10kV 12kV Indoor LBS Disconnector AC High Voltage Electric Type Air Pneumatic Switch Load Break Switch

Model: FKN12-12D

Description

FKN12-12D/630-20 indoor AC high-voltage 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 cable charging current, off combined short-circuit current. The load switch equipped with the grounding switch can withstand short-circuit current.

FKN12-12D/630-20 indoor AC high-voltage 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 cable charging current, off combined short-circuit current. The load switch equipped with the grounding switch can withstand short-circuit current.

FKN12-12R.D/100-31.5 type indoor AC high voltage load switch-fuse combination is an indoor high voltage switchgear that combines FKN12-12D load switch and XRNT port-12 high voltage current limiting fuse. It can reliably break any current up to the short-circuit current: the load switch breaks the working current, the fuse breaks the short-circuit current, and jointly breaks any overcurrent between the working current and the full short-circuit current, and the fuse makes The load switch is open.
