ABSTRACT:
An electromagnetic force driving actuator and a circuit breaker using the same is disclosed. The actuator comprises a casing that forms two paths having a certain length in longitudinal direction, and forms a middle wall by the two paths; a main magnetic field generation element that is allocated on the both face wall of the two paths of the casing; and a moving element that, as the middle wall is located in the center, a coil, which is bound in the orthogonal direction to longitudinal direction of the paths, is in a body that its left and right sides passes through the paths and its front and back side are exposed to outside, when forward direction or reverse direction current is provided in the coil, moves forward and backward along the longitudinal direction of the paths.
