LW3F type pole-install load switch was used in 12kV,24kV,33kV rated voltage, rated current 400/630A; 50/60HZ with the load current; over load current of power line open circuit and opening and closing electric systems.The switch can equiped with a conttoller with most advanced technical parameter.
LW3F-A type LW3F is manaully LBS for choice.
LW3F-M type LW3F is a intelligent type LBS for choice. It can automatically disconnect when the distribution line was break down. It could operated by handle; Implementt electro motion and distant. The electric controller was installed in stainless steel cabinet. So it could use in any conditions.
