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.
