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.

摘要： A contact mechanism where a shape of at least one of a fixed contactor including a pair of fixed contact portions and a movable contactor including a pair of movable contact portions capable of contacting with and separating from the pair of fixed contact portions is set to a shape that generates a Lorentz force resisting electromagnetic repulsion in a contactor opening direction generated between the fixed contact portions and the movable contact portions when a current is applied, has the fixed contactor and the movable contactor being inserted in a current path. Magnetic bodies are disposed on at least one of the fixed contactor and the movable contactor for suppressing a force driving arcs, which are generated between the pair of fixed contact portions and the pair of movable contact portions, to the fixed contactor on the opposite side.
