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.
+140 °F
1) Magnetic tripping currents are increased by 20 % on DC supplies.
2) Magnetic tripping currents are decreased by 20 % on AC supplies.
