Abstract
An electromagnet device for an electromagnetic contactor is formed of a frame with an opening, a movable-contact supporter slidably disposed in the frame, a movable contact supported by the movable-contact supporter, a movable core connected to the movable-contact supporter, and a stationary core for attracting the movable core. The stationary core includes a base plate for closing the opening of the frame, at least one columnar arm core fixed to the base plate to extend therefrom, and at least one pole piece fixed to the arm core at a side opposite to the base plate. The pole piece provides attracting force to the movable core when the stationary core is energized. In the electromagnetic device, a device for partly interrupting a magnetic path of the stationary core is formed. The interrupting device reduces remanent flux in the stationary core when the stationary core is deenergized.
