mm. In the
case of larger distances, subcarriers must be fitted, as increased support spacing reduces the dynamic stability.

Built-in components
■ Overview
Rail-adaptable built-in components, such as NEOZED and
DIAZED bus-mounting bases, adapters for modular installation
devices, fuse switch disconnectors and NEOZED bus-mounting
fuse switch disconnectors are made of glass-fiber reinforced,
thermoplastic polyester. The material ensures the required
mechanical, chemical and electrical properties.
have integrated reach-through guards, enable the implementation of cost-effective overall solutions.
Efficient power distribution up to 630 A.
Users have several options for mounting the SR60 busbar
system:
Higher overall efficiency and cost savings in the plant
engineering industry.
1. Mounting in distribution boards
The busbar supports are mounted on the longitudinal stays.
Once the built-in components are mounted and connected, the
touch protection cover (section cover) protects against accidental contact with live parts.
2. Installation in industrial control cabinets
The demand for comprehensive touch protection has generated
new solutions: built-in components, such as busbar fuse bases
Previously two optional solutions were provided, which can now
be replaced using new technology: touch protection over base
and edges or touch protection over partitions.
The fuse holders for cylindrical fuses, size 10 x 38 and for
American fuses, Class CC, can be used in the international plant
engineering industry. In addition, Siemens offers a broad range
of UL-approved components for the design of switchgear
assembly according to UL 508 A.
For further information, see chapter "BETA Devices according to
UL Standards" in Catalog LV 16 · 2009.
Fuse holders are available with a connection module 16 mm²
and screwless terminals; this offers users maximum safety and
comfort.

■ Benefits
• The direct contact of the rail-adaptable switching and installation devices on the Cu busbars reduces distribution panels
and mounting times
• Compared to conventional installation, the transfer resistance
of the connections is drastically reduced This prevents unnecessary temperature rise.
• New built-in components with touch protection ensure comprehensive touch protection without the previously required
partitions.
• International application due to UL-approved components.
• Enhanced effectiveness and increased safety due to
screwless terminals.
