Claims

[Scope of utility model registration request]

Permanent magnets corresponding to the normally open contacts of a three-pole DC electromagnetic contactor having normally open contacts on both sides of a normally closed contact are provided coaxially with each other, and an axis of each permanent magnet is provided on the outer end surface of the permanent magnet. In an arc extinguishing device for an electromagnetic contactor, which is provided with an outer magnetic pole plate protruding in the same direction and substantially perpendicular to the core, the permanent magnet is arranged on its inner end face approximately 90 degrees from the outer magnetic pole plate with the axis of the permanent magnet as the center. An arc extinguishing device for an electromagnetic contactor, characterized in that it is provided with inner magnetic pole plates that protrude in respective directions of rotation.
