Dissipated powers
To ensure service continuity of the plants, how to keep the temperature within acceptable levels for
operation of the various devices and not only for the circuit-breakers must be carefully assessed,
for example with recourse to forced ventilation in the switchboards and in the rooms where they
are installed.
The table gives the dissipated power values per single pole at the rated current In for each circuit-
breaker used. The total maximum dissipated power for a circuit-breaker used at 50/60Hz is equal
to the power per single pole multiplied by the number of poles.
