	Overview:
ZW32-24 outdoor vacuum circuit breaker (hereinafter referred to as circuit breaker) is an outdoor Power distribution equipment with a rated voltage of 24kV and three-phase AC 50Hz. It is mainly used to break and close the load current, overload current and short-circuit current in the power system. It is suitable for protection and control in substations and industrial and mining enterprises' power distribution systems, as well as places where rural power grids are frequently operated.
This circuit breaker has the characteristics of small size, light weight, anti-condensation, and maintenance-free, and can adapt to severe climatic conditions and dirty environments.
