Overview:
FN12-12D and FN12-12DR combination appliances are three-phase high-voltage switchgear with rated voltage of 12KV and rated frequency of 50Hz for splitting load current, closed-loop current, no-load transformer and cable charging current, closing short-circuit current, fuse combination The short-circuit current can be interrupted, and the load switch equipped with the grounding switch can withstand the short-circuit current. It is mainly used in the urban substation and industrial power equipment with three-phase ring network or terminal power supply. It is used for load control and short circuit protection.
