A contact arrangement for a low-voltage circuit breaker comprises a pivotally mounted holder for two or more contact levers which are connected by flexible current leads to a fixed connecting device or connecting bar. Between the current leads, a spacer is arranged which comprises, besides a wall portion separating the current leads, lateral projections of pocket or tub-shaped form. The projections provide a seating surface for a leg of the current lead bent in loop form as well as a protective arch contiguous with the seating surface for protecting any damaged sheets of the current leads. The spacer comprising an insulating material, is provided with an opening for a joint pin provided for the pivotable suspension of the holder.

For receiving the contact levers of a contact arrangement, a holder is provided, in which the contact levers are supported so that they can be tilted relative to each other. The holder in turn can be moved in a stationary bearing strap for switching on and off. The bearing strap consists of two mirror-symmetrical angles which are assembled to each other by connecting straps at an unchangeable distance corresponding to the width of the holder. The connecting straps are preferably provided with openings into which material of the angles can be pushed by plastic deformation.
