Product Description
Application
FN12-12 series high voltage AC Vacuum load switch is applied in the three-phase, AC50Hz, rated voltage up to 12KV electric supplying network. Mainly applied in three-phase RMU net pr ending electric-supply city distribution station and industrial electrical equipments, with load-control and short-circuit protection.
FNR12-12 series high voltage AC Vacuum load switch is applied in the three-phase, AC50Hz, rated voltage up to 12KV electric supplying network. The load switch and combination equipments own obvious isolation fractures, can match earthing switch of CO capacity and electric spring mechanism.
Can realize remote control.
