The LI busbar trunking system is a design verified
low-voltage assembly in accordance with IEC 61439-1/-6
in the form of an aluminium enclosed sandwich system.
The LI sandwich system consists of busbars, insulation,
the aluminium housing and the fastening and
connection elements.
Power distribution
The main application of busbar trunking systems is
power distribution. The advantage of such systems over
cable installations is that the locations of power tap-off
units are not permanent but can be moved to any
position within the entire system. To tap power at any
given point simply requires positioning a tap-off unit at
that location on the busbar.
The result is a flexible distribution system for decentralized
power supply to a particular line or area. Tap-off points
can be located on one or both sides of the straight
trunking units.
The LI busbar trunking system provides tap-off units
from 50A to 1250A for power tap-offs and for
connecting consumers, providing the power supply for
consumers in the range between 10kW and over 400kW.
Tap-off units can be fitted with either fuse switches or
circuit-breakers.
With all busbar trunking systems, plug-on/-off tap-off
units have a high safety standard. The following
requirements will be fulfilled by all tap-off units:
- Early-make PE contact for mounting and late-break
contact for removing
- The tap-off point is designed with IP2X protection.
Mounting should only be possible in the correct phase
sequence.
- Tap-off unit could be locked in disconnected position

Various busbar trunking system components are
responsible for transporting power between transformers
and low-voltage power distribution systems. They are
used between the transformer and the main distribution
board and then on to the sub-distribution level.

Trunking units without tap-off points, available in
standard lengths, are used for transporting power. In
addition to the standard lengths, customers can select
lengths from several ranges to meet their particular
building requirements.

System overview | System selection criteria
System selection criteria
electromagnetic fields and system harmonics influence
the functional capability of computers, servers and
other electronic devices. The large number of these AC
loads within a network places a high load on the neutral
conductor through harmonics. Double neutral
conductor cross-sections (200%) reduce the plant's
susceptibility to interference in networks subject to
harmonics.
Conductor configurations
IEC 364 stipulates that electrical equipment must be
selected according to the type of the system at hand in
order to determine the protective measures required.
For the LI system this selection is based on the
appropriate conductor configuration.

1) Can be realised by using the combination of trunking unit LI with PEN conductor
(3PH-PEN) and tap-off units with N and PE conductor (3PH-N-PE)
2) Each conductor configuration contains an additional busbar as PE conductor

The growth in the number of new electronic and
noise-sensitive loads, especially in the area of energy
supply in buildings, presents new challenges to busbar
trunking systems. Disturbance variables such as
Conductor configurations
The LI busbar system is available with six different conductor configurations depending on the system type, the
size of the N and PE cross-sections, as well as whether or not an additional insulated PE conductor (Clean Earth) has
been included.

The Ll system is a future-proof investment due to its flexibility in load change and integration into energy
management systems. A reliable and flexible system that is safe for people and plant, and highly efficient
from planning via installation to operation.
Clean Earth
Isolated PE conductors are fully galvanically isolated
from the trunking housing. In this way, the
conductors make a crucial contribution to the
reliability and safety of the energy supply for
electronic loads in buildings. In the case of a
short-circuit between phase and housing, this PE
conductor (clean earth) remains unaffected by this
fault. This means it is non-isolated in the event of a
short-circuit to frame. Even the fault currents in the
housing generated by magnetic fields do not affect
the clean earth. This means the clean earth is
optimally suited to PE connection of sensitive
electronic loads.

Advantages of the LI system
PE conductor cross-section
A high cross-section of the PE conductor also offers
safety for the energy supply. It guarantees early
shutdown of small short-circuit currents thanks to low
loop impedances. This reduces the risk of potential
downtime resulting from fast shutdown of the
upstream protective elements.

large distances with low voltage drops, thanks to its
sandwich design. Junction units like knees and elbows
for changing directions into vertical and horizontal run
positions serve perfectly to various building structures.

