This cartridge fuse delivers superior current limitation to help prevent equipment damage during fault events while maintaining fast-acting response characteristics. \u003cb\u003eKTN-R-3\u003c\/b\u003e features a 70\/30 brass end cap with ferrule-to-ferrule construction and melamine glass tube body for reliable performance in industrial and commercial electrical systems. The fuse incorporates Class R rejection design, allowing it to physically and electrically replace Class H, K1, K5, and other fast-acting fuses in standard holders. With a 200 kA interrupting rating, this fuse complies with NEC Section 110.9 for large capacity systems and provides 10X better current limitation than standard fuses. \u003cul\u003e\n\u003cli\u003eAmperage Rating: 3 A\u003c\/li\u003e\n\u003cli\u003eVoltage Rating: 250 Vac\u003c\/li\u003e\n\u003cli\u003eInterrupting Rating: 200 kA Vac RMS Symmetrical\u003c\/li\u003e\n\u003cli\u003eFuse Type: Fast-Acting\u003c\/li\u003e\n\u003cli\u003eClass: RK1\u003c\/li\u003e\n\u003cli\u003eBody Style: Cartridge Fuse\u003c\/li\u003e\n\u003cli\u003eEnd Caps: 70\/30 Brass Ferrule\u003c\/li\u003e\n\u003cli\u003eMaterial: Melamine Glass Tube\u003c\/li\u003e\n\u003cli\u003eApplication: Panelboards\u003c\/li\u003e\n\u003cli\u003eUL Listed: Standard 248-12, Guide JDDZ, File E54273\u003c\/li\u003e\n\u003cli\u003eCSA Certified: Class 1422-02, File 53787\u003c\/li\u003e\n\u003cli\u003eCE Marked\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: KTN-R-3\u003c\/li\u003e                                             \u003cli\u003eManufacturer : Eaton\u003c\/li\u003e\n\u003cli\u003eBrand : Bussmann\u003c\/li\u003e\n\u003cli\u003eCategory : Fuse\u003c\/li\u003e\n\u003cli\u003eItem Subcategory : Low Voltage Fuse\u003c\/li\u003e\n\u003cli\u003eFamily : LIMITRON\u003c\/li\u003e\n\u003cli\u003eType : KTN-R\u003c\/li\u003e\n\u003cli\u003eVoltage : 250\u003c\/li\u003e\n\u003cli\u003eAmperage : 3\u003c\/li\u003e\n\u003cli\u003eAIC rating : 200kA@250V\u003c\/li\u003e\n\u003cli\u003eDiameter : 0.56\u003c\/li\u003e\n\u003cli\u003eClass Rating : RK1\u003c\/li\u003e\n\u003cli\u003eBarrels : 1\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\n\u003cli\u003eUPC : 051712407014\u003c\/li\u003e\n\u003cli\u003eGTIN : 00051712407014\u003c\/li\u003e\n\u003cli\u003eDimensions : 2 in x 0.56 in x 0.56 in (Length\/Depth x Height x Width)\u003c\/li\u003e\n\u003cli\u003eWeight : 0.1 \u003c\/li\u003e\n\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"Bussmann","offers":[{"title":"New","offer_id":45122113274015,"sku":"KTN-R-3-New","price":112.68,"currency_code":"USD","in_stock":true},{"title":"Re-Certified","offer_id":45122113306783,"sku":"KTN-R-3-ReCert","price":70.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0500\/2349\/7887\/files\/KTN-R-3.jpg?v=1711972271","url":"https:\/\/essentialparts.com\/products\/ktn-r-3-eaton-bussmann-class-rk1-250v-3a-fast-acting-fuse","provider":"Essential Electric Supply","version":"1.0","type":"link"}
