ELECTROMAGNETICALLY OPERATED DC CONTACTOR

摘要

A magnetic contactor including fixed contact sections and a pivoted contact section mounted on a conductor having a pivot edge on which the pivot section is mounted. Spring means for holding the pivot section against the pivot edge. A movable contact mounted on a movable conductor. Electromagnetic means for moving the movable conductor to the closed position comprising an armature. Kickout spring means connected to the assembly of the armature and the movable conductor for facilitating separaton of the contact when the electromagnetic means is deenergized. An arc chute adjacent to the stationary and movable contacts, magnetic blowout means adjacent to the stationary and movable contacts for moving an arc from the contacts into the arc chute when the contacts are separated. The device embodying the invention is a compact, low cost, single pole, DC magnetic contactor having an increased continuous current rating and increased interrupting capacity relative to conventional contactors of a given size or manufacturing cost.
