Abstract
A circuit breaker for use in medium voltage applications includes: a housing; a first contact arranged on an end of a first contact stem that extends fixedly through the housing; a second contact arranged on an end of a second contact stem that extends axially and is movable through the housing. The circuit breaker further includes a moving device for moving the second contact between a closed position in contact with the first contact and an open position spaced apart from the first contact. A mass of the second contact is less than a mass of the first contact. The moving device includes a closing mechanism for urging the second contact to the closed position and an opening mechanism for urging the second contact to the open position. The circuit breaker further includes a reconditioning power source and a controller for providing a reconditioning current.
