Abstract
The present disclosure relates to a circuit breaker comprising: a circuit breaking part in which contact points of a fixed contact and a movable contact are in contact with each other; and an energy accumulation part for accumulating energy of a closing spring for controlling contact between the fixed contact and the movable contact, wherein the energy accumulation part comprises: an electromotive energy accumulation part; and a manual energy accumulation part separated from the electromotive energy accumulation part by a manual energy accumulation spring, and engaged with the electromotive energy accumulation part by unit of external pressure so as to transmit an inputted rotational force to the electromotive energy accumulation part, thereby accumulating the energy of the closing spring.
