Abstract

Die Erfindung bezieht sich auf ein für einen an drei Phasen anzuschließenden Verbraucher geeignetes Schalt­ gerät, insbesondere ein Schütz.
Bei einem derartigen Schaltgerät ist von den drei Strombahnen mit Festkontaktteilpaaren (4, 5, 6) und Kon­ taktbrücken (11, 12, 13) eine derart gegenüber den anderen zwei beim Einschalten vor- und beim Ausschalten nach­ eilend angeordnet, daß sowohl das vorschriftsmäßig gefor­ derte Schaltvermögen als auch die erforderliche Trennstel­ lenlänge erfüllt sind.
Hierdurch ergibt sich eine erhebliche Einsparung an Kontaktauflagevolumen (18) für die eine Kontaktstelle.
