Abstract
A circuit breaker is provided which can be filled with a quenching gas and which has two contact arrangements, which can be moved relative to one another and along a longitudinal axis of the circuit breaker. The contact arrangements form a arcing contact system and a rated current contact system connected electrically in parallel with it. One of the contact arrangements includes inner rated current contacts and outer rated current contacts of the rated current contact system, where the inner rated current contacts overhang the outer rated current contacts in the direction of the longitudinal axis, and the outer rated current contacts coaxially surround the inner rated current contacts. The circuit breaker has a high current carrying capability as well as a reliable switching-on and -off behavior, such as during and after the occurrence of a short-circuit current in the circuit breaker.
