Temperature derating
The maximum permissible crrent in a circuit breaker depends on the
ambient temperature where the circuit breaker is placed. Ambient
termperature is the temperature in side the enclosure or
switchboard in which the circuit breakers are installed.
The reference temperature is 30℃
