    1. Temperature derating
The maximum permissible current in a circuit breaker depends on the ambient temperature where the circuit breaker is
placed. Ambient temperature is the temperature inside the enclosure or switchboard in which the circuit breakers are installed.

The reference temperature is 30ºC

When several simultaneously operating circuit breakers are mounted side by side in a small enclosure, the temperature rise inside the enclosure causes a reduction in current rating.

You must then assign the rating (already derated if necessary according to ambient temperatuer) a downrating factor of 0.8.
