What is an AIC Rating?

An AIC Rating, or Ampere Interrupting Capacity Rating, is the maximum current that a circuit protection device such as a breaker or fuse can safely interrupt without damage. It is a critical specification for ensuring that electrical systems are adequately protected against short-circuit conditions. The AIC Rating must be equal to or greater than the fault current that can occur in the system.

Example Calculation

Example 1:

Step 1: Calculate the AIC Rating:

\[ AIC = 10 \text{ kA} \]

Example 2:

Step 1: Calculate the AIC Rating:

\[ AIC = 15 \text{ kA} \]
