through the conductor or with standing capacity of the
breaker.the KA is decided mostly that incoming transformer
fault current
Is This Answer Correct ? | 1 Yes | 0 No |
The value of the kA rating determines how much current the circuit breaker can withstand under fault conditions. The circuit breaker only has to withstand this for a brief period of time, usually the time it takes for the circuit breaker to trip. For example, a value of 6kA means that the circuit breaker can withstand 6,000 amps of current during the brief time it takes to trip.
