ABSTRACT:
An adjusting device is for a thermal trip of a switchgear. It includes a bimetal, which is held in a fixed manner on a bimetal support, whose free end is located at a distance from a tripping lever, and which increasingly acts upon this tripping lever in a tripping direction as a result of thermal deformation. A distance can be adjusted by deforming the bimetal support. The adjusting device is particularly suited for use in circuit-breakers or the like.
