An improvement to prevent alteration of the circuit breaker calibration due to high overloads. A circuit breaker has a U-shaped current path with a brazed junction at the bend of the "U". Upon the occurrence of a large overload, the opposing current in the two legs of the U-shaped path will force the two legs of the "U" apart, possibly weakening the brazed junction. When one of the legs is a closely calibrated component of a trip assembly, the breaker will no longer operate within the proper range. A stop is placed within the housing to prevent the two legs from moving apart such a distance as will cause the brazed junction to fail.
