Ir on a breaker
WebThe AIC rating is the highest amount of current that the circuit breaker has been tested to interrupt before the circuit breaker fails or possibly explodes. Another common misconception is that the circuit breakers AIC rating means that whatever is supplied by the circuit breaker is protected up to the marked AIC rating. This is also incorrect.
