Abstract
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.
