Circuit-breaker

Temperature derating carrying capacity at the reference temperature:
Under certain installation conditions, the circuit- therefore the derating coefficients shown in the
breakers can operate at higher temperatures than table must be applied. Percentage values refer to
the reference temperature of 40 °C. In this case withdrawable and fixed circuit breaker.
the current-carrying capacity of the circuit- If not specified, all data refer to a copper accord-
breaker may be lower than the rated current- ing to IEC60947.
