Product Details

VOG-12/MS series vacuum permanent magnetic circuit breaker

VOG-12/MS series vacuum permanent magnetic circuit breaker mainly composed by solid seal post, current transformers, permanent magnetic actuator and the cabinet composition. This type circuit breaker is small design, high quality stainless steel cabinet housing. At the same time with a manual emergency brake device (can be configured according to user needs to install manually switch device , the parameter of manual closing reached to the same value of electrical closing, to meet with a load of closing function). Isolation switch and current transformers can be selected according to user needs.
