ZW8Q-12 series outdoor dual power automatic conversion vacuum circuit breaker groupDetailed product description：

The ZW8Q-12 series outdoor dual power automatic conversion vacuum circuit breaker group mainly consists of two ZW8 outdoor vacuum circuit breakers and a dual power automatic conversion controller. It is suitable for dual power supply systems with AC 50Hz, rated voltage 12kV and below, mainly powered by the main power supply. When the main power fails, it automatically switches to the backup power supply, and when the main power comes in, it automatically switches to the main power supply. This set of equipment is mainly used in important situations where power outages are allowed.
