Fitting tap-off units to plug-in (125 - 630 A)
The installation of units for plug-in is only possible on straight busbar elements
with plug-in.

These tap-off units can be installed without switching off the busbar trunking
run. The measures for live working according to EN 50110 (VDE 0105-1) and
national regulations and standards must be observed for this (national
regulations may also prohibit live assembly).

The tap-off units are plugged onto the plug-in and clamped to the straight
busbar element.
-
Due to the large connection compartment, the maximum rated current is
restricted according to the number of plug-in on the busbar elements
-
to a maximum of 250 A for 3 plug-in,
-
to 630 A for 2 plug-in,
