Abstract

Das Joch (16) ist für einen mit Vorteil in einem Fehlerstrom-Schutzschalter einsetzbaren Magnetauslöser mit einem das Joch (16) und einen beweglichen Anker (8) enthaltenden magnetischen Kreis bestimmt. Es enthält zwei feststehende Polbleche (13, 14), welche unter Bildung eines magnetischen Widerstands vorgegebener Grösse durch Abstandsmittel voneinander getrennt sind. Das Joch (16) enthält ferner mindestens ein die Polbleche (13, 14) zusammenhaltendes Verbindungselement. Um eine kostengünstige Fertigung des Joches (16) in grossen Stückzahlen zu ermöglichen, sind die beiden Polbleche (13, 14) voneinander diaphragmafrei beabstandet, und sind mindestens zwei jeweils als Schweissstelle ausgeführte Verbindungselemente vorgesehen, welche die beiden Polbleche jeweils stegförmig überbrücken. Alternativ können das mindestens eine Verbindungselement und die Abstandsmittel von einer zwischen den beiden Polblechen (13, 14) angeordneten Lötschicht oder einer Klebschicht aus polymerem Material und einem in das polymere Material eingebetteten und als Abstandshalter dienenden Füllstoff gebildet sein.
