Abstract
A fuse includes a housing. A bus bar extends through the housing. An arc interrupter positioned inside the housing. A biasing element is compressed between the housing and the arc interrupter to bias the arc interrupter toward the bus bar to separate two portions of the bus bar during circuit interruption to mitigate arcing from one portion of the bus bar to the other portion of the bus bar. The bus bar includes a pocket defined therein wherein the bus bar is of a first material, and wherein a second material is seated within the pocket. In another aspect, a fuse includes a fuse housing and a bus bar extending through the housing. The bus bar includes a pocket defined therein.
