ARC BAFFLING DEVICE

摘要

An arc baffle (100) includes a first baffle member (102) having a number of first venting holes (110) disposed therein, each being structured to receive ionized gases produced by an arcing event; a second baffle member (104) having a number of second venting holes (116) disposed therein; a section of porous material (106) disposed between the first baffle member and the second baffle member; and a cover (108) disposed adjacent the second baffle member on the opposite side of the section of porous material. The first venting holes are laterally spaced from the second venting holes by a predetermined distance (d) such that ionized gases (16) produced by the arcing event passing through one of the first venting holes must travel at minimum the predetermined distance (d) generally along the section of porous material before passing through one of the second venting holes (116).
