Claims

[Scope of utility model registration request]

A pair of fixed contacts having main circuit terminals facing each other with a gap between them, and bridging between the main circuit terminals supported by one end of an interlocking rod that is supported so as to be able to reciprocate between the opposed fixed contacts. A movable contact, an electromagnet to which the interlocking rod is connected and controls contact and separation between the contacts of the movable contact and the fixed contact, and magnetic pole plates arranged to sandwich the contacts of the movable contact and the fixed contact, respectively; In an electromagnetic contactor equipped with an arc extinguishing device consisting of a permanent magnet coupled to a magnetic pole plate, the movable contact has a distal end portion extending in an oblique direction opposite to the fixed contact at both ends of the movable contact. A DC electromagnetic contactor characterized in that an arc conductor is provided that extends to the outside of the space sandwiched by the magnetic pole plates.
