Fusible element for fuses

摘要

A fusible element for use in fuse construction wherein the fusible element is made of an elongated, heat-conductive metal or alloy having regions of reduced cross sectional area, including a middle reduced region and two reduced intermediate regions, each of said reduced regions being disposed between two unreduced regions of the fusible element. The dimensions (width and length) of the reduced regions are selected to optimize the performance of the fusible elements. Another embodiment of the invention contemplates a fusible element with a plurality of reduced regions having specified relative dimensions for improved performance characteristics.
