WIPO Patent Application WO/2015/001710

Kind Code:

A1

Abstract:

　Provided is an electromagnetic contactor in which arcs, generated when a movable contactor is separated from fixed contactors, can be readily extinguished. A movable contactor (130) is disposed so as to be capable of being brought into contact with and separated from a pair of fixed contactors (111) which are disposed, at a predetermined distance from each other, in a contact housing case (102) having insulating properties. Arc-extinguishing chambers (145, 146) are formed at positions of contact between the contact of the pair of solid contactors and the contact of the movable contactor. At least the side of an inner wall surface, which comes into contact with the arc, of each of the arc extinguishing chambers is formed of a high thermal conductivity material having a higher thermal conductivity than that of a synthetic resin molding material.
