FKN12-12/FKRN12-12D Indoor High Voltage Gas Pressure Load Switch

FKN12-12/FKRN12-12D Indoor High Voltage Gas Pressure Load SwitchFN12-12D/630-20 indoor AC high voltage load switch(Hereinafter called FN12-12D load switch) is is suitable for three-phase AC distribution system with rated voltage of 12 KV and rated frequency of 50Hz. It is used for opening and closing load current, closed loop current, no-load transformer and cable charging current, closing short circuit current. The load switch equipped with the earthing switch can withstand the short circuit current.

FN12-12(R)D/125-31.5 indoor AC high voltage load switch—fuse combination (hereinafter called FN12-12(R)D combination) is an indoor high voltage switch device which combines FN12-12D load switch and SDLAJ-12(XRNTn-10)high voltage current limiting fuse. It can break reliably under any current except it is up to short-circuit current.
