FN5-12 Series Indoor AC high voltage load switch
Product Overview FN5-12 Series indoor High-voltage alternating current switch load applied to the exchange of 50Hz, 10kV network as breaking and closing load current by short-circuit current. With fuse switch and cut off the load short-circuit current for protection switching purposes. The CS Series switches equipped with a dedicated port or manual CS6-1-type manual operation agencies.
Features a, small size, light weight, simple structure, easy maintenance, operation of small force; b, a reliable mechanical interlock to prevent misoperation; C, clear visibility of the fracture; d, gas interrupter self-productive, stable performance, safe and reliable; E, there is lack of combination of electrical protection.
