The invention relates to a circuit breaker comprising a first and a second contact assembly (1, 2), wherein one of the contact assemblies (1) comprises contact fingers arranged in a finger cage configuration and the other contact assembly (2) comprises a tube or rod contact. The contact fingers (1) comprise an impact point (3) where the tube or rod (2) impacts the contact fingers (1) for the first time during electrical connection establishment, and a contact zone which contacts the tube or rod (2) when the electrical connection is established. The contact zone comprises two contact points (4) separated from one another and arranged on a line which is perpendicular to the longitudinal axis (z).
