Limit circuit fault

Larger circuit-breakers are 14 kA or higher. Current limiting circuit breakers may handle 200 kA. These ratings, for a particular design, vary with the rated voltage, decreasing as the applied voltage increases – a current limiting circuit breaker may have an interrupting rating of 200 kA at 240 V, 150 kA at 480 V, and 100 kA at 600 V.
