The time/current characteristic curve depends on the ambient temperature
prevailing. In order to eliminate nuisance tripping, please multiply the circuit
breaker current ratings by the derating factor shown below. See also section

Multipole types: all poles symmetrically loaded.
With single pole overload, thermal tripping will be at
approx. 1.54 x I
N
with 2-pole devices and at
approx. 1.68 x I
N
with 3-pole devices.
