Adjustable short-circuit release

The invention relates to an overcurrent release with a yoke, with a coil winding, with a pole, with an armature and with a restraining spring for pre-stressing the armature, wherein an air gap exists between the pole and the armature. The invention is based on the object of specifying an overcurrent release with low force tolerances for the restraining spring, whose response value can be adjusted retrospectively and a circuit breaker with such an overcurrent release. This object is achieved in the case of an overcurrent release of the type mentioned at the outset by virtue of the fact that the restraining spring is in the form of a compression spring provided between the pole and the armature and that the overcurrent release is designed such that the compression spring is replaceable. Compression springs can be produced with lower force tolerances than torsion springs, as a result of which, also advantageously within the permissible tolerance in accordance with IEC60947 of +-20%, the response current can be reduced to, for example, 13 times the rated current minus 20%. Furthermore, compression springs do not have any friction between the turns and do not have as unfavourable friction as a torsion spring mounting arrangement. In addition, the replaceablity of the compression springs makes it possible to shift the response value of the overcurrent release on the finished overcurrent release or finished device retrospectively and easily.
