Abstract

Es wird ein Installationsschaltgerät, insbesondere ein Leitungsschutzschalter beschrieben, der eine Polkontaktstelle (16) mit einem beweglichen Kontaktstück (20) und einem festen Kontaktstück (19), einen drehbar gelagerten, das bewegliche Kontaktstück (20) tragenden Kontakthebel (21) aufweist. Der Kontakthebel (21) wird einem Schaltschloß (12) mit Verklinkungsstelle angetrieben. Das Installationsschaltgerät besitzt eine thermischen Auslöser (14) und einen elektromagnetischen Auslöser, die beide auf die Verklinkungsstelle einwirken und von denen der elektromagnetische Auslöser direkt auf den Kontakthebel (21) einwirkt. Das Installationsschaltgerät besitzt weiterhin eine Neutralleiterkontaktstelle (23), die mit der Polkontaktstelle (16) derart gekoppelt ist, daß die Polkontaktstelle (16) früher öffnet bzw. später schließt als die Neutralleiterkontaktstelle (23). Das bewegliche Kontaktstück (24) der Neutralleiterkontaktstelle (23) ist an einem Arm (25) angebracht, der an einem vom Kontakthebel (21) der Polkontaktstelle (16) angetriebenen, federnd in Schließrichtung der Neutralleiterkontkatstelle (23) beaufschlagten Schieber (27) aus isolierendem Material festgelegt ist, dessen Schieberachse quer zu und durch das bewegliche Kontaktstück (20) der Polkontaktstelle (16) verläuft.

Figure 00000001
An installation switching device, in particular a circuit breaker, is described, which has a pole contact point (16) with a movable contact piece (20) and a fixed contact piece (19), a rotatably mounted contact lever (21) carrying the movable contact piece (20). The contact lever (21) is driven by a switching lock (12) with a latching point. The installation switching device has a thermal release (14) and an electromagnetic release, both of which act on the latching point and of which the electromagnetic release acts directly on the contact lever (21). The installation switching device also has a neutral contact point (23), which is coupled to the pole contact point (16) such that the pole contact point (16) opens or closes earlier than the neutral contact point (23). The movable contact piece (24) of the neutral conductor contact point (23) is attached to an arm (25) which is made of an insulating slide (27) on a slide (27) driven by the contact lever (21) of the pole contact point (16) and acted upon resiliently in the closing direction of the neutral conductor contact point (23) Material is defined, the slide axis of which runs transversely to and through the movable contact piece (20) of the pole contact point (16).
