Product Introduction
ZW20(ZW32-12 ) Series Outdoor High Voltage Vacuum Circuit Breaker is widely used in the power system of three-phase, which has AC 50Hz and 10~12Kv voltage level. The main function of the equipment is breaking and closing the loading current, and also it can protect electric consumption by tele-control and tell monitor. Meanwhile, ZW32-12 can be used in both Businesses biased and household-biased
