    摘要: A fusible disconnect switch device is provided. The disconnect switch a switch actuator, an actuator bias element, and a slider assembly. The switch actuator is selectively positionable between an opened position and a closed position. The actuator bias element includes a first end acting on the switch actuator and a second end coupled to the switch housing. The slider assembly is linked to the switch actuator. The slider assembly includes a first slider and a second slider each slidably movable with respect to the switch housing along a linear axis. The first slider is independently movable relative to the second slider. The actuator bias element and the slider assembly are responsive to the position of the switch actuator to effect the switch closing operation and a switch opening operation.

    摘要: A power fuse for protecting an electrical load subject to transient load current cycling events in a direct current electrical power system is provided. The power fuse includes at least one fuse element assembly that includes one or more substrates, one or more sets of weak spots, and a conductor. The weak spots are formed on the substrates, and the substrates are longitudinally spaced apart from one another along the conductor. The conductor is separately provided from the substrate and the weak spots. The conductor includes one or more strips of metal having no stamped weak spot openings therein and therefore avoiding thermal-mechanical fatigue strain in the conductor when subjected to the transient load current cycling events. The conductor includes connector sections that are attached to respective ones of the sets of weak spots, and extending sections coupling the connector sections.

    摘要: A power fuse for protecting an electrical load subject to transient load current cycling events in a direct current electrical power system is provided. The power fuse includes at least one fuse element assembly that includes an elongated planar substrate, a plurality of fusible weak spots, and a conductor. The weak spots are formed on the substrate and are longitudinally spaced from one another on the substrate. The conductor is separately provided from the substrate and the weak spots. The conductor includes a solid elongated strip of metal having no stamped weak spot openings therein and therefore avoiding thermal-mechanical fatigue strain in the conductor when subjected to the transient load current cycling events. The solid elongated strip of metal includes coplanar connector sections that are mounted to respective ones of the weak spots and obliquely extending sections bent out of plane of the connector sections to extend above the substrate.
