Abstract
Eine Kontaktanordnung für Fehlerstromschutzschalter mit einem beweglichen Kontakt und einem Festkontakt weisen jeweils einen Kontaktberührungsabschnitt auf. Mindestens einer der Kontakte weist einen Magneten auf, dessen Polarisierungsrichtung im wesentlichen parallel zu der Berührungsfläche der beiden Kontaktberührungsabschnitte liegt. A contact arrangement for residual current circuit breakers with a movable contact and a fixed contact each have a contact contact section. At least one of the contacts has a magnet, the direction of polarization of which is essentially parallel to the contact surface of the two contact contact sections.
