Abstract

Es wird ein elektromagnetischer Auslöser (10) für einen Fehlerstromschutzschalter beschrieben, der ein Gehäuse (11) aus Kunststoff, in dem ein Joch, ein Permanentmagnet, eine Spule und ein Anker, der im auslösebereiten Zustand entgegen der Kraft einer Feder vom Permanentmagneten gegen das Joch gezogen wird, untergebracht sind, aufweist. Der Anker ist mit einem aus dem Gehäuse herausragenden Stift gekoppelt, der beim Auslösevorgang auf eine Verklinkungsstelle in einem Schaltschloß des Fehlerstromschutzschalters einwirkt. Damit eine magnetische Beeinflussung des Auslösers von außen vermieden ist, ist das Gehäuse (11) von einem magnetischen Blech als Abschirmung (20) wenigstens teilweise umgeben.

Figure 00000001
An electromagnetic release (10) for a residual current circuit breaker is described, which has a housing (11) made of plastic, in which a yoke, a permanent magnet, a coil and an armature, which in the ready-to-release state counter to the force of a spring from the permanent magnet against the yoke is pulled, housed, has. The armature is coupled to a pin protruding from the housing, which acts on a latching point in a switch lock of the residual current circuit breaker during the triggering process. So that a magnetic influence on the trigger from the outside is avoided, the housing (11) is at least partially surrounded by a magnetic sheet metal as a shield (20).
