Under-pavement Disconnection Box |
|
Type BC 9001 for LV distribution network |
|
Installed on a three-phase low voltage underground distribution network, this disconnection box allows every combination of incoming-outgoing cables in 4 directions.
Can be handled under voltage and on charge, with test possibility, short-circuiting and earthing the directions, the operation of this box can be carried out in complete safety because the active parts are never visible.
Its compact size and shape makes it an attractive product, both in its installation and operation, in all places where the environment does not allow an above-ground disconnection box (pedestrian areas, listed buildings, vandalism
).
