The KA rating is a measure of the circuit breaker's ability to handle excessive current safely. It represents the maximum fault current that a circuit breaker can interrupt without causing damage to the breaker itself or the electrical system. The KA rating is typically expressed in kiloamperes or thousands of amperes (kA).what is the ka rating on a circuit breaker | DvoltWas this helpful?
