摘要： An electromagnetic contactor includes a first stationary contact having a stationary contact portion and a stationary terminal portion for connecting to a power supply; a second stationary contact having a stationary contact portion and a stationary terminal section for connecting to a load; a stationary-contact supporting case supporting the stationary terminal portions of the first and second stationary contacts to protrude the contact support casing, and maintaining a predetermined distance in between; a moving-contact portion contactable to and separable from the stationary contact portion of the first and second stationary contact and arranged in the stationary-contact supporting case; and a pair of arc-extinguishing magnets arranged in parallel to sandwich the moving-contact portion in the longitudinal direction and having same magnetic polarity at opposing magnetic pole surfaces. A driving mechanism drives the moving-contact portion contactable to and separable from the stationary contact portions of the first and second stationary contacts.

摘要： An electromagnetic contactor has a contact device including a contact housing for housing a pair of fixed contact pieces and a movable contact piece disposed to contact with and separate away from the pair of fixed contact pieces, a pair of arc-extinguishing inner permanent magnets disposed on inner peripheral surfaces of the contact housing, and a pair of arc-extinguishing outer permanent magnets disposed on outer peripheral surfaces of the contact housing at a section facing the arc-extinguishing inner permanent magnets. Magnetic pole surfaces of the arc-extinguishing inner permanent magnets are arranged in a close vicinity of the movable contact piece and are magnetized to have the same polarity facing each other. The arc-extinguishing outer permanent magnets are magnetized in the same direction as the arc-extinguishing inner permanent magnets disposed nearby and coercive force of the arc-extinguishing outer permanent magnets is greater than of that the arc-extinguishing inner permanent magnets.
