Summary:2.1. In such circuit breakers, it is necessary to transmit the movement of a trip device by means of an intermediate element onto a locking point of the circuit breaker mechanism. In this arrangement, an adjustment capability must be provided in the transmission path for matching the trip device functions. The invention provides an adjusting device which is of simple construction and is non-interacting. 2.2. For this purpose, a trip lever (3), which can be rotated by a trip device (4), is arranged eccentrically such that it can pivot on an adjustable bearing body (2). By adjustment of the toothed bearing body (2), which is preferably arranged on the circumference side, by means of an adjusting tool (7), the trip lever (3), which acts on a latching pin (5) of the switch mechanism, can be set to predetermined nominal value functions. 2.3. The arrangement is especially suitable as an adjusting device for the thermal trip device of a power circuit breaker.
