The present invention describes an air circuit breaker including, in combination, a rotational shaft connected with a motor, a cam which rotates in one direction through a ratchet by a handle operation to accumulate energy in an energy accumulating spring for contact closure, an engaging part provided on the outer periphery of the rotational shaft, and a latch which slides on and along the engaging part of the rotational shaft such that the latch means remains disengaged from the engaging part when the cam is rotated by the handle operation so that the rotational shaft remains stationary, and which causes the cam to rotate together with the rotational shaft by engaging the engaging part of the rotational shaft when the rotational shaft is rotated in one and the same direction by the driving motor.
