Claims

[Scope of utility model registration request]

A slidable member holds a fixed core around which an operating coil is wound, a movable core facing the fixed core, and a movable contact facing the fixed contact, and is pressed in a direction away from the fixed core by a tripping spring. In an electromagnetic contactor in which a movable body is housed in a housing, a movable permanent magnet is disposed on the surface of the movable body, and fixed permanent magnets are disposed on a fixed part facing the movable permanent magnet so that they repel each other. , the repulsive force of the movable permanent magnet and the fixed permanent magnet acts in a direction that moves the movable core away from the fixed core when the fixed core is in a non-excited state, and when the fixed core is energized and the movable body is moved, the repulsive force acts on the movable core in a direction that moves the movable core away from the fixed core when the fixed core is in a non-excited state, and when the fixed core is energized and the movable body is moved, An electromagnetic contactor characterized in that the movable iron core is reversed in the direction toward the fixed iron core.
