Abstract

Es wird ein elektromagnetischer Auslöser für ein elektrisches Schaltgerät, insbesondere einen Motorschutzschalter, mit einem Joch (31), einer Spule (34), einem Anker (35), der bei Auftreten eines bestimmten Überstromes eine Kontaktstelle direkt und/oder über ein Schaltschloß öffnet, und mit einer Fesselfeder (38) für den Anker (35) beschrieben, der an seinem aus der Spule (34) herausragenden Ende eine umlaufende Nut (36) aufweist, in die das Ende der auf Druck belastenden Schraubenfeder (38) eingreift und den Anker (35) so bis zu einem bestimmten Wert des Überstromes fesselt.

Figure 00000001
It is an electromagnetic release for an electrical switching device, in particular a motor protection switch, with a yoke (31), a coil (34), an armature (35), which opens a contact point directly and / or via a switch lock when a certain overcurrent occurs, and described with a shackle spring (38) for the armature (35), which has at its end protruding from the coil (34) a circumferential groove (36) into which the end of the compression spring (38) engages and the armature (35) captivates up to a certain value of the overcurrent.
