DNH8(HGL)-125A~3150A/C side-operated load isolation switch is suitable for circuit connection and disconnection or electrical isolation. There are three poles, four poles (three poles + neutral pole can be connected), 1000A and above are only applicable For electrical isolation.
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.
Direct operation: the handle is installed on the switch
Operation outside the cabinet: the handle is installed outside the door of the power distribution cabinet
*The acceleration mechanism with spring energy storage and instantaneous release realizes quick connection or breaking (138 m/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.
