Electromagnetic tripping mechanism and the protective switching device

摘要

According to the invention, the electromagnetic tripping mechanism (1) for a protective switching device, in particular for a fault current circuit breaker or a differential current circuit breakers, has a magnet system (10), a release element (4) which, in a bearing point (6) relative to the magnet system (10) between a first position and a second position is rotatably mounted, as well as a spring element (15), whose first end with the magnet system (10) is mechanically coupled, and whose second end to the trip element (4) is mechanically coupled, on. Furthermore, the triggering device (1) is a deflecting element (8), which is arranged in such a way that the spring element (15) in the case of a movement of the second position to the first position by means of in such a way, the deflecting element (6) is guided, that a force (f_R) results here, which essentially in the direction of the bearing point (6) is oriented. During the return of the triggering device (1) ready in the release position, the spring element (15) via the deflecting element (8) and thereby guided diffracted. The deflecting element (8) in this case exerts a force on the spring body of the spring element (15) from. Correspondingly, also a force (f_R) of the spring element (15) on the deflecting element (8), which according to the invention essentially in the direction of the bearing point (6) is oriented. This has the consequence that the release element (1) in the bearing point (6) and is forced is reliably guided.
