Magnetic tripping currents are increased by 20% on DC supplies. The time/current characteristic curve depends on the ambient temperature Accessories prevailing. In order to eliminate nuisance tripping, please multiply the circuit breaker current ratings by the derating factor shown below. See also section 9 – Technical information.
