Abstract

Ein Hilfsstromauslöser für Leitungs-, Fehlerstrom- und Motorschutzschalter, insbesondere in Industrieanlagen, mit einer Auslösung durch ein elektrisches Signal oder eine Unterspannung besteht im Hinblick auf eine kompakte und preiswerte nachrüstbare Ausbildung aus einem Gehäuse, das seitlich an dem Schutzschaltergehäuse anbringbar ist, einer in dem Gehäuse vorgesehenen Anordnung aus Magnetspule 16, Schwenkhebelanker 17 und Ankerfeder 18, wobei die Magnetspule 16 über einen Hilfskontakt 31 mit Anschlußklemmen 13, 14 an der Gehäuseaußenseite verbunden ist, wobei der Schwenkhebelanker 17 einen Angriffsabschnitt 19 für die Ankerfeder 18, eine Nase für einen Unterspannungshilfskontakt und eine an einem Schwenkhebelende ausgebildeten Betätigungsabschnitt 34 für einen seitlich in das Schutzschaltergehäuse eingreifenden Zapfen 36 zur Betätigung des Schaltschlosses des Schutzschalters aufweist und aus einem mit dem Betätigungszapfen 36 in Eingriff befindlichen Mitnahmeschwenkhebel 29, der ein Betätigungsende 31 für den Arbeitsstromauslöser-Hilfskontakt 26 aufweist, wobei die Anordnung aus Magnetspule 16, Schwenkhebelanker 17 und Ankerfeder 18 in einer ersten Einbaustellung für Signalauslösung und in einer zweiten umgeklappten Einbaustellung für eine Unterspannungsauslösung vorgesehen ist.

Figure 00000001
An auxiliary current release for line, residual current and motor protection switch, especially in industrial plants, with a triggering by an electrical signal or an undervoltage is in view of a compact and inexpensive retrofit training of a housing which is laterally attachable to the circuit breaker housing, one in the Housing provided arrangement of magnetic coil 16, pivot lever armature 17 and armature spring 18, wherein the magnetic coil 16 is connected via an auxiliary contact 31 with terminals 13, 14 on the outside of the housing, wherein the pivot lever armature 17 an engaging portion 19 for the armature spring 18, a nose for an undervoltage auxiliary contact and a formed on a pivot lever end actuating portion 34 for a laterally engaging in the circuit breaker housing pin 36 for actuating the switching mechanism of the circuit breaker and from an engaging with the actuating pin 36 driving pan ebel 29, which has an actuating end 31 for the shunt release auxiliary contact 26, wherein the arrangement of magnetic coil 16, pivot lever armature 17 and armature spring 18 is provided in a first installation position for signal release and in a second folded-down position for an undervoltage release.
