Description
ZW32-24F series outdoor pole mounted high voltage vacuum circuit breaker is used as the main control and protective equipment in three phases power system of AC50Hz, voltage 24KV to switch on/off loading current overloading current and short circuit current, it applies to distribution system of substation, industrial enterprises to control and protect the downstream equipment.

The breaker adopts vertical column, dry structure, it has function of reliable insulation, long electric life and free maintenance. It is specially used for places where it needs frequent operation and rural network where has little maintenance services.
