ZW32 Vacuum Circuit Breakers

ZW32-12/T630-20 Type Vacuum Circuit Breaker is outdoor distribution equipment with rated voltage12KV,rated current 630A,three-phase AC 50HZ.It is mainly used to open and close the load current,overload current and short-circuit current in the power system. It is suitable for frequent operation in agricultural power grid,power grid and industrial and mining enterprises. ZW32-12(D)/T630-20 combination switch is a 12KV outdoor high-voltage switchgear composed of vacuum circuit breaker and isolation switch and it’s linkage mechanism. In addition to all functions of the circuit breaker,it can also meet the requirement that there should be obvious isolation break when the circuit breaker is overhauled,and the isolation knife has a reliable mechanical interlocking device with the body of the circuit breaker,which can ensure the personal safety of maintenance personnel.According to the operating mechanism, the vacuum circuit breaker is divided into two types: spring operating mechanism and permanent magnet operating mechanism. Among them, the permanent magnet operating mechanism is divided into two types: bi-stable and mono-stable.ZW32 vacuum circuit breaker can be equipped with CT over-current protection, isolating switch, outdoor PT, intelligent controller (watchdog), metering box device, etc. according to user requirements, to meet the needs of various occasions.
