Applications of Cutout Switch ZW8-12/C

The ZW8-12/C outdoor HV vacuum breaker has all functions of the basic mode breaker. Matching with the reclosing controller, it becomes a recloser intelligence breaker. The basic mode breaker can match with a reclosing controller and PT reclosing controller, having three segment compound protection of switch on rush current control, over current protection and short quick break. And it has 1~3 times reclosing, low current ground protection, and wired supervisory control functions. It can also remote control under the pole, and regulate the parameters of the breaker.
