摘要：
The disclosure describes an air circuit breaker comprising, in combination, a rotational shaft (104) connected with a motor, a cam (113) which rotates in one direction through a ratchet (112) by a handle operation to accumulate pressure in an energy accumulating spring for contact closure, and engaging part (122) provided on the outer periphery of the rotational shaft, and a latch (120) which slides on and along the engaging part (122) of the rotational shaft (104) when the cam (113) is rotated by said handle operation, and which causes the cam (113) to rotate together with the rotational shaft (104) in engagement with the engaging part (122) of the rotational shaft when the rotational shaft is rotated in one and the same direction by the motor driving.
