ZW32-12M type outdoor high voltage permanent magnetic vacuum circuit breaker

SUMMARY

ZW32-12M type outdoor high voltage permanent magnetic vacuum circuit breaker (hereinafter referred to as circuit breaker) for rated voltage 12kV, three-phase AC 50Hz outdoor power distribution equipment. The load current, overload current and short circuit current are mainly used in the open and close power system. Used for protection and control of substation and industrial and mining enterprises as well as frequent operation of rural power grid.This circuit breaker has the characteristics of small volume, light weight, anti condensation, free maintenance, and can adapt to the severe weather conditions and environmental pollution.This product adopts the permanent magnet operation mechanism of operation; the permanent magnet operating mechanism provided by the permanent magnet holding force, holding the switches in the opening and closing position, the small number of mechanical parts and mechanical transmission chain is short, thereby switching reliability and mechanical life is enhanced greatly.
