Tab. 6/2: Rating data of the 3NJ4 cable feeders
General cubicle characteristics
Tab. 6/1 summarizes the general cubicle characteristics.
The switch-disconnectors are fixed-mounted on the hori-
zontal busbar system. Cable connection is effected directly
on the device front. The maximum cable cross sections that
can be connected are stated in the device catalogue. The
cables can be led into the cubicle from top or bottom.
The switch-disconnectors can be equipped with up to three
current transformers to enable feeder-related measure-
ments. In order to implement cubicle-related summation
current measurements, the system provides the option to
install current transformers in the busbar system.
Rating data of the cable feeders
Tab. 6/2 states the space requirements and the respective
rated current dependent on the in-line unit type.
