Product Description

Product Description

FKN12 and FKRN12 combination appliances are three-phase high-voltage switchgear with rated voltage 12KV and rated frequency 50Hz, used for switching load current, closed loop current, no-load transformer and cable charging current, closing short-circuit current, fuse combination appliance It can break short-circuit current, and the load switch equipped with grounding switch can withstand short-circuit current. It is mainly used in urban distribution stations and industrial electrical equipment for three-phase ring network or terminal power supply, for load control and short-circuit protection.
