ZW10-12M series of high-voltage vacuum circuit breaker is a three-phase AC outdoor high voltage switchgear, mainly for 12kv, rated frequency 50Hz power distribution system, especially for outdoor overhead lines, divided load current, overload protection, short circuit current
protection. The circuit breaker can be equipped with disconnector, the circuit breaker is installed on the side of the circuit breaker body, through the angle steel chassis combine circuit breaker together, the drive shaft with the interlock between the device and circuit breaker which can prevent misoperation.
The circuit breaker can be equipped with a compound controller type intelligent circuit breaker. And PT, coincidence controller with current flow control, over current protection and short circuit speed three sections of composite protection and 1 to 3 times reclosing, small current grounding protection, limited remote control, and also in the rod under the wireless remote control and other Function, and the controller parameters can be continuously set. It is the ideal choice for rural power grid substation, station outside point switch and simple metering switch.Main technical parameters:
