Abstract

Um eine mit einfachen Mitteln realisierbare Zusatzfunktion einer Auslösevorrichtung (1a,1b) für ein Schaltgerät (2), insbesondere Schutzschaltgerät, bei Gewährleistung der konventionellen Schutzfunktion anzugeben, ist vorgesehen, dass ein elektromagnetischer Auslöser (4) neben einem kurzschlussstromsensiblen Auslöseglied (5) mit einem zugeordneten und von diesem betätigbaren Auslöseanker (8), ein von dem kurzschlussstromsensiblen Auslöseglied (5) unabhängiges, individuell ansteuerbares, weiteres Auslöseglied (6a,6b) aufweist.

Figure 00000001
In order to provide an additional function of a triggering device (1a, 1b) for a switching device (2), in particular a protective switching device, which can be implemented with simple means while ensuring the conventional protective function, it is provided that an electromagnetic trigger (4) has a triggering element (5) in addition to a short-circuit current-sensitive assigned trigger armature (8) which can be actuated by the latter, has a further trigger element (6a, 6b) which can be controlled individually and is independent of the short-circuit current sensitive trigger element (5).
