摘要： In an exemplary embodiment of the invention, a fuse element for a time delay fuse includes a conductive fuse element member, a fuse link formed within the member, and a heat sink coupled to the member. The heat sink draws heat from the fuse element member and prevents the fuse link from opening for an increased amount of time during high current overload conditions.

摘要： A single circuit element, referred to as a solid state rectifying fuse (SSRF), rectifies an incoming AC signal and opens the circuit if a programmed maximum current level is reached. The anode or cathode depending upon the particular application is designed with a plurality of conductors strips in electrical contact with the P or N region, respectively. Conductor strips are composed of a material that melts open if the current limit is exceeded. Conductor strips are designed to have a lower total current handling capacity than that of the PN junction so that the current is reduced or terminated before the PN junction can “short.” Depending on the desired maximum current of the SSRF, the current limit can be adjusted downward by burning out or severing some of the conductors. In this sense, it is a programmable diode.

摘要： A fuse has a fuse element (6), composed of silver, with constrictions (7) which follow one another at regular intervals, and which fuse element makes contact with a combustible element (8), preferably over its entire length. The combustible element (8) is composed of a combustion compound, which is essentially of a fuel such as guanidine or a guanidine derivative and a metal such as Mg or Al and an oxidant such as KNO3, NaNO3, NH4NO3, KClO4, NaClO4, KMnO4, the proportion of which is overstoichiometric by a factor of at least 1.1, and preferably of at least 10. The combustible compound also preferably contains a binding agent such as paraffin, a thermoplastic or an elastomer, so that it can be extruded. It has an ignition temperature of between 160° C. and 260° C. and emits more than 200 J/g of heat, so that it ignites even in the event of small overcurrents and melts the entire length of the fuse element (6).
