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
Technical information.
Multi pole devices: all poles symmetrically loaded. With single pole overload,
thermal tripping will be at max. 1.7 x I
N
with curves F1, F2 and M1.
1)
Magnetic tripping currents are increased by 30 % on DC supplies
(curves F2, M1).
