Abstract
The circuit breaker includes a stationary contact member having a stationary contact, a movable contact member having at one end a movable contact contacting and separating from the stationary contact and having at the other end a rotational center, a case surrounding the stationary contact and the movable contact and defining a pressure accumulating space at one side of an arc generation position at which an electric arc is generated for temporarily storing a pressurized gas pressurized by the arc generated between the stationary and the movable contact upon a current interruption, and an exhaust port disposed at the other end of the arc generation position in the case so that the pressurized gas stored within the accumulation space upon the current interruption is exhausted by passing between the stationary contact and the movable contact.
