12kV air load break switch
Air Insulated Load Break Switch Air Break Switch FN12-12
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.
