INDOOR HIGH-PRESSURE COMPRESSED
GAS LOAD BREAK SWITCH

Overview
FKN12-12 indoor high-pressure compressed-type load break 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. It is used for switching load current, closed-loop current, no-load transformer
and current Charging current, closing short circuit current. The load switch equipped with a grounding switch can withstand short-circuit current.
FKRN12-12 indoor high-voltage load switch fuse combination electrical appliance (referred to as FKRN12-12 combined electrical appliance above) is
an indoor switchgear combining FKN12-12 load switch and SKLAJ-12 (XRNTC1-10) high-voltage current-limiting fuse . It can reliably break any current
up to the short-circuit current; the load switch breaks the current, the fuse breaks the short-circuit current, and jointly breaks any current between the
working current and the full short-circuit current, and the fuse makes the load switch through its impactor Open.
