Abstract:
1. An arc baffle comprising: a first baffle member having a number of first venting holes disposed therein near a first end thereof and the remainder of the first baffle member being free of any vent holes, each of the first venting holes being structured to receive ionized gases produced by an arcing event; a second baffle member having a number of second venting holes disposed therein near a second end thereof and the remainder of the second baffle member being free of any vent holes; a section of porous material disposed between the first baffle member and the second baffle member; and a cover disposed adjacent the second baffle member on the opposite side of the section of porous material, the cover having a number of openings disposed adjacent the second venting holes, wherein the number of first venting holes are disposed offset from a centerline of the arc baffle toward a first end of the arc baffle, and wherein the number of second venting holes are disposed offset from the centerline of the arc baffle toward a second end of the arc baffle opposite from the first end such that the number of second venting holes are laterally spaced from the number of first venting holes by at least a predetermined distance, whereby ionized gases produced by the arcing event passing through the first baffle member and the second baffle member enter one of the first venting holes and then must travel at minimum the predetermined distance generally along the section of porous material and across the centerline of the arc baffle before passing through one of the second venting holes.
