This standard-speed fuse is rated for 14.4 kV nominal (17 kV maximum) operation with a 200-ampere continuous current rating and provides reliable fault protection in industrial and utility applications. The 3E rating indicates the fuse's time-current characteristic, following S\u0026amp;C Standard Speed (TCC 153-4) coordination curves for selective protection in coordinated fuse systems. The unit features a one-time duty-cycle fault-closing capability equal to its interrupting rating and a two-time duty-cycle fault-closing capability of 13,000 amperes RMS asymmetrical, making it suitable for applications requiring repeated fault-clearing operations. \u003cul\u003e\n\u003cli\u003ePart Number: 122005R4\u003c\/li\u003e\n\u003cli\u003eManufacturer: S\u0026amp;C Electric\u003c\/li\u003e\n\u003cli\u003eVoltage Rating: 14.4 kV Nominal, 17 kV Maximum\u003c\/li\u003e\n\u003cli\u003eAmperage Rating: 200 Amperes\u003c\/li\u003e\n\u003cli\u003eFuse Type: 3E Refill Unit\u003c\/li\u003e\n\u003cli\u003eMounting: SM-4\u003c\/li\u003e\n\u003cli\u003eSpeed Characteristic: S\u0026amp;C Standard Speed (TCC 153-4)\u003c\/li\u003e\n\u003cli\u003eInterrupting Rating: 12,500 Amperes RMS Symmetrical\u003c\/li\u003e\n\u003cli\u003eDuty-Cycle Fault-Closing: One-time at rated interrupting capacity, two-time at 13,000 amperes RMS asymmetrical\u003c\/li\u003e\n\u003cli\u003eApplication: Medium-voltage power distribution and coordination with other protective devices\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: 122005R4\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-4\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":"New","offer_id":44914194841759,"sku":"122005R4-New","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0500\/2349\/7887\/files\/251300R3_68af5637-a423-461d-80ad-cb44907ffc96.png?v=1759339222","url":"https:\/\/essentialparts.com\/products\/122005r4-s-c-electric-sm-4-3e-14-4kv-200a-standard-speed-fuse","provider":"Essential Electric Supply","version":"1.0","type":"link"}
