Indoor High Voltage Gas Pressure Load Switch

© General

FN12-12D/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. The load switch breaks the working current and the fuse breaks the short circuit current. And the combination breaks any overcurrent between the working current and the full short circuit current, and the fuse breaks the load switch through its impactor.
