FN7-12 INDOOR HIGH VOLTAGE LOAD BREAK SWITCH WITH FUSE 11KV LOAD BREAK SWITCH
FN7-12DR is used in three-phase AC power network of AC 50Hz, rated voltage 12KV for breaking load current
and controlling short-circuit current.
FN7(C)-12 type H.V. load switch and fuse box is based on the FN7-12 series H.V. load switch with operating
mechanism, make the installation more simpler, can meet orders needs
