ABSTRACT:
A magnetic contactor characterized by stationary and movable contacts with the stationary contact comprising at least two contact sections including a pivot section for limited movement toward the movable contact. The pivot section is mounted on a pivot edge of a first conductor and is spring biased against the pivot edge and in a position of limited movement. The movable contact is mounted on a support lever which is pivotally mounted to effect limited vertical and horizontal movement of the movable contact with respect to the stationary contact. The electromagnetic means of the contactor comprises an armature for moving the lever, and link means between the lever and the armature and includes a spring biasing structure for effecting over-travel movement of the lever. Finally, a magnetic blowout assembly and an arc chute are provided adjacent to the stationary contact zone for facilitating the interruption of an arc incurred during separation of the contacts.
