Product Description
* Load isolating switches are widely applied to distribution system and automation system in building, power, petrochemical and other industries.
* The acceleration mechanism with instantaneous release of spring storage achieves fast connection or separation, which has nothing to do with the speed of operation handle, and greatly improves the ability of extinguishing arc.
* The shell made of glass fiber reinforced unsaturated polyester resin has good flame retardancy, dielectric properties, carbonization resistance and impact resistance.
* The parallel double breakpoint contact has self cleaning effect.
* All contact materials are copper plated silver alloy with two separate contact surfaces.
* The distance is large.
* In the "O" position, you can use three locks to lock the handle at the same time, and reliably avoid misoperation.
* The switch is beautiful, novel and concise, with small volume and complete function.
