Note: For feed-thru cabinets only (-FT), the model name is complete after step two. Skip steps three and four.
What is AIC?
When a short circuit occurs, a large amount of current flows into the circuit breaker
and it trips. The Ampere Interrupt Capacity rating is the maximum current the breaker
can safely interrupt. If the short circuit current exceeds the AIC rating of the breaker,
the circuit breaker may fail. For safe operation, the AIC rating must exceed the
available fault current at the panel.
