Abstract

Ein Schaltgerät (1), insbesondere ein Leistungsschaltgerät, weist zwei in Reihe geschaltete Schaltkontaktpaare (2, 3) zur Unterbrechung einer Strombahn (4) und zumindest ein im Bereich der Schaltkontaktpaare (2, 3) angeordnetes Löschpaket (5) zum Löschen der beim Öffnen der Strombahn (4) entstehenden Lichtbögen (6) auf. Die Schaltkontaktpaare (2, 3) sind derart angeordnet, dass ihre Öffnungsbahnen (7) im Wesentlichen parallel oder antiparallel zueinander verlaufen. Erfindungsgemäß sind die Schaltkontaktpaare (2, 3) derart in Reihe geschaltet, dass der in den beiden Lichtbögen (6) fließende selbe Strom (i) räumlich in die gleiche Richtung fließt. Das Löschpaket (5) ist im Bereich zwischen den Öffnungsbahnen (7) angeordnet.

A switching device (1), in particular a power switching device, has two series-connected switching contact pairs (2, 3) for interrupting a current path (4) and at least one in the region of the switching contact pairs (2, 3) arranged erase package (5) for deleting the opening the current path (4) resulting arcing (6). The switching contact pairs (2, 3) are arranged such that their opening tracks (7) are substantially parallel or antiparallel to each other. According to the invention, the switching contact pairs (2, 3) are connected in series in such a way that the same current (i) flowing in the two arcs (6) flows spatially in the same direction. The extinguishing package (5) is arranged in the region between the opening tracks (7).
