Abstract

Bei einem Justierverfahren für einen thermischen Überlastauslöser mit einer Anzahl von Bimetallstreifen (1) in einem mechanischen Abgriffsystem (2), das unter Bildung eines Auslöseabstands (y) mit einem Auslösemechanismus (3) in Wirkverbindung steht, wird eine Drehbewegung oder eine Linearbewegung in eine Abstandsänderung (Δy) umgesetzt. Um eine besonders einfache und zuverlässige Justierung zu ermöglichen, werden innerhalb eines nutzbaren Skalenbereichs (a,a') ein Toleranzausgleich durch Bewegung in eine Richtung und eine Auslösestromeinstellung durch Bewegung in die andere Richtung vorgenommen. Beide Einstellungen erfolgen mit dem gleichen in Form entweder eines Exzenters, eines Schnecken- bzw. Schraubengewindes oder eines Hebels ausgebildeten Ausgleichselement (9, 9'), dessen Skalenbereich (a, a') in einen einzigen Teilbereich (c, c') für die den Toleranzausgleich und in einen weiteren Teilbereich (b, b') für die Stromeinstellung unterteilt ist.

In an adjustment method for a thermal overload release with a number of bimetallic strips (1) in a mechanical tap system (2), which is operatively connected to form a release distance (y) with a release mechanism (3), a rotary movement or a linear movement becomes a change in distance (Δy) implemented. In order to enable a particularly simple and reliable adjustment, a tolerance compensation by movement in one direction and a tripping current setting by movement in the other direction are carried out within a usable scale range (a, a '). Both settings are made with the same compensation element (9, 9 ') in the form of either an eccentric, a screw or screw thread or a lever, the scale area (a, a') of which is in a single partial area (c, c ') for the the tolerance compensation and is divided into a further sub-area (b, b ') for the current setting.
