High reliable ZW32M-12 permanent magnetic outdoor high voltage vacuum circuit breaker

ZW32M-12 outdoor three-poles high voltage permanent magnetic mechanism are mainly opening and closing loading current, overload current and circuit breaking current in power system. They are appropriate in protecting and controlling power system in mining industrial enterprise, also in rural grid and frequent operation places. This kind of product not only conserved all the reasonable part and excellent characteristics of type ZW32, but also make the largely enhanced mechanical life of the whole device including vacuum interrupter, reaching 50000 times. Free of maintenance within 20000 times during operation.
