PRODUCT DETAILShigh voltage load switch -- fuse combination
Description: FKN12A-12D/T630-20 indoor
high voltage pneumatic load switch-fuse combination (hereinafter
referred to as FKN12A-12D load switch) is three-phase high voltage
switchgear with rated voltage of 12kV and rated frequency of 50Hz,
which is used for the separation and combination of load current,
closed-loop current, no-load transformer and cable charging
current. Turn off the short circuit current. Load switch equipped
with ground switch can withstand short circuit current.
FKRN12A-12D/T125-31.5 AC high voltage load switch-fuse combination
is indoor high voltage switchgear combined with FN12A-12D load
switch and Sport LAJ-2 (XRNT-10) high voltage current-limiting
fuse. It can reliably turn on any current up to the short-circuit
current, the load switch turns on the working current, the fuse
turns on the short-circuit current, and the fuse turns on any
overcurrent between the working current and the full short-circuit
current. At the same time, the fuse switches off the load switch
through its impinger. TECHNICAL PARAMETER The technical
