摘要:
In line circuit breakers with a combined overcurrent/short-circuit current tripping device, tripping should take place in a well defined manner in the case of an overcurrent and in the case of a short-circuit current. For this purpose, gaps (A, B) need to be set precisely. If the housing is made from a cost-effective housing material such as thermosetting plastic it is subject to shrinkage. As a result, the mentioned gaps may change. An armature (24) is mounted in such a way that it changes its rest rotary position in the event of shrinkage of the housing. A magnet yoke (28) as part of the overcurrent/short-circuit current tripping device is mounted and shaped in such a way that the rotation is compensated for precisely, so that the mentioned gaps do not change despite the shrinkage.

摘要:
An adjusting device is for a thermal trip element of a switchgear. It includes a bimetallic element that is stationarily fixed on a bimetallic support. The free end of the bimetallic element is spaced apart form a trip lever and increasingly impinges the same in the direction of release was a result of the thermal deformation, the distance being adjustable by bending the bimetallic support. The adjusting device is especially suitable for circuit breakers or the like.
