Abstract

Die Erfindung betrifft einen Auslöser (1) für ein elektrisches Schaltgerät mit einem Auslösergehäuse (11) und einen im Auslösergehäuse (11) angeordneten elektromagnetischen Erreger, bestehend aus einer Erregerspule (31) und einem beweglichen Anker (33), sowie einen im Auslösergehäuse (11) angeordneten, mit dem Anker (33) wirkverbundenen Auslösemechanismus (5). Um eine wahlweise Umschaltung als Unterspannungs- oder Arbeitsstromauslöser möglichst kostengünstig zu gewährleisten, besteht der Auslösemechanismus (5) aus:
- einem translatorisch bezüglich des Auslösergehäuses (11) vor- und zurückschiebbaren Aktor (51) mit mindestens einer Aktoranbindung (511),
- einer Auslöseeinheit (54), welche einen Auslösestift (541) aufweist,
- einem Kipphebel (53), der in einer bezüglich der Bewegungsachse des Auslösestiftes (541) beabstandeten Kipphebelaufnahme (521) schwenkbar gelagert ist, wobei der Kipphebel (53) zwei freie Kipphebelarmenden aufweist, wobei das erste Kipphebelarmende mit der Aktoranbindung (511) und das zweite Kipphebelarmende mit der Auslöseeinheit (54) schwenkbar wirkverbunden ist,
- einer Stiftaufnahme (522), die die Auslöseeinheit (54) im wesentlichen senkrecht zur translatorischen Bewegungsrichtung des Aktors (51) führt,

und ist dadurch gekennzeichnet, dass die Kipphebelaufnahme (521) um eine durch den Auslösestift (541) verlaufende Achse drehbar gelagert ist und in mindestens zwei unterschiedlichen Positionen einstellbar ist.

The invention relates to a trigger (1) for an electrical switching device with a trigger housing (11) and a in the trigger housing (11) arranged electromagnetic exciter, consisting of an excitation coil (31) and a movable armature (33), and one in the trigger housing (11 ), with the armature (33) operatively connected trigger mechanism (5). To ensure an optional switchover as undervoltage or shunt release as cost-effectively as possible, the triggering mechanism (5) consists of:
a translator with respect to the trigger housing (11) forward and zurückschiebbaren actuator (51) with at least one actuator connection (511),
a trip unit (54) having a trigger pin (541),
- A rocker arm (53) which is pivotally mounted in a relative to the movement axis of the release pin (541) rocker arm receptacle (521), wherein the rocker arm (53) has two free Kipphebelarmenden, wherein the first Kipphebelarmende with the Aktoranbindung (511) and the second Kipphebelarmende pivotally operatively connected to the trip unit (54),
a pin receptacle (522) which guides the trip unit (54) substantially perpendicular to the translational direction of movement of the actuator (51),

and is characterized in that the rocker arm receptacle (521) is rotatably mounted about an axis extending through the trigger pin (541) and is adjustable in at least two different positions.
