Abstract: A power fuse includes a housing (202), first and second conductive terminals (204, 206) extending from the housing, and at least one fatigue resistant fuse element assembly (208) connected between the first and second terminals. The fuse element assembly includes at least a first conductive plate and a second conductive plate (302-310) respectively connecting the first and second conductive terminals, and a plurality of separately provided wire bonded weak spots (312) interconnecting the first conductive plate and the second conductive plate.

Abstract: Systems and methods for detecting thermal-mechanical strain fatigue in an electrical fuse (100,200,352) include a controller (362) configured to monitor (722) at least one fuse fatigue parameter over a period of time while the fuse (100,200,352) is connected to an energized electrical power system, and based on the monitored at least one fuse fatigue parameter, the controller (722) is further configured to determine (726, 728) at least one of a consumed service life of the fuse element or a service life remaining of the fuse element.
