Abstract
An electric operating device for a circuit breaker includes a cam which is turned in a predetermined direction by an electric motor which rotates in response to operating signals, and a slider having cam engaging portions which make engagement and disengagement every half revolution of the cam, and an opening into which the handle of the circuit breaker is inserted, the slider being slidable in the directions of the 'on' and 'off' operations of the handle. In the device, in response to the 'on' and 'off' operations, the cam engaging portions of the slider are disengaged from the cam, respectively. With the device, the tripping of the circuit breaker handle can be displayed without an intricate mechanism nor an additional space.
