Product Description

Vacuum circuit breaker

 ZW32-40.5  Outdoor high voltage vacuum circuit breaker

       ZW32-40.5 outdoor high voltage vacuum circuit breaker adopts a unique design of integrated fixed pole and high reliability of the operating mechanism. The device is mainly used in the medium voltage overhead line power grid to close and open load current, overload current and short circuit current.    

√Extremely high reliability
√Complete maintenance free throughout life
√High mechanical and electrical life
√Small size, light weight, easy to install

     

      ZW32-40.5 outdoor high voltage vacuum circuit breaker is mainly composed of integrated fixed pole, current transformer, operating mechanism and box body. The circuit breaker is designed for miniaturization with high quality steel casing. Current transformer can be selected according to user'sneeds. ZW32-40.5 outdoor high voltage vacuum circuit breaker matches with intelligent control combination. The switch can be operated locally or remotely through the communication interface. Other information of circuit breaker can also be transmitted to the control center, communicationchannels can choose cable, optical fiber, GPRS/CDMA, GSM and so on.
