11KV Vacuum Circuit Breaker
ZW32 series Breakers are used in distribution systems. Circuit breakers are used to make and break normal and fault currents. 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 vacuum recloser is based on current standards IEC 62271-100.
Application of 11KV OutdoorCircuit Breaker
The vacuum circuit breaker is equipped with one integrated current transformer per pole. The current transformer has a ratio of 600 A:5 A. It is for protection purposes and optimized for operation with the controller.
