Abstract

Auslöse-Einrichtung für ein Überstrom-Abschaltgerät, wie z.B. Leitungsschutzschalter, umfassend einen ein Schaltschloß betätigenden Auslöse-Anker (1), welcher von einer von einem zu überwachenden Strom durchflossenen Spule (3) betätigbar ist, wobei der Auslöse-Anker (1) indirekt durch einen mittels zumindest einem elastischen Koppelglied (4) und gegebenenfalls einem oder mehreren Hilfsankern (11) mit dem Auslöse-Anker (1) verbundenen, von der Spule (3) unmittelbar bewegbaren Magnet-Anker (5) betätigbar ist und wobei der Auslöse-Anker (1) mit einer vorgebbaren Haltekraft (FH) in seiner Ruheposition gehalten ist.

Figure 00000001
Tripping device for an overcurrent switch-off device, such as a circuit breaker, comprising a tripping armature (1) which actuates a switch lock and which can be actuated by a coil (3) through which a current to be monitored flows, the tripping armature (1) being indirect can be actuated by means of at least one elastic coupling member (4) and optionally one or more auxiliary anchors (11) connected to the release armature (1) and directly movable by the coil (3), and the release armature (5) Anchor (1) is held in its rest position with a specifiable holding force (F H ).
