Circuit breakers
High temperatures
b A rise in temperature causes lowering of the thermal threshold
(tripping on overload).
b Protection is still ensured: the tripping threshold remains lower than the current
acceptable by the cable (Iz)
b To prevent nuisance tripping, it should be checked that this threshold remains
higher than the maximum operating current (IBRIWKHFLUFXLWGH¿QHGE\
v the rated load currents,

the operating current IB, switchboard ventilation should be provided for.
Low temperatures
b A fall in temperature increases the thermal tripping threshold of the circuit breaker.
b There is no risk of nuisance tripping: the threshold remains higher than the
maximum operating current of the circuit (IB) demanded by the loads.
b It should be checked that the cable remains suitably protected, i.e. that its
acceptable current (Iz) is higher than the values shown in the following tables
(in amperes).
When the ambient temperature could vary within a broad range, both these aspects
must be taken into account:
b the difference between the maximum operating current of the circuit (IB) and the
tripping threshold of the circuit breaker for the minimum ambient temperature,
b the difference between the strength of the cable (IZ) and the maximum tripping
threshold of the circuit breaker for the maximum ambient temperature.

temperature in which it is placed.
b The ambient temperature is the temperature inside the enclosure or switchboard
in which the devices are installed.
b The reference temperature is in a halftone colour for the different devices.
b When several devices operating simultaneously are mounted side by side in a
small enclosure, a temperature rise in the enclosure results in a reduction in the
RSHUDWLQJFXUUHQW$UHGXFWLRQFRHI¿FLHQWRIZLOOWKHQKDYHWREHDVVLJQHGWRWKH
rating (already derated, if applicable, depending on the ambient temperature).
b Example:
Depending on the ambient temperature and the method of installation, the table
below shows how to determine, for an iC60, the operating currents not to be
exceeded for ratings 25 A, 32 A and 40 A (reference temperature 50°C).
