Abstract
A compact equipment protecting electrical circuit breaker having a short-circuit and excess current tripping action as well as a signal change switch for actuating and protecting household appliances, office machines, manufacturing devices and the like, includes a breaker and tripping mechanism which is a combination of a cocking body (5) with an unlatching lever (4) supported therein, a tilting contact piece (6), and a cam lever (14) with the functional inclusion of several spring elements. The combination is mounted on a common axis in a central location below the operating mechanism (1-3) and between the hinged armature system (8) and a bimetal strip (10). The combination is further located or mounted above an arc quenching chamber (12) and above a signal change switch contact device (13) and above the various breaker terminals (15). The change switch has its own terminals for signalling the instantaneous operating condition of the circuit breaker.
