Product Description

2500A skt1 1250a/4p/n automatic power changeover switch    
Use range Distribution system and automation system in petrochemical industry,Construction ,power ,
 Case material Glass fiber reinforced unsaturated polyester
Operate mechanism Acceleration mechanism with spring energy storage and instantaneous release
Instantaneous on-off double break contact mechanism
Front operation,
Function Rated voltage 660v  DC Rated voltage 440v from 100-3150Amp,
Used for infrequent connection and disconnection of circuit and line isolation

Product characteristics
1. The acceleration mechanism of instantaneous release of spring energy storage realizes fast on or off (13.8 M / s), which is independent of the speed of the operating handle and greatly improves the ability of arc extinguishing.
2. The shell made of glass fiber reinforced unsaturated polyester resin has good flame retardant, dielectric, carbonation and impact resistance.
3. The parallel double break point contact has self-cleaning function.
4. All contact materials are copper silver alloy with two separate contact surfaces.
5. Large isolation distance.
6. When it is in "0" position, three locks can be used to lock the handle at the same time to avoid misoperation.
