8DA10-8DB10 | Medium-voltage switchgear - Siemens USA: Can the circuit breaker interrupt if there is a leak and no SF 6 gas is available? A: Yes, the vacuum interrupters are independent of the SF 6 gas and all the interruption occurs inside the vacuum interrupters. SF 6 gas is only used for insulation.. Q: What is the probability of SF 6 leakage? A: The low leakage rate is possible as the normal pressure is 1.5 bar (22 psig) or less, as the SF ...
