Abstract

Die Erfindung betrifft einen elektrischer Leitungsschutzschalter, insbesondere Hauptleitungsschutzschalter, mit einem Hauptstrompfad (10, 10a), in dem sich eine Hauptkontaktstelle (13), ein erster thermischer Auslöser (12) und ein Schlagankersystem (16) zur Öffnung der Kontaktstelle ohne Mitwirkung eines Schaltschlosses (25) befinden, und mit einem parallel zur Hauptkontaktstelle (13) verlaufenden Nebenstrompfad (18, 18a), in dem sich ein Begrenzungswiderstand (20) und ein verzögerter Auslöser (21, 23) befinden. Im Nebenstrompfad (18, 18a) ist ein elektromagnetischer Auslöser (21) angeordnet, so dass der elektromagnetische Auslöser (21) und das Schlagankersystem (16) einen gemeinsamen Eisenkreis aufweisen, wobei der elektromagnetische Auslöser (21) auf das Schaltschloss (25) zur bleibenden Öffnung wenigstens der Hauptkontaktstelle (13) einwirkt, und dass der elektromagnetische Auslöser (21) Mittel (23) aufweist, die zu einer Verzögerung der Auslösung führen.

The invention relates to an electrical circuit breaker, in particular main circuit breaker, having a main current path (10, 10a) in which a main contact point (13), a first thermal release (12) and a striking armature system (16) for opening the contact point without the involvement of a switching mechanism ( 25), and with a parallel to the main contact point (13) extending Nebenstrompfad (18, 18a), in which a limiting resistor (20) and a delayed release (21, 23) are located. In the secondary current path (18, 18 a) an electromagnetic release (21) is arranged, so that the electromagnetic release (21) and the impact armature system (16) have a common iron circuit, wherein the electromagnetic release (21) on the switching mechanism (25) to the permanent Opening of at least the main contact point (13) acts, and that the electromagnetic release (21) comprises means (23) which lead to a delay of the triggering.
