Automatic Reclosing Switch

1.Scope of application

Outdoor high voltage vacuum circuit breaker (Automatic Reclosing Switch) is an outdoor distribution equipment with rated voltage of 12kV and three-phase alternating current of 50Hz.It is mainly used to open and close load current, overload current and short circuit current in power system.It is suitable for the protection and control in the power distribution system of substation and industrial and mining enterprises, as well as the places where the rural power grid is frequently operated. The circuit breaker has the characteristics of small volume, light weight, anti-condensation, free maintenance and so on. It can adapt to the harsh weather conditions and dirty environment.
