ELECTROMAGNETIC CONTACTOR

摘要

There is provided an electromagnetic contactor wherein it is possible to reduce the size thereof while securing a sufficient arc extinguishing function regardless of the orientation of current flowing through contact portions. The electromagnetic contactor includes a contact device (100) wherein a pair of fixed contacts (111) and (112) and a movable contact (130) disposed so as to be able to come into and out of contact with the pair of fixed contacts (111) and (112) are housed in a contact housing case (102) formed from an insulating material, wherein arc extinguishing permanent magnets (143) and (144) whose mutually opposing magnetic pole faces are magnetized with the same polarity are disposed on respective inner peripheral surfaces of the contact housing case (102) along the movable contact (130) so as to be brought near to the movable contact (130).
