Rupturing capacity of a circuit breaker? - Answer

Hence short circuit breaking capacity or short circuit breaking current of circuit breaker is defined as maximum current can flow through the breaker from time of occurring short circuit to the time of clearing the short circuit without any permanent damage in the CB. The value of short circuit breaking current is expressed in RMS The breaking capacity is the maximum current that can safely be interrupted by the fuse. This should be higher than the prospective short-circuit current. Miniature fuses may have an interrupting rating only 10 times their rated current The maximum value of current that a breaker can interrupt without facing any damage is called interrupting or rupturing capacity of the circuit breaker. They are also rated in MVA.
