FN3-12KV 11KV Air Insulated Load Break Switch indoor Pole Mounted with Fuse
1.FN3-12KV 11KV Air Insulated Load Break Switch
FN3-12 series indoor high voltage AC load switch for AC 50Hz, 10kV network, as the breaking and closing load current,also for breaking and closing load long-distance lines, capacitor bank capacitance current, load switch with fuse (FN3-12R,FN3-12R / S) can be cut short-circuit current, for protection switching purposes.The load switch can be equipped with CS3 and CS2 type manual operating mechanism.
FN3-12 type indoor high voltage AC load switch within the general shape is similar to indoor AC high voltage isolation switch, the switch to the bottom of the frame, the transmission mechanism mounted therein.
