Vacuum Circuit Breaker - Indoor

Description: Ubivac indoor vacuum circuit breaker, 800-2000 A, indoor switchgear 12 kV. is designed and tested to conform IS 131 181 IEC 60056 and 66221-100. Vacuum interrupters are used. Low-energy spring mechanism is also used. It has porcelain clad vacuum interrupters or (polycrete cast vacuum interrupters) similar to conventional outdoor high-voltage switchgear and is suitable for outdoor substation ensuring safety from fire hazard. It has common duct to mount three poles of breaker and to house common horizontal operating shaft. Base cabinet is designed to house the spring operating mechanism which is mechanically linked to all three poles. Circuit breaker has high reliability due to vacuum interruption. It offers long electrical and mechanical life and negligible maintenance (maintenance conforms to cleaning and lubricating of operating mechanism).
