ABSTRACT:
A fused station protector is disclosed wherein the fuse links have precisely controlled fusing characteristics. A shrink away foam element (28) encloses a portion of the fuse link (26) to provide a potential hot spot for slight current excesses. The remainder of the fuse link is in contact with arc quenching material (27) for extinguishing potential power arcs. Thus, the protector provides a precise fusing characteristic for slight current excesses and arc quenching capability for severe current excesses.
