The ZW10-12G/T630-12.5/16/20 type outdoor high-voltage vacuum circuit breaker is a three-phase AC outdoor high-voltage switchgear.
It is mainly used in 12kV-level distribution systems with a rated current of 630A and a frequency of 50Hz. It is particularly suitable for outdoor overhead lines, handling load currents, overload currents, and short-circuit currents, and for switching and protecting power grids in agricultural networks, urban networks, mines, railways, and ports.
According to customer requirements, the unit can be equipped with protective measurements, metering CTs, and single or double PTs, realizing the intelligence of the equipment.
