Short circuit current rating example
SpletThe short circuit rating is the maximum electrical current the device can tolerate before it fails. Consider, for example, a 100 amp circuit breaker. At some value of current exceeding 100 amps, you would expect the breaker to trip. If 150 amps passes through the breaker for a certain period of time, it should trip.
