Circuit breaker, and cabeu00c7ote of imu00e7 for a circuit breaker. In a circuit breaker with an overcurrent trip device combined / short circuit current must have a well - defined in the case of an over current and in the event of a short circuit current. For this purpose, they need to be established with precision intervals (a, b).If the housing is made of a material of accommodation in cost effective as thermoplastics irreversible, he is liable to have shrunk - chin. As a result, the intervals mentioned may change. According to the invention, firstly an armature (24) is mounted in such a way that it changes its rotational position of rest in the event of shrinkage of the housing.A head of magnet (28) as part of the overcurrent trip device. Short circuit current, is mounted and shaped in such a way that the rotation is compensated accurately, so that the mensionados intervals do not change despite the shrinkage.
