A neutral pole for a multipole circuit breaker is disclosed. The circuit breaker includes a housing, a plurality of contact arms for opening and closing an electrical circuit, and an operating mechanism for driving the contact arms. The neutral pole includes a neutral housing, a conduction path within the neutral housing having a neutral arm arranged to open and close the conduction path, a bias spring configured to exert a first bias moment on the neutral arm when the conduction path is closed, a spring support configured to support the bias spring, a rotor pivotally arranged within the neutral housing and configured to displace the neutral arm and to open the conduction path, and a drive pin configured to couple the rotor to the multipole circuit breaker. The spring support is fixedly arranged at the neutral housing. The rotor is responsive to the opening and closing action of the operating mechanism of the multipole circuit breaker.
