Hybrid current path for circuit breakers

A method for manufacturing a conductor path for a circuit breaker interrupter, the method comprising:

• press-forming a first tube made from a first metal material to form a tubular body conductor comprising a tubular end portion;
• press-forming a second tube made from a second metal material to form a tubular contact conductor comprising a tubular end portion and longitudinal contact members on an opposite side from the tubular end portion, the longitudinal contact members being adapted for making electric contact with an external contact;
• and
• pressing the tubular body conductor and the tubular contact conductor against each other in a longitudinal direction of the tubular body conductor and the tubular contact conductor so that an overlap region is produced where the tubular body conductor and the tubular contact conductor are mechanically and electrically connected to each other, wherein an outer one of the tubular end portion of the tubular body conductor and the tubular end portion of the tubular contact conductor at the overlap region comprises copper and an inner one of the tubular end portion of the tubular body conductor and the tubular end portion of the tubular contact conductor at the overlap region comprises aluminum.

A circuit breaker interrupter comprising

• an arcing contact pin;
• and
• a conductor arrangement comprising:
• a tubular body conductor comprising a first metal material;
• and
• a contact conductor comprising a second metal material, the contact conductor being at least partly tubular,
• a tubular end portion of the tubular body conductor being mechanically and electrically joined with a tubular end portion of the contact conductor in a circumferential overlap region formed by longitudinally press-fitting one of the tubular body conductor and the contact conductor into the other one of the tubular body conductor and the contact conductor, an outer one of the tubular end portion of the tubular body conductor and the tubular end portion of the contact conductor at the overlap region including copper and an inner one of the tubular end portion of the tubular body conductor and the tubular end portion of the contact conductor at the overlap region including aluminum.
