1. Product name: FK(R)N12-12 Load switch
2. Rated voltage(12kV)
3. Rated current(630,125A)

FK(R)N12-12 Load switch and combination apparatus is used for load control or short-circuit protection in indoor AC 50Hz, 12kV Looped net or distribution system or substation for terminal power supply. It is commonly installed in AC Metal-closed switchgear as master switch. The rated current breaking with load switch and the short-circuit breaing with fuse. Due to its favourable protective performance, combination apparatus is specially suitable for looped net power supply unit and prefabrication substation(or case).
