Abstract (en)
[origin: EP0543208A1] The protective circuit breaker has a frame (9) which consists of insulating material and has an integrally formed bearing support (30) on which a switching rocker (33) is arranged such that it can pivot. Via coupling arms (39) and a cam lever (27), this switching rocker operates at least one contact spring (5) which forms a switching contact with a stationary contact element (1). A tripping mechanism having a bimetallic strip (13) and a switching latch (17) trips the lock of the cam lever (27) in the event of heating resulting from an overcurrent. <??>The switching rocker (33) is mounted, as are the other parts, without additional bearing pins or other mounting elements. A restoring spring (53) is seated on a curved projection (57) of the frame and engages in a fork projection (59) of the switching rocker (33). In this way, the switching rocker (33) and the restoring spring (53) are guided and aligned with respect to one another as well as possible, using parts which are as simple as possible. The switching rocker itself is mounted via sprung tongues (37) such that it can be latched on integrally formed bearing journals (31) of the frame (9). <IMAGE>
