    摘要： A high-capacity miniature cartridge fuse is provided. The fuse includes a housing, a fusible element, and first and second ferrules fabricated from aluminum alloy. The aluminum alloy ferrules is fabricated to withstand high pressure generated inside the housing as a result of arcing and to stay in place after repeated temperature and pressure changes caused by at least one of i) current or ii) arcing during short circuit events. The aluminum alloy plated with a first metal plating fabricated from a first metal different from the aluminum alloy and a second metal plating fabricated from a second metal different from the first metal, the second metal plating overlaying the first metal plating. Each of the first and second ferrules includes a side wall and an end wall, wherein the end wall includes a boss extending toward an interior of the housing.

    摘要： The subsea fuse assembly includes an enclosure filled with a dielectric fluid and provided with an equalization opening, which is sealed with a flexible element. A first electric conductor extends into the enclosure through a first lead-through positioned in a wall of the enclosure. A second electric conductor is attached to an inner surface of a wall of the enclosure. A fuse is connected between the first electric conductor and the second electric conductor within the enclosure. A third electric conductor extends outside the enclosure and is attached to an outer surface of a wall of the enclosure. An electrically conductive path is thus provided between the second electric conductor and the third electric conductor through the electrically conductive enclosure.

    摘要： A protective element includes: a fuse element cuttable by energization in a first direction; a slider made of an insulating material, including: a plate-shaped portion extending in the first direction; a shielding portion erected in a second direction on the plate-shaped portion, having a shielding-portion through hole penetrating the shielding portion; and a case made of an insulating material, including a housing portion which houses a slider and a portion of the fuse element. The housing portion includes: a shielding-portion housing space which houses the shielding portion such that the shielding portion is movable in the second direction; and a plate-shaped-portion moving space which houses the plate-shaped portion such that the plate-shaped portion is movable in the second direction Prior to the fuse element being cut, the slider and the fuse element are housed such that the fuse element is inserted into the shielding-portion through hole.

    摘要： Approaches herein provide a fuse assembly including a multi-part symmetrical housing. In some embodiments, the fuse assembly includes a core having a set of fusible elements extending between a first end fitting and a second end fitting, and a housing surrounding the core. The housing may include a first section having a first wall defining a first internal cavity, the first wall including a first slot and a first ridge, and a second section coupled to the first section, the second section having a second wall defining a second internal cavity. The second wall may include a second slot and a second ridge, wherein the first slot engages the second ridge and the second slot engages the first ridge. In some embodiments, the first and second sections define a set of openings for the first and second end fittings to extend therethrough.
