    Abstract: A fuse link for use in a fast acting current limiting fuse also exhibiting a superior arc quenching capability consisting of a thin copper ribbon placed in series with a thin silver ribbon. The copper section provides a faster heating capability to the fuse while the silver section assures a lower arcing capability. The copper section has a series of apertures along the surface thereof which apertures are semicircular in configuration at the top and bottom of the copper section and separated by a circular aperture in between located in the center of the link. The silver section has top and bottom trapezoidal apertures which are separated by a smaller diameter circular aperture at the center of the link. The copper and silver links are placed in series between fuse terminals and are connected by both a mechanical and electrical connection to afford a reliable bond between the dissimilar metals constituting each of the separate links.
