Product Description

Product Description

 

FKN12-12 indoor high-voltage compressed gas load switch (hereinafter referred to as FKN12-12 load switch) is a three-phase high-voltage switchgear with a rated voltage of 12kV and a rated frequency of 50Hz, which is used to separate load current, closed-loop current, no-load transformer and current charging current, and close short-circuit current. A load switch equipped with a grounding switch can withstand short-circuit currents.
FKRN12-12 indoor high-voltage load switch fuse combination electrical appliance (hereinafter referred to as FKRN12-12 combination electrical appliance) is an indoor switchgear combined with FKN12-12 load switch and S  LAJ-12 (XRNT  -10) high-voltage current limiting fuse.
 It can reliably cut off any current up to the short-circuit current; The load switch breaks the current, the fuse breaks the short-circuit current,and the joint interrupts any current between the working current and the full short-circuit current, while the fuse opens the load switch through its impactor.
