To provide an electric switching device provided with an small-sized electric motor operating module of low power to obtain short feeding time and controlling method therefor.

A breaker is provided with a motor control device 26 acting on an operating member 18. The operating member 18 swings between a load position and a feeding position via a feeding dead point position. When the electric switching device is opened or reset by the motor control device, the operating member 18 is moved to a dividing position near the feeding dead point position to minimize feeding time. The breaker has an open dead point position. To minimize open feeding cycle time, a motor 82 drives the operating member 18 to a dividing and rotating position between the open dead point position and the load position from the feeding position.
