Abstract

Es wird ein elektrisches Installationsgerät, insbesondere Leitungsschutzschalter oder Motorschutzschalter vorgeschlagen, mit einem Gehäuse mit Anschlussräumen und Anschlussmitteln (2, 3) zur Verbindung mit Stromschienen und/oder Anschlussleitungen an beiden Stirnseiten und mit mindestens einem Schaltkontakt mit einem feststehenden und einem beweglichen Kontaktstück (4, 6), zwischen denen bei einer Ausschaltung ein Lichtbogen (13) in einem Lichtbogen-Vorkammerraum (7) entsteht. Der Lichtbogen läuft über Lichtbogenleitschienen (12, 16) in eine strombegrenzende Lichtbogenlöscheinrichtung (12), insbesondere Lichtbogenlöschblechpaket ein, wobei randseitig der Lichtbogenlöscheinrichtung (12) wenigstens eine Isolierplatte (20, 25 + 26) angeordnet ist. Die Isolierplatte (20, 25 + 26) ist mittels eines Befestigungsbügels (22) am Endabschnitt einer Lichtbogenleitschiene (14) befestigt.

Figure imgaf001
It is proposed an electrical installation device, in particular circuit breaker or motor protection switch, with a housing with connection spaces and connection means (2, 3) for connection to busbars and / or connection lines on both end sides and at least one switching contact with a fixed and a movable contact piece (4, 6), between which an arc (13) in an arc prechamber space (7) is formed during an elimination. The arc passes through arc guide rails (12, 16) in a current-limiting arc quenching device (12), in particular arc splitter stack, at the edge of the arc quenching device (12) at least one insulating plate (20, 25 + 26) is arranged. The insulating plate (20, 25 + 26) is fixed by means of a mounting bracket (22) at the end portion of an arc guide rail (14).
