Abstract: The invention relates to a contact arrangement, particularly intended for current-limiting low-voltage circuit breakers, with a double-break movable contact arm, the central part of which is attached to an insulating shaft which is rotatably journalled in elongated holes in stand parts on each side of the contact arm. In the closed position of the arrangement, the movable contact arm is pressed against two U-shaped fixed contact arms with the aid of two torsion springs. The contact arms have flat shape and are arranged with their broad sides facing each other. The shaft consists of two sleeve-formed holders surrounding the torsion springs. One holder exhibits a stop face for a latching member for arresting the movable contact arm in the open position.
