General

FN12-12D/630-20 indoor AC high voltage load switch(Hereinafter clled FNI2-12D load switch is is suitable for three-phase AC distribution system with rated voltage of 12 KV and rated frequency of 5OHz. It is used for opening and closing load current, closed loop current, no-loa transformer and cable charging current, closing short circuit current. The load switch equipped with the earthing switch can withstand the shor circuit current.

FNI2-12IR)D/25-31.5 indoor AC high voltage load switch–fuse combination (hereinafter called FN12-12IRJD combination) is an indoor high voltage switch device which combines FNI2-12D load switch and S□LAJ-12(XRNT□-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 breal the load switch through its impactor.
