This fuse unit is designed for use in substations and outdoor distribution applications where coordinated protection is required with other protective devices. The SM-4 refill unit features a silver or pretensioned nickel-chrome current-responsive fusible element with solderless, brazed construction into terminals, delivering precise melting time-current characteristics with only 10% total tolerance in melting current. 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. \u003cul\u003e\n\u003cli\u003ePart Number: 251300R3\u003c\/li\u003e\n\u003cli\u003eManufacturer: S\u0026amp;C Electric\u003c\/li\u003e\n\u003cli\u003eFuse Type: SM-4 Refill Unit\u003c\/li\u003e\n\u003cli\u003eContinuous Current Rating: 200 amperes\u003c\/li\u003e\n\u003cli\u003eVoltage Rating: 7.2 kV nominal\u003c\/li\u003e\n\u003cli\u003eSpeed: Slow\u003c\/li\u003e\n\u003cli\u003eInterrupting Rating: 15,600 amperes RMS symmetrical\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\u003eArc-Extinguishing Medium: Solid-material-lined bore with deionizing gas generation\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: 251300R3\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 : SM-4\u003c\/li\u003e\n\u003cli\u003eVoltage : 7200\u003c\/li\u003e\n\u003cli\u003eAmperage : 200\u003c\/li\u003e\n\u003cli\u003eClass Rating : E\u003c\/li\u003e\n\u003cli\u003eVelocity : 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 : 2 \u003c\/li\u003e\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"S\u0026C Electric","offers":[{"title":"New","offer_id":45109859025055,"sku":"251300R3-New","price":0.0,"currency_code":"USD","in_stock":false},{"title":"Re-Certified","offer_id":45109859057823,"sku":"251300R3-ReCert","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0500\/2349\/7887\/files\/251300R3.png?v=1759339163","url":"https:\/\/essentialparts.com\/products\/251300r3-s-c-electric-sm-4-200e-7-2kv-slow-power-fuse","provider":"Essential Electric Supply","version":"1.0","type":"link"}
