Abstract

Die Erfindung betrifft eine Kontaktanordnung für strombegrenzende Schutzschalter im Niederspannungsbereich mit festgehaltener elektrodynamischer Kontaktöffnung. Sich um einen Lagerbolzen (14) windende Kontaktdruck-Drehfedern (30; 32) stützen sich jeweils zwischen einem federkraftbeaufschlagten Rastnocken (44; 46) und einem Arm einer Drehkontaktbrücke (16) ab. Durch entsprechende kopfseitige Formgebung des Rastnockens (44; 46) wird beim Auftreten eines Kurzschlussstromes der auf die Drehkontaktbrücke (16) wirkenden elektrodynamischen Öffnungskraft ein veränderliches Drehmoment entgegengesetzt. Dieses durch die Kombination aus Drehfedern (30; 32) und federbeaufschlagten Rastnocken (44; 46) erzeugte Drehmoment bewirkt zum einen eine anfängliche Verzögerung der Abstoßbewegung und zum anderen den Übergang der Drehkontaktbrücke (16) in eine rastende Abstoßstellung.
