Abstract

The invention relates to a contact arrangement, intended for a current-limiting low-voltage circuit breaker, with an elongated contact carrier (1) rotatably journalled at its mid-point, the contact carrier being arranged between two U-shaped fixed contact carriers (2) arranged spaced from each other. The fixed contact carriers have a contact leg (3) which, via a mid-portion (5), is connected to a connecting leg (4). The mid-portion exhibits a rectangular opening (6), through which the movable contact carrier (1) extends. Upon a short circuit, the contacts are opened because of electrodynamic repulsion forces between the contact legs (3) and the movable contact carrier (1). This repulsion force is reduced when the contact distance increases, but the reduction is compensated by an increasing attraction force between the movable contact carrier (1) and the connecting legs (4). In this way a greater contact-opening force is obtained during the breaking operation.
