11KV Vacuum Circuit Breaker

11KV Vacuum Circuit Breaker

ZW32 series 11kv breakerare used in distribution systems. 11kv auto reclosers are used to make and break normal and fault currents. 11kv outdoor vcbcircuit breakers are 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 ltdChina is based on current standards IEC 62271-100. We can give you the most competitive11kv circuit breaker price.

Application of 11KV Vacuum Circuit Breaker

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 11kvis for protection purposes and optimized for operation with the controller.
