3.4 Cubicles for direct supply and
direct feeder
The different cubicle types:
1. Top busbar position, cable entry from the bottom or top
(the position of the connecting bars is identical for cable
entry from the top or bottom)
2. Rear top busbar position, cable entry from the top
3. Rear top busbar position, cable entry from the bottom
4. Rear bottom busbar position, cable entry from the top
5. Rear bottom busbar position, cable entry from the
bottom
are schematized in Fig. 3/3.
The cubicle width and maximum number of cables which
can be connected depend on the rated current (Tab. 3/13
and Tab. 3/14). The rated currents, in turn, depend on the
busbar position and cable entry (Tab. 3/15).

cable lugs with an M12 screw is possible. However, this cable lug is not in compliance with DIN 46235, although it is
available at some manufacturers
The number of connectible cables may be restricted by the available roof/floor panel openings and/or door installations.
The position of the connection busbars is identical for front or rear connection in the cubicle.
