Class RK1 fuses provide superior current-limiting performance compared to standard Class K fuses, offering tighter rejection specifications that prevent the installation of lower-rated fuses in the same holder. The time-delay characteristic allows the fuse to tolerate brief inrush currents common in motor and transformer circuits without nuisance opening, while still providing fast response to sustained overloads and short-circuit faults. Licensed electricians and HVAC technicians install these fuses in disconnect boxes, motor branch circuits, and equipment service panels.\u003c\/p\u003e\n\u003cp\u003eThe KLNR008 is suited for residential and light commercial HVAC equipment, motors, transformers, and other inductive loads that draw startup current above the continuous run rating. It fits standard Class RK1 rejection fuse holders and fusible disconnects, making it a direct replacement in applications where Class RK1 fusing is specified by the equipment manufacturer or the authority having jurisdiction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass RK1 rejection design prevents substitution of lower-performance fuse classes in the same holder\u003c\/li\u003e\n  \u003cli\u003eTime-delay action tolerates motor inrush and transformer magnetizing currents without nuisance trips\u003c\/li\u003e\n  \u003cli\u003e8-amp continuous current rating at 250 volts AC\u003c\/li\u003e\n  \u003cli\u003eCurrent-limiting construction reduces let-through energy during fault conditions\u003c\/li\u003e\n  \u003cli\u003eFits standard Class RK1 rejection fuse holders and fusible disconnects\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Class RK1 time-delay replacement fuse for use in standard rejection-style fuse holders and fusible disconnects rated for 250 volts and 8 amps or higher.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a qualified electrician or licensed HVAC technician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize and lock out the circuit before removing or installing fuses. Verify that the replacement fuse class, voltage rating, and ampere rating match the equipment nameplate and overcurrent protection schedule. Never upsize a fuse beyond the rating specified by the equipment manufacturer or the circuit design.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmpere Rating\u003c\/strong\u003e: 8 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 250 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: RK1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResponse Type\u003c\/strong\u003e: Time-Delay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 07945828063\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LITTELFUSE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KLNR008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LITTELFUSE","offers":[{"title":"Default Title","offer_id":51383769268530,"sku":"KLNR008","price":78.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677313.jpg?v=1782606891","url":"https:\/\/voomisupply.com\/products\/littelfuse-klnr008-rk1-time-delay-fuse-8a-250v","provider":"Voomi Supply","version":"1.0","type":"link"}
