CIRCUIT BREAKER RATING
The circuit breaker must be capable of carrying continuously the full load current, without excessive temperature rise, and should be capable of interrupting fault currents safely.
An ac circuit breaker has the following ratings:
1. Rated voltage, rated current
2. Rated frequency
3. Rated breaking capacities
4. Rated making capacities
