Outdoor Customized 10KV 33KV ZW20-12-630A High-voltage Vacuum Circuit Breaker

ZW20-12 vacuum circuit breaker

Equipped with vacuum circuit breaker, the vacuum circuit breaker ensures stable breaking capacity and no dangerous explosion risk. The device is safe, maintenance-free, compact, light weight and has a long service life required for mechanical operation. The circuit breaker is encapsulated in an alcohol cover filled with SF6 or N2, with anti-condensation and moisture protection for high temperature and high humidity applications. The circuit breaker is equipped with a three-phase CT and outputs three-phase currents for analysis by an intelligent controller. The operation of the circuit breaker can be electric, manual or remote controlled. The operating mechanism can be freely replaced without affecting the looseness of the Lingshield. The service life is up to 10000 times. This product can be used with the controller as recloser, sectionalizer, load switch and coupling switch.
