This power fuse unit delivers fast, positive fault interruption through high-speed arc elongation in a solid-material-lined bore and efficient deionizing action of gases generated by thermal reaction. The SMU-40 fuse unit is designed for use in SMD-40 power fuse mountings and provides reliable protection in substations and outdoor distribution systems rated up to 34.5 kV. Under maximum fault conditions, heat from the confined arc causes solid material in the arc-extinguishing chamber to undergo thermal reaction, generating turbulent gases that effectively enlarge the bore diameter for mild exhaust release. Under low-to-moderate fault conditions, the arc is extinguished in the small-diameter upper section where deionizing gases are concentrated for efficient arc extinction. \u003cul\u003e\n\u003cli\u003eAmpere Rating: 50 Amperes\u003c\/li\u003e\n\u003cli\u003eVoltage Rating: 25 kV Nominal\u003c\/li\u003e\n\u003cli\u003eMaximum Voltage: 29 kV\u003c\/li\u003e\n\u003cli\u003eFuse Unit Type: SMU-40\u003c\/li\u003e\n\u003cli\u003eApplication: Outdoor Distribution\u003c\/li\u003e\n\u003cli\u003eMounting: SMD-40 Power Fuse Mountings\u003c\/li\u003e\n\u003cli\u003eArc Extinguishing: Solid-material-lined bore with thermal reaction deionizing\u003c\/li\u003e\n\u003cli\u003eInterrupting Capability: High-speed fault interruption with transient recovery voltage matching\u003c\/li\u003e\n\u003c\/ul\u003eAt \u003cb\u003eEssential Parts\u003c\/b\u003e, we offer \u003cb\u003efast shipping\u003c\/b\u003e, \u003cb\u003elowest price\u003c\/b\u003e, and \u003cb\u003eexpert support\u003c\/b\u003e to help you get the right product every time. \t\t\t\t\t\t\t\t\t\t\u003cbr\u003e                                          \t\t\t\t\t\t\t\t\t\t\u003ch3\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003c\/h3\u003e \t\t\t\t\t\t\t\t\t\t\u003cul\u003e \t\t\t\t\t\t\t\t\t\t\t\u003cli\u003ePart Number: 823050\u003c\/li\u003e                                             \u003cli\u003eManufacturer : S\u0026amp;C Electric\u003c\/li\u003e\n\u003cli\u003eBrand : S\u0026amp;C Electric\u003c\/li\u003e\n\u003cli\u003eCategory : Fuse\u003c\/li\u003e\n\u003cli\u003eItem Subcategory : Medium Voltage\u003c\/li\u003e\n\u003cli\u003eType : SMU-40\u003c\/li\u003e\n\u003cli\u003eVoltage : 25000\u003c\/li\u003e\n\u003cli\u003eAmperage : 50\u003c\/li\u003e\n\u003cli\u003eClass Rating : SMU-40\u003c\/li\u003e\n\u003cli\u003eBarrels : 1\u003c\/li\u003e\n\u003cli\u003eVelocity : Standard\u003c\/li\u003e \t\t\t\t\t\t\t\t\t\t\u003c\/ul\u003e                                         \u003cbr\u003e                                         \u003ch3\u003e\u003cb\u003eProduct Data\u003c\/b\u003e\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eWeight : 1 \u003c\/li\u003e\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"S\u0026C Electric","offers":[{"title":"New","offer_id":45103524118687,"sku":"823050-New","price":0.0,"currency_code":"USD","in_stock":false},{"title":"Re-Certified","offer_id":45103524741279,"sku":"823050-ReCert","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0500\/2349\/7887\/files\/s-c-electric-fuse-new-823050-s-c-electric-smu-40-50-amp-25kv-power-fuse-unit-53827561717919.webp?v=1766010231","url":"https:\/\/essentialparts.com\/products\/823050-s-c-electric-smu-40-50-amp-25kv-power-fuse-unit","provider":"Essential Electric Supply","version":"1.0","type":"link"}
