FN12 10kv Air Load Break Switch


1250A Air Load Break Switch


XG FN12 Air Load Break Switch

Product Description

1. FN12 type indoor 10kv 11kv 12kv 630A Air load break switch


It is a three phase H.V. switch equipment of 12KV, 50Hz for breaking or closing load current., no-load transformer cable charging current and closing short-circuit current. The load switch with earth switch can bear short-circuit current.

It is made up of FN12-12D load switch and S()LAJ-12(XRNT()-10) H.V. current-limiting fuse box. It can break any current, load switch breaking working current and fuse box breaking short-circuit current, jointly breaking any current between short-circuit current. Meantime, fuse box make the switch off of with the striker.
