■ Design<br />
Trunking units<br />
Connections<br />
NSV0_00045<br />
Assembly of the trunking units, also with end flanges and feeder<br />
units, is fast and inherently secure. The trunking unit or end<br />
flange is simply inserted in the lower housing of the clamp terminal.<br />
Once the upper part of the clamp terminal or feeder unit is<br />
fitted, a secure connection is established by tightening four<br />
screws. The PE path is established automatically when the<br />
enclosures are connected.<br />
An expansion compensation mechanism is built into the clamp<br />
terminal.<br />
End flanges<br />

Trunking units are available in 2 m and 3 m lengths. They consist<br />
of a galvanized metal enclosure with a light gray (RAL 7035) aluminum<br />
painted finish. They are equipped with 4 busbars for L1,<br />
L2, L3 and N (aluminum conductors; copper for <strong>160</strong> A; silverplated<br />
copper pick-up and connection contacts).<br />
The enclosure of the trunking unit also serves as PE conductor.<br />
Five current ratings are available in only one frame size: <strong>40</strong> A,<br />
63 A, 100 A, 125 A and <strong>160</strong> A.<br />
The tap-off points are spaced at regular intervals of 0.5 m or 1 m<br />
on one side. The 2 m lengths have two or four tap-off points, the<br />
3 m lengths three or six.<br />
The end flanges provide protection against direct contact at the<br />
ends of the busbar run. They are suitable for use with all<br />
systems. Two end flanges are supplied as standard with each<br />
feeder unit.<br />

The tap-off points are finger-safe. They are opened automatically<br />
by the tap-off units and close by themselves when the<br />
tap-off units are removed.<br />
The junction units, which consist of flexible conductors, are<br />
available in versions for 100 A and <strong>160</strong> A, each in 0.5 m and 1 m<br />
lengths.<br />
The flexible junction units enable the direction of the busbar run<br />
to be changed as required. The 0.5 m version is recommended<br />
for right angles, the 1 m version for fitting around obstacles or for<br />
adapting to variations in height.<br />
