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.

摘要： An electromagnetic contactor has a contact device having a contact housing case housing a pair of fixed contacts and a movable contact disposed to be capable of contacting to and separating from the pair of fixed contacts, and an insulating cylinder in a bottomed tubular shape disposed on an inner peripheral surface of the contact housing case to enclose the pair of fixed contacts and the movable contact. The insulating cylinder positions an arc extinguishing permanent magnet for extinguishing an arc generated between the pair of fixed contacts and the movable contact. A magnet housing portion to protect the arc extinguishing permanent magnet from the arc is formed on an inner peripheral surface of the insulating cylinder and faces a side surface of the movable contact. An arc extinguishing space is formed on an outer side of the magnet housing portion in an extending direction of the movable contact.
