Abstract

  • 2.1. Bei derartigen Schaltern ist es erforderlich, die Bewegung eines Auslöseorganes mittels eines Zwischengliedes auf eine Verklinkungsstelle der Schaltmechanik zu übertragen. Dabei ist zur Anpassung der Auslöserfunktionen eine Justiermöglichkeit im Übertragungsweg vorzusehen. Mit der Erfindung soll eine einfach aufgebaute, rückwirkungsfreie Justiereinrichtung geschaffen werden.
  • 2.2. Zu diesem Zweck ist ein von einem Auslöseorgan (4) verdrehbarer Auslösehebel (3) exzentrisch auf einem einstellbaren Lagerkörper (2) schwenkbar angeordnet. Durch Verstellen des vorzugsweise umfangsseitig verzahnten Lagerkörpers (2) mittels eines Einstellwerkzeuges (7) läßt sich der auf einen Verklinkungsstift (5) der Schaltmechanik einwirkende Auslösehebel (3) auf vorgegebene Sollwertfunktionen einstellen.
  • 2.3. Die Anordnung eignet sich besonders als Justiereinrichtung für den thermischen Auslöser eines Leitungsschutzschalters.
