Abstract

Die Erfindung betrifft ein thermisches Relais mit in einem Gehäuse mit mindestens einer mittels eines Deckels verschließbaren Seite untergebrachten Bimetallauslösern und einem Hilfsschalter mit Schaltwippe und einer mehrteiligen auf die Bimetallausbiegung ansprechenden, den Hilfsschalter betätigenden Übertragungseinrichtung mit einem Kompensations-Bimetallstab für die Umgebungstemperatur, sowie Bedienelementen in Gestalt eines Einstellorganes für den Strom durch Veränderung des Auslöseweges der Bimetallauslöser, eines Testorganes für das Testen der Schaltfunktion des Hilfsschalters und eines Betriebsorganes für die Rückstellung des Hilfsschalters in die Ausgangslage mittels Hand oder automatisch, wobei alle Bedienelemente (600, 620, 650) an einer Trägerplatte (60) gehaltert sind, die zusammen mit den Bedienelementen in das mit den Hilfsschalterteilen, der Übertragungseinrichtung und den Bimetallauslösern bestückte Gehäuse von der mittels des abnehmbaren Deckels (13) verschließbaren Seite einschiebbar ist.
