Abstract: An apparatus includes an electrical assembly (e.g., a contactor) configured to be inserted into an enclosure. The electrical assembly includes at least one first contact configured to mate with at least one second contact disposed in an enclosure when the contactor assembly is inserted in the enclosure. The apparatus further includes an ejector mechanism including at least one pivoting member attached to the electrical assembly and configured to pivot about a point of attachment to the electrical assembly to apply a force to a surface of the enclosure and thereby cause movement of the electrical assembly within the enclosure. The movement of the electrical assembly caused by the ejector mechanism may disengage the at least one first contact from the at least one second contact. The electrical assembly may include a wheeled undercarriage and the at least one pivoting member may be attached to the undercarriage.

Abstract: An electrical enclosure is for an electrical apparatus. The electrical apparatus includes a number of electrical components. The electrical enclosure comprises: a frame assembly comprising a frame member having an elongated hinge side portion; a door having an elongated hinge side portion disposed parallel to and proximate the hinge side portion of the frame member, the door and the frame assembly being structured to enclose the number of electrical components; and a containment apparatus comprising a flexible barrier member coupled to the hinge side portion of the frame member and the hinge side portion of the door in order to provide a seal therebetween.
