    Abstract: A circuit breaker which is excellent in heat resistance and oxidation resistance in lubricating an open/close mechanism and provides an extended, stable operation, and which comprises an open/close mechanism (A) housed in an insulating case (1) and for opening/closing a movable contact (3) from/to a fixed contact (2), an engaging unit (B) engaging with the open/close mechanism (A), and a tripping mechanism (C) for freeing the engagement of the engaging unit (B) when an over-current is detected in a cable way and separating the movable contact (3) from the fixed contact (2), wherein a part of the open/close mechanism (A) is formed of a material containing iron or iron compound, and its sliding portion is provided with a lubricating oil formed by adding 1 to 5wt.% of molybdenum disulfide to an oxidation inhibitor-added phenyl ether oil.
