ZW14A-12 Outdoor high-voltage vacuum circuit breakerDetailed product description：

ZW14A-12 outdoor high-voltage vacuum circuit breaker is an outdoor high-voltage switchgear with a rated voltage of 12kV and three-phase AC 50Hz.

The operating mechanism dedicated to the integration of ZW14A-12 outdoor high-voltage vacuum circuit breaker mechanism and switch is spring energy storage, which can be operated by AC/DC energy storage or manually operated.
This circuit breaker has a simple structure, strong breaking capacity, long service life, complete operating functions, no explosion hazard, and easy maintenance. It is mainly suitable for 12kV systems in rural and urban power grids, and is used for dividing and combining load currents, overload currents, and short-circuit currents. It can also be used in other similar places.
