Temperature Derating
The maximum permissible current in a supplementary protector depends on the ambient temperature and spacing be-
tween devices (see next paragraph). Ambient temperature is the temperature inside the enclosure or switch-board in
which circuit breaker is installed. The reference temperature for nominal current rating is 30°C.
