Abstract: A fixed contact mechanism for a circuit breaker is provided to improve a breaking property by increasing separation speed of a fixed arc contact and a movable arc contact through a strength of stability of a spring. The fixed arc contact(309) is connected to a movable arc contact(306) in normal, and it is separated from the movable arc contact in interruption. A guide(311) surrounds the fixed arc contact, and guides the fixed arc contact. An elastic body(313) is stretched in direction of the movable arc contact to accumulate energy in interrupting. If the fixed arc contact is separated from the movable arc contact, the fixed arc contact moves to a reverse direction of the movable arc contact by the energy of the elastic body. The linear motion guide prevents the fixed arc contact moving along the movable arc contact.
