The dual-element design provides time-delay protection with an 8-second response at 500% rated current, protecting against single-phase motor damage while allowing 130% FLA sizing for backup motor protection. Current-limiting technology reduces destructive thermal and magnetic forces during short-circuit events, with no venting of arc or molten metal. Ferrule-end connections ensure secure installation in standard fuse holders.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eKey Specifications\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAmperage Rating: 1 A\u003c\/li\u003e\n\u003cli\u003eVoltage Rating: 250 Vac, 125 Vdc\u003c\/li\u003e\n\u003cli\u003eInterrupt Rating: 300 kAIC at 250 Vac, 100 kAIC at 125 Vdc\u003c\/li\u003e\n\u003cli\u003eFuse Type: Time-delay, current-limiting\u003c\/li\u003e\n\u003cli\u003eClass: RK1\u003c\/li\u003e\n\u003cli\u003eNumber of Elements: Dual\u003c\/li\u003e\n\u003cli\u003eResponse Time: 8 seconds at 500% rated current\u003c\/li\u003e\n\u003cli\u003eConnection: Ferrule end x ferrule end\u003c\/li\u003e\n\u003cli\u003eFuse Indicator: Non-indicating\u003c\/li\u003e\n\u003cli\u003ePhysical Dimensions: 2 in length x 0.56 in height x 0.56 in width\u003c\/li\u003e\n\u003cli\u003eCertifications: cULus Listed, CE Marked\u003c\/li\u003e\n\u003cli\u003ePackaging Quantity: 10 per box\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\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.\u003c\/p\u003e \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: LPNRK1SP\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\u003c\/li\u003e\n\u003cli\u003eFamily : Low-Peak\u003c\/li\u003e\n\u003cli\u003eVoltage : 250\u003c\/li\u003e\n\u003cli\u003eAmperage : 1\u003c\/li\u003e\n\u003cli\u003eAIC rating : 300kA@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\u003cli\u003eWeight : 25 \u003c\/li\u003e\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"Bussmann","offers":[{"title":"Re-Certified","offer_id":62163847250079,"sku":"LPNRK1SP-ReCert","price":9.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0500\/2349\/7887\/files\/LPN-RK-30SP_C_576608df-d046-4015-b624-6c645e78e67c.jpg?v=1750110464","url":"https:\/\/essentialparts.com\/products\/lpnrk1sp","provider":"Essential Electric Supply","version":"1.0","type":"link"}
