Description
High Voltage Vacuum Circuit Breaker , Outdoor Pole-mounted Vacuum Breaker
General
ZW20A-12 Outdoor Pole-mounted Vacuum Circuit Breaker is a kind of outdoor distribution equipment, three-phase, AC50Hz, with rated voltage of 12kV. It is mainly used in power distribution network to break, open and close load current, overload current and short-circuit current. It is also used in substation, industrial and mining enterprises, urban and rural power grid for control and protection. And it is more suitable for frequency operation and the urban distribution automation network.
