Abstract

Die Erfindung betrifft ein elektromagnetisches Auslösesystem (1) für einen Leitungsschutzschalter, mit einem Magnetsystem (2) mit Schlagstift (45), mit einem um eine gehäusefeste Achse (4) drehbar gelagerten Kontakthebel (5), mit einem um eine Schwenkachse (6) verschwenkbar gelagerten Steuerhebel (7), der eine erste Koppelstelle (8) hat, an der eine Fesselfeder (9) mit ihrem ersten Ende (10) angreift, wobei die Rückhaltekraft der Fesselfeder den Steuerhebel (7) in dessen Ruhelage hin beaufschlagt, und wobei der Steuerhebel (7) unter Einwirkung des Schlagstiftes (45) aus seiner Ruhelage entgegen der Rückhaltekraft der Fesselfeder (9) in seine Auslöselage verschwenkbar ist, wobei zwischen dem Kontakthebel (5) und dem Steuerhebel (7) eine Kopplung besteht, die eine Verschwenkbewegung des Steuerhebels (7) in eine Verschwenkbewegung des Kontakthebels (5) überträgt. Der Steuerhebel (7) besitzt eine zweite Koppelstelle (11), welche zur Befestigung einer Zusatzfeder (12) eingerichtet ist, wobei durch die Zusatzfeder (12) bei Befestigung an der zweiten Koppelstelle (11) in der Ruhelage des Steuerhebels (7) die Rückhaltekraft der Fesselfeder (9) verstärkt ist. Die Erfindung betrifft weiterhin ein Installationsschaltgerät mit einem solchen elektromagnetischen Auslösesystem.

The invention relates to an electromagnetic tripping system (1) for a circuit breaker, comprising a magnet system (2) with striker (45), a contact lever (5) rotatably mounted about a housing-fixed axis (4), pivotable about a pivot axis (6) mounted control lever (7) having a first coupling point (8) on which a fetlock spring (9) engages with its first end (10), wherein the restraining force of the restraining spring acts on the control lever (7) in its rest position, and wherein the Control lever (7) under the action of the striker (45) from its rest position against the restraining force of the restraining spring (9) is pivoted into its release position, wherein between the contact lever (5) and the control lever (7) has a coupling, which is a pivoting movement of the control lever (7) transmits in a pivoting movement of the contact lever (5). The control lever (7) has a second coupling point (11), which is adapted for attachment of an additional spring (12), wherein by the additional spring (12) when attached to the second coupling point (11) in the rest position of the control lever (7), the retaining force the restraining spring (9) is reinforced. The invention further relates to a service switching device with such an electromagnetic tripping system.
