Abstract

Eine Kontaktanordnung für einen Leistungsschalter weist be­ wegbare und feststehende Hauptkontakte (20, 28) sowie bewegbare und feststehende Hauptkontakte (20, 28) sowie bewegbare und feststehende Vorkontakte (24, 30) auf. Zur beschleunigten Über­ führung an den Hauptkontakten (20, 28) entstehender Schalt­ lichtbögen zu den Vorkontakten (24, 30) weist der die beweg­ baren Kontakte tragende Kontakthebel (18) an seiner kontakt­ gebenden Unterseite eine Vertiefung (32) und im Abstand hiervon an der gegenüberliegenden Oberseite ebenfalls eine Vertiefung (34) auf. Die Vertiefungen (32, 34) bewirken einen Verlauf des Strompfades (36) innerhalb des Kontakthebels (18) in Form einer Schleife derart, daß an den Hauptkontakten (20, 28) entstehende Schaltlichtbögen elektrodynamisch in Richtung der Vorkontakte (24, 30) verschoben werden. Die beschriebene Kontaktanordnung eignet sich beispielsweise für Niederspannungs-Leistungs­ schalter in kompakter Bauart mit Isolierstoffgehäuse.
