Capacitor Bank Switching With Tavrida Vacuum Circuit Breakers
To summarize it, we would be happy if it would, but, unfortunately, capacitor rated current alone does not define vacuum circuit breaker applicability. It can be a huge 1000A rated bank, however damped with a proper series inductance, which would produce energization current only a little higher than the bank rated current, and the breaker would work fine.
