Main technical parameters:
FN12-12 and FN12-12R is of three phases indoor use AC high voltage load switch for breaking and making the circuit of 50Hz, 12KV system under rated loading, closed loop current, no-loading transformer, cable charged current and short circuit current. The load switch equipped with earth switch can withstand short circuit current, and m-ainly used in power distribution substation and industrial electrical equipment where three phase closed loop circuit or bottom power supply system for control and protection.
