Abstract: The invention relates to a circuit breaker comprising a first and a second contact assembly, wherein one of the contact assemblies comprises contact fingers arranged in a finger cage configuration and the other contact assembly comprises a tube or rod contact. The contact fingers comprise an impact point where the tube or rod impacts the contact fingers for the first time during electrical connection establishment, and a contact zone which contacts the tube or rod when the electrical connection is established. The contact zone comprises two contact points separated from one another and arranged on a line which is perpendicular to the longitudinal axis.

Abstract: A high voltage interrupter unit includes a switching chamber within which at least two electric contact elements of a contact system are arranged to be moved relative to one another. The contact system includes at least one mechanical element which is at least in part not in fixed mechanical connection with either of the two contact elements. In order to increase the mechanical endurance of the contact system, the at least one mechanical element is sheathed at least in part in a layer of a synthetic, abrasion resistant material.
