The Composite Fuse - A New Technology For Current Limiting Fuses

摘要

Results of a research program leading to the development of a new current limiting fuse device are described. The electrothermal properties of various metals were determined for optimal analysis. A new element meterial was developed. It is made from zinc and aluminum bonded together in a composite form. The composite fuse, rated general purpose, has a slow melting characteristic. A size improvement permits direct replacement for the expulsion fuse tube in distribution cutout supports.
