Product Description

ZW32M-12/630-25 12kV Permanent Magnet and

Spring Outdoor Vacuum Circuit Breaker

Product Description

 

Product detail
ZW32M-12 / 630-25 permanent magnet outdoor vacuum circuit breaker (hereinafter referred to as circuit breaker) is an outdoor power distribution equipment with rated voltage of 12kV and three-phase AC 50Hz. It is mainly used for breaking and closing load current, overload current and short-circuit current in power system. It is suitable for protection and control in substation and distribution system of industrial and mining enterprises, and places where rural power grid operates frequently.
Using conditions
Ambient air temperature: -30°C ~+60°C;
Altitude:≤ 3000 meters;
The wind speed:≤ 34m/s;
Vibration or ground movement from the outside of the switchgear cell system can be ignored;
Pollution level: Level IV;
Storage temperature -40°C ~+85°C.
