Abstract

Die vorliegende Erfindung betrifft einen Schütz für Gleichstrom- und Wechselstrombetrieb mit mindestens einer Kontaktstelle mit einem Festkontakt und einem beweglichen Kontakt und mindestens einer Blasspule zur Erzeugung eines elektromagnetischen Blasfelds, wobei die Blasspule im Schließzustand des Schützes vom Stromkreis des Schützes getrennt ist und beim Öffnen des Schützes in den Stromkreis des Schützes einschaltbar ist. Es soll ein Schütz bereitgestellt werden, der eine lange Lebensdauer aufweist. Dies wird erfindungsgemäß dadurch gelöst, dass der Bereich des Schützes, in dem sich beim Öffnen der Kontakte und beim Zuschalten der Blasspule ein Lichtbogen ausbildet, eine Schutzverkleidung aus einem lichtbogenresistenten Material, z.B. Keramik, aufweist.

The present invention relates to a contactor for DC and AC operation with at least one contact point with a fixed contact and a movable contact and at least one blow coil for generating an electromagnetic blow field, the blow coil is disconnected in the closed state of the contactor from the circuit of the contactor and opening the contactor in the circuit of the contactor is switched on. It should be provided a contactor, which has a long life. This is inventively achieved in that the region of the contactor, in which forms an arc when opening the contacts and when connecting the blow coil, a protective covering of an arc-resistant material, such as ceramic having.
