11KV Auto Recloser Vacuum Circuit Breaker
ZW32 series 11 kv breakerare used in distribution systems. 11kv auto reclosers are used to make and break normal and fault currents. 11kv outdoor circuit breakerare fully equipped with sensors and a controller to provide a means of protection and control. In case of a line fault, breakers can break and make currents several times, thus avoiding longer network interruptions due to temporary faults.
The manufacture, design, and testing of the vcb 11kvbreaker by our electric power equipment ltd China is based on current standards IEC 62271-100. We can give you the most competitive11kv vacuum circuit breaker price.
11KV Auto Recloser Application
The 11 KV vacuum circuit breaker is equipped with one integrated current transformer per pole. The current transformer has a ratio of 600 A:5A.
VCB rating for 11kvRecloser is for protection purposes and optimized for operation with the controller.
