11KV Auto Recloser Vacuum Circuit Breaker
ZW32 series 11 kv outdoor vacuum circuit breaker are used in distribution systems and pole mounted recloser. 11 kv outdoor vacuum circuit breakers are used to make and break normal and fault currents. 11kv outdoor circuit 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 11 kv breaker by our electric power equipment ltd China is based on current standards IEC 62271-100. We can give you the most competitive 11kv vacuum circuit breaker price.

11 KV Outdoor Vacuum Circuit Breaker Application
The 11 kv outdoor vcb is equipped with one integrated current transformer per pole. The current transformer has a ratio of 600 A:5A.

VCB rating for 11kv Recloser is for protection purposes and optimized for operation with the controller. For more pole top switches at bulk price.
