This fuse holder is rated for 14.4 kV nominal voltage with a maximum voltage rating of 17 kV and accommodates SM-4 refill units with a maximum continuous amperage of 200E. The unit features a snuffler design for enhanced arc suppression and is engineered for reliable overcurrent protection in utility and industrial substations. The holder utilizes precision-manufactured fusible elements with silver or pretensioned nickel-chrome construction, delivering melting time-current characteristics with only 10% total tolerance in melting current. The SM-4 fuse system employs a dual-arcing-rod mechanism with spring-and-cable assembly to rapidly interrupt fault currents while maintaining coordination with upstream protective devices. \u003cul\u003e\n\u003cli\u003eType: SM-4S Fuse Holder\u003c\/li\u003e\n\u003cli\u003eNominal Voltage: 14.4 kV\u003c\/li\u003e\n\u003cli\u003eMaximum Voltage: 17 kV\u003c\/li\u003e\n\u003cli\u003eMaximum Amperage: 200E\u003c\/li\u003e\n\u003cli\u003eRefill Unit: SM-4\u003c\/li\u003e\n\u003cli\u003eInstallation: Indoor\u003c\/li\u003e\n\u003cli\u003eDesign: Snuffler Power Fuse Holder\u003c\/li\u003e\n\u003cli\u003eApproximate Weight: 8 lb\u003c\/li\u003e\n\u003cli\u003eFusible Element: Silver or Pretensioned Nickel-Chrome\u003c\/li\u003e\n\u003cli\u003eMelting Current Tolerance: 10%\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: 86632R1\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 Holders\u003c\/li\u003e\n\u003cli\u003eType : SM-4\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 : 10 \u003c\/li\u003e\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"S\u0026C Electric","offers":[{"title":"Re-Certified","offer_id":44930960490655,"sku":"86632R1-ReCert","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0500\/2349\/7887\/files\/S_CElectric86632R1.webp?v=1761144794","url":"https:\/\/essentialparts.com\/products\/86632r1-s-c-electric-sm-4s-power-fuse-holder-14-4kv-200a-indoor","provider":"Essential Electric Supply","version":"1.0","type":"link"}
