Fuse link with exothermal reaction is formed by local addition of composition reacting at temperature lower than melting point of fusible metal, for more rapid interruption of excessive current

摘要

A material (2) bonded to the link has a composition reacting exothermally. On introduction of energy beyond a given limit, reaction is initiated at temperature below the melting point of the fusible conductor (1). Energy release, melts the conductor.
