Sulfur hexafluoride circuit breaker - Wikipedia

The reduction of operating energy was mainly achieved by lowering energy used for gas compression and by making increased use of arc energy to produce the pressure necessary to quench the arc and obtain current interruption. Low current interruption, up to about 30% of rated short-circuit current, is obtained by a puffer blast.Get price
