Zusammenfassung:Power fuses having filler material including hydrated zeolite material (170) and quartz sand (172) facilitates increasing power density of electrical fuses in reduced package sizes. The hydrated zeolite material releases water to cool and suppress electrical arcing conditions experienced in higher power circuitry. The fuse element (158) is formed as a planar strip (160) with apertures (162) defining areas (162) of reduced cross-section which act as weak spots to faciliate arc division. L'invention concerne des fusibles de puissance comportant un matériau de remplissage comprenant une zéolite hydratée permettant d'augmenter la densité de puissance de fusibles électriques dans des tailles de boîtier réduites. La zéolite hydratée dégage de l'eau pour produire un refroidissement et éliminer les conditions de formation d'arc électrique rencontrées dans des circuits de haute puissance.
