Abstract

Einphasiger Schutzschalter mit einem Schaltwerk (2), welches zumindest von einem Überlastauslöseelement (1) betätigbar ist, wobei an den Schutzschalter zumindest ein weiterer, vorzugsweise zwei solche einphasigen Schutzschalter, derart ankoppelbar sind, daß bei Überlast an einem Schutzschalter zufolge der Kopplung eine allpolige Trennung hinsichtlich sämtlicher Schutzschalter erfolgt, und wobei gegebenenfalls eine ein Betätigungsorgan (5) und eine diesem zugeordnete Stromskala (33) aufweisende Strombereich-Einstelleinrichtung vorgesehen ist, wobei ein keilförmiges Verstellglied (4) zwischen dem Überlastauslöseelement (1) und einem auf das Schaltwerk (2) einwirkenden Bügel (3) angeordnet ist, das keilförmige Verstellglied (4) vermittels einer elastisch biegsamen Feder (13) mit einem Zwischenführungsstück (6) fest verbunden ist und das Zwischenführungsstück (6) in Arbeitsrichtung des Überlastauslöseelements (1) verschiebbar im Gehäuse des Schutzschalters gelagert ist.
