This slow-speed fuse refill unit is engineered for reliable fault interruption in medium-voltage power systems and features precision current-responsive elements for accurate melting characteristics. The SM-5 Refill Unit utilizes silver or pretensioned nickel-chrome fusible elements drawn through precision dies to very accurate diameters, with solderless construction brazed into terminals. Fast, positive fault interruption is achieved through high-speed elongation of the arc in the solid-material-lined bore and efficient deionizing action of gases generated through thermal reaction of the solid material due to the heat of the confined arc. \u003cul\u003e\n\u003cli\u003ePart Number: 260250R4\u003c\/li\u003e\n\u003cli\u003eManufacturer: S\u0026amp;C Electric\u003c\/li\u003e\n\u003cli\u003eProduct Type: SM-5 Refill Unit\u003c\/li\u003e\n\u003cli\u003eAmpere Rating: 150E\u003c\/li\u003e\n\u003cli\u003eVoltage Rating: 4.16 kV Nominal\u003c\/li\u003e\n\u003cli\u003eMaximum Voltage: 4.76 kV\u003c\/li\u003e\n\u003cli\u003eSpeed: S\u0026amp;C Slow\u003c\/li\u003e\n\u003cli\u003eTCC Curve: TCC 119-4\u003c\/li\u003e\n\u003cli\u003eFusible Element: Silver or Pretensioned Nickel-Chrome\u003c\/li\u003e\n\u003cli\u003eConstruction: Solderless, Brazed Terminals\u003c\/li\u003e\n\u003cli\u003eApplication: Outdoor Distribution\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: 260250R4\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 : Fuse Part And Accessory\u003c\/li\u003e\n\u003cli\u003eSection  : Fuse Refills\u003c\/li\u003e\n\u003cli\u003eFamily : SM-5\u003c\/li\u003e\n\u003cli\u003eType : E\u003c\/li\u003e\n\u003cli\u003eVoltage : 17000\u003c\/li\u003e\n\u003cli\u003eAmperage : 200\u003c\/li\u003e\n\u003cli\u003eMounting : Condenser\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":"Re-Certified","offer_id":45171633127583,"sku":"260250R4-ReCert","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0500\/2349\/7887\/files\/S_CElectric260250R4.png?v=1759422930","url":"https:\/\/essentialparts.com\/products\/260250r4-s-c-electric-sm-5-refill-unit-150e-4-16kv-slow-speed-fuse","provider":"Essential Electric Supply","version":"1.0","type":"link"}
