Abstract
A conductive heat sink is electrically interposed between a fuse and a switching apparatus within a watertight case of a network protector. The heat sink is advantageously configured to conduct current between the switching apparatus and the fuse. During operation, the skin effect causes the electricity conducted by the heat sink to flow primarily through the outer regions of the heat sink, thereby resulting in the generation of heat at the outer regions of the heat sink due to electrical resistance. The heat sink includes a core from which a plurality of fins extend. The fins conduct and convect heat away from the outer regions of the heat sink, which reduces the temperature thereof and correspondingly increases the conductivity of the outer regions of the heat sink.
