Suitable Conditions

Normal working conditions and installation conditions
*The ambient air temperature is not higher than +40℃, not lower than -5℃, and the relative humidity is not higher than 95%
*The altitude of the installation site does not exceed 2000 meters
*No explosive dangerous medium.
*Environment without rain and snow

Note: If the ambient air temperature is expected to be higher than +400℃ or lower than -50℃, the user should explain to the manufacturer.


Product Advantage

*The accelerating mechanism with spring energy storage and instantaneous release realizes quick switching on or off (138m/s), which greatly improves the arc extinguishing ability
*The shell made of glass fiber reinforced unsaturated polyester resin has good flame retardancy, dielectric properties, carbonization resistance and impact resistance
*Parallel double breakpoint contacts have self-cleaning effect
*All contacts have two separate contact surfaces. The isolation distance is large. When in the "O" position, three locks can be used to lock the handle at the same time to reliably avoid misoperation.
