    Arc splitter plates erode as the result of load breaking. This constitutes normal wear. The erosion of the arc splitter plates can manifest itself as wear of the plates, a layer of soot, or small collection spots of molten metal. In case of heavy wear (severe erosion, large deposits of molten metal, etc.), the arc chutes should be replaced.
