Abstract

Es wird ein Schaltwerk für ein elektrisches Schaltgerät, insbesondere für einen Leitungsschutzschalter beschrieben, der einen Schaltknebel (12) aufweist, der über ein Schaltschloß ein bewegliches Kontaktstück (22) in Einschaltstellung bringt, wobei bei der Einschaltbewegung eine Totpunktlage des Schaltschlosses überquert wird. Das Schaltwerk besitzt eine erste Verklinkungsstelle, die das Schaltschloß in der Einschaltstellung hält, und die von einem thermischen Auslöser geöffnet wird. Zur Erzielung einer bestimmten Einschaltgeschwindigkeit zumindest im letzten Abschnitt der Einschaltbewegung ist eine zweite Verklinkungsstelle (27, 28) vorgesehen, die eine ortsfeste Anlagestelle (28) für einen mit dem beweglichen Kontaktstück (22) gekuppelten Bügel (26) aufweist. Mit dem Schaltknebel (12) ein als Schieber ausgebildetes Auslöseelement (38) gekuppelt, daß die zweite Verklinkungsstelle (28, 27) entriegelt, so daß sich das bewegliche Kontaktstück (22) beschleunigt in Einschaltstellung bewegen kann.

Figure 00000001
A switching mechanism for an electrical switching device, in particular for a circuit breaker, is described which has a switching toggle (12) which brings a movable contact piece (22) into the switch-on position via a switch lock, a dead center position of the switch lock being crossed during the switch-on movement. The switching mechanism has a first latching point, which holds the switch lock in the switch-on position and which is opened by a thermal release. To achieve a certain switch-on speed, at least in the last section of the switch-on movement, a second latching point (27, 28) is provided, which has a fixed contact point (28) for a bracket (26) coupled to the movable contact piece (22). A trigger element (38) designed as a slide is coupled to the switching knob (12), which unlocks the second latching point (28, 27) so that the movable contact piece (22) can accelerate into the switched-on position.
