Abstract

Official abstract text for this publication.

A contactor for DC operation includes a first and a second contact that are fixed contacts and a contact bridge that has a third and a fourth contact. The contact bridge, in a closed position, provides a tactile contact between a first contact pair, which comprises the first and the third contact, and between a second contact pair, which comprises the second and the fourth contact. The contact bridge is movable via a guide along a direction of movement. A magnet arrangement is configured to generate an electromagnetic force on an electric arc, which arises on opening the contacts. The contact bridge has at least one recess, which is arranged between the guide and the third contact. The recess is configured to provide an opening at the contact bridge through which the arc, generated at the third contact, is deflected in the direction of movement of the contact bridge.
