Abstract

Ein Überstromauslöser für Schutzschaltgeräte, insbesondere Leitungsschutzschalter oder Motorschutzschalter, mit elektromagnetischer und thermoelektrischer Auslösung, besteht zur Erhöhung der Eigensicherheit gegen höhere Ströme aus einem wärmeleitenden rohrförmigen und mit einer Spule 12 umwickelten Tragkörper 11, der ein Anschlagende 13 und ein gegenüberliegendes erweitertes Aufnahmeende 14 für die Anlage und die radiale Lagerung einer Bimetall-Schnappscheibe 15 mit mittiger Bohrung 31 aufweist, einem in dem Tragkörper 11 befestigten Kern 16 mit einer zentralen Bohrung 18, 19, einem in dem Tragkörper 11 zwischen dessen Anschlagende 13 und dem Kern 16 bewegbaren Anker 20, und aus einem Stößel 25, der sich durch die Bohrung 31 in der Schnappscheibe 15 und die Bohrung 18, 19 im Kern 16 in Richtung des Ankers 20 erstreckt, wobei der Stößel 26 thermoelektrisch mittels der Schnappscheibe 15 über eine Verdickung 27 und elektromagnetisch mittels des Ankers 20 über einen Stößel-Betätigungsorgan 26 ausrückbar ist, und wobei im betriebsbereiten Zustand der Abstand s zwischen Anker 20 und Kern 16 höchstens dem Schnapphub der Schnappscheibe 15 entspricht.

Figure 00000001
An overcurrent release for protective switching devices, in particular miniature circuit breakers or motor protection switches, with electromagnetic and thermoelectric tripping, consists of a thermally conductive tubular support body 11 wrapped with a coil 12 to increase intrinsic safety against higher currents, which has a stop end 13 and an opposite extended receiving end 14 for the system and the radial mounting of a bimetallic snap disk 15 with a central bore 31, a core 16 fastened in the support body 11 with a central bore 18, 19, an armature 20 movable in the support body 11 between its stop end 13 and the core 16, and out a plunger 25 which extends through the bore 31 in the snap disc 15 and the bore 18, 19 in the core 16 in the direction of the armature 20, the plunger 26 being thermoelectrically by means of the snap disc 15 via a thickening 27 and electromagnetically by means of the armature 20 a st Plunger actuator 26 can be disengaged, and the distance s between armature 20 and core 16 corresponds at most to the snap stroke of the snap disk 15 in the operational state.
