This refill unit features a silver or pretensioned nickel-chrome current-responsive fusible element that delivers precise melting time-current characteristics with only 10% total tolerance in melting current. The solderless construction with brazed terminals ensures corrosion resistance and nondamageability, maintaining consistent performance regardless of age, vibration, or thermal stress. The SM-5 design achieves fast, positive fault interruption through high-speed arc elongation in the solid-material-lined bore and efficient deionizing action of gases generated by thermal reaction. \u003cul\u003e\n\u003cli\u003ePart Number: 351250R4\u003c\/li\u003e\n\u003cli\u003eManufacturer: S\u0026amp;C Electric\u003c\/li\u003e\n\u003cli\u003eAmpere Rating: 150A\u003c\/li\u003e\n\u003cli\u003eVoltage Rating: 7.2 kV Nominal\u003c\/li\u003e\n\u003cli\u003eFuse Type: SM-5 Refill Unit\u003c\/li\u003e\n\u003cli\u003eSpeed Characteristic: Very Slow\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\u003eMelting Current Tolerance: 10%\u003c\/li\u003e\n\u003cli\u003eApplication: Substations and 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: 351250R4\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\u003eVoltage : 7200\u003c\/li\u003e\n\u003cli\u003eAmperage : 150\u003c\/li\u003e\n\u003cli\u003eVelocity : Very Slow\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 : 3 \u003c\/li\u003e\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"S\u0026C Electric","offers":[{"title":"New","offer_id":45106054529183,"sku":"351250R4-New","price":0.0,"currency_code":"USD","in_stock":false},{"title":"Re-Certified","offer_id":45106054561951,"sku":"351250R4-ReCert","price":0.0,"currency_code":"USD","in_stock":false}],"url":"https:\/\/essentialparts.com\/products\/351250r4-s-c-electric-150a-7-2kv-sm-5-very-slow-fuse-refill","provider":"Essential Electric Supply","version":"1.0","type":"link"}