Cable entry to tap-off units
Cable entry is possible from the side or from the end. The
basic tap-off units are designed with blind plates where
cable glands are supplied locally. As an accessory, cable
entry plates with fitted cable grommets are available for
multi-core and single-core cables.
Power distribution
Safe, flexible, and future-proof solution
Power distribution is the main application of busbar trunking systems. The advantage of such
systems over cable installations is a high degree of flexibility allowing easy modifications in the
future.
The LI system is the right solution where power distribution has to be flexibly implemented with
horizontal and vertical busbar runs. Furthermore, its modular tap-off units allow to suit various
applications. For easy integration into an energy management system, measuring devices can
be built into tap-off units for a future-proof solution.
Modular tap-off units
Busbar trunking systems provide flexible power
distribution via plug-on/-off tap-off units along the entire
LI run. If there are changes of location or modifications
of the load, the power supply can be easily adapted –
without downtime.
Power can be tapped at any given point by simply
positioning a tap-off unit at the required location on the
busbar. Tap-off units can be mounted on one or both
sides of straight trunking units.
The result is a flexible distribution system for
decentralised power supply to a particular line or area.
Tap-off units are available from 50 A to 1250 A for load
connections. They can be equipped with fuse switch
disconnectors, switch disconnectors with fuses, fuse
bases1) (LV HRC), or circuit breakers.
Safe in installation and operation
• Guided plugging with a plug-on/-off facility on the tap-off
point avoids incorrect fitting, ensures IP2X and IPXXB during
tap-off unit is disconnected or connected
• Leading PE contact ensures a protective conductor connection
during assembly or disassembly
• Isolation of tap-off units during removal is assured by a
compulsory sequence of operations
• Quick and easy modifications or expansions with plug-on/-off
tap-off units (up to 1250 A) on energised2) runs
• Contact device section in the front of the tap-off unit is
“finger-proof”
the plugging process, and indicates unambiguously if the
1) Version with NH fuse base cannot be plugged on energized LI runs
2) In accordance with EN 50110-1 (VDE 0105-1); please always observe national regulations/standards
Tap-off units with fuse-type protection and switching
devices are available up to 630 A, with circuit breakers
up to 1250 A.
The tap-off units can be used in a wide range of grid
types. For conductor configurations with 200% N, tap-off
units offer a double N connector as well as Clean Earth
with a separate PE connection insulated to the housing.
Rugged tap-off unit housings ensure IP55 protection
irrespective of the mounting position. The rated
operational voltage (Ue) is up to 500 V for circuit
breakers and 690 V for NH fuses.
Future-proof system
When energy data for transparent power flows or remote
switching and monitoring are required, the LI system
offers integrated and communication-capable switching
and measuring devices as well as components for
optimum energy management (including communication
capabilities for Modbus TCP, PROFIBUS and PROFINET).

The trunking units are interconnected
through a hook-and-bolt technology.
In this way, there is only one single
transition for each electrical conductor,
ensuring a large-surface contact for an
outstanding connection quality and
durable electrical contact at the same
time.
When the necessary clamping pressure
is reached, the outer nut head is
Step 1
automatically sheared off. This gives
simple and instant confirmation of
correct assembly.
After tightening the hook and bolt
connection, the clamping point is
covered with a connection flange. The
side protection cover can only be fitted
once the outer nut head has sheared
off (see figure Step 2).
Upon completion of the hook and bolt
connection, the trunking unit connection
fulfils the high degree of protection P66.

Further Information | Installation recommendation
Further Information | Fire barrier
Fire barrier
Necessary wall or ceiling cutout
Built-in prevention for a safe infrastructure
Fire barrier tested in accordance with EN 1366-3 standard for safe
and reliable installation in risers and across electrical rooms
International building regulations prescribe that buildings must be designed in such a way that "fire and smoke are
prevented from starting and spreading and that, if there is a fire, effective fire fighting and the saving of human and
animal life is possible". This means that no fire or fumes are permitted to spread from one floor or fire section to
another.
All LI busbar trunking systems can be equipped with a fire barrier. Thus, they fulfill the stipulations of EN 1366-3 (Fire
resistance tests for service installations — Part 3: Penetration seals). The fire barrier is delivered as a stand-alone type for
customer assembly, with the fire resistance classes El 90 and El 120.
European standards
Test standard
EN 1366-3 (Fire resistance tests for service installations - Part 3: Penetration seals). With this standard the requirements
for fire resistance 120 min according to ISO 834 as stated in IEC/EN 61439-6 are fulfilled.
Classification standard
EN 13501-2 (Fire classification of construction products and building elements - Part 2: Classification using data from fire
resistance tests, excluding ventilation services)
International standards
The classification El 90 or El 120 according to EN 13501-2 of the LI fire barrier conforms to the internationally valid
standards:
• ISO 834-1: 1999 with the fire resistance time of 90 minutes or 120 minutes
• EN 61439-6 / IEC 61439-6 (Clause 10.102) for the verification of the fire resistance duration 90 minutes or 120
minutes for busbar trunking units with fire barrier

1) Consideration applies to edgewise busbars
2) Attention: When an expansion compensation or an equipotential bonding is used, the minimum distance must be
increased accordingly
The minimum lateral wall distance W1min depends on the dimensions of the selected tap-off unit
for the power distribution, and on the space requirement for installation/removal of the trunking
units and the vertical fixing brackets. The fixing screws for the vertical fixing brackets must still be
sufficiently accessible.
Fixing brackets for the LI system
Horizontal installation
Fixing of the LI system in horizontal edgewise and in
horizontal flat mounting positions is possible with:
- 5 U-profile sizes
- 2 fixing clamp units
The combination of U-profile and fixing clamps enables
optimum fixing of the LI system.
Note
As a rule, the minimum wall distance W2min is pre-defined by the dimensions of the vertical fixing
bracket. When the standard spring bracket is used, the distance W2min is set to 100mm.
Horizontal installation
Vertical installation
Special spring brackets are required for vertical installation,
in order to fix the LI run in shafts running upwards along the
wall. The spring bracket is dimensioned to carry the weight
of the busbar run for floor heights up to 4.10 m. Bigger
fixing distances up to 6 m are possible and on request.
However, the minimum wall distance W2min is also dependent on the fixing material required on
site to compensate wall unevennesses or wall inclinations. The fixing material is selected according to
the corresponding load. The standard fixing brackets can be attached directly to the wall if there are
no wall unevennesses or inclinations.
