It features a dual-element design that provides overload protection while allowing harmless inrush currents to pass without nuisance tripping. The fuse is indicating, giving a visual confirmation of a blown condition to speed up troubleshooting. At 2 inches overall length and 0.56 inches in diameter, it fits standard RK5 fuse holders. Licensed electricians and maintenance technicians install this fuse in branch circuit and equipment protection applications where time delay characteristics are required.\u003c\/p\u003e\u003cp\u003eThis fuse is suited for general-purpose electrical protection in both commercial and light industrial settings. Its time delay rating makes it appropriate for motor circuits, HVAC equipment, and other loads that draw elevated startup current before settling to a steady operating draw. The dual-element construction handles these transient overloads without sacrificing response speed during true fault conditions. It is mounted via a standard fuse holder and is compatible with panelboards and disconnect switches configured for RK5 class fuses.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTime delay, dual-element design tolerates motor inrush without nuisance opens\u003c\/li\u003e\n\u003cli\u003eIndicating fuse body provides clear visual blown-fuse confirmation\u003c\/li\u003e\n\u003cli\u003e10 amp rating with 20 kA interrupting capacity at DC 200 RMS\u003c\/li\u003e\n\u003cli\u003eRK5 class cartridge body fits standard RK5 fuse holders\u003c\/li\u003e\n\u003cli\u003eCE Certified, CSA C22.2 No. 248.12 Certified, and UL Listed 248-12 Class RK5\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement for RK5 class cartridge fuse positions in standard fuse holders and disconnect enclosures rated for 10 amp time delay fuses.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Always de-energize and lock out the circuit before removing or installing a fuse. Verify that the replacement fuse amp rating, class, and interrupting rating match the circuit requirements before reinstalling. Do not substitute a fuse of a higher amp rating to resolve repeated opens without first identifying the root cause of the overload.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: RK5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 10 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Timing\u003c\/strong\u003e: Time Delay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Body Type\u003c\/strong\u003e: Cartridge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Elements\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicating\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity\u003c\/strong\u003e: 20 kA at DC 200 RMS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches (50.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 0.56 inches (14.30 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Fuse Holder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: CE Certified; CSA C22.2 No. 248.12 Class 1422-02 File 53787 Certified; UL Listed 248-12 Class RK5 Guide JDDZ File E4273\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 39121605\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: COOPER BUSSMANN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FRN-R-10ID\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51714939355442,"sku":"FRN-R-10ID","price":168.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe12c7cff2db9d398b394f139a198254.jpg?v=1788508128","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-frn-r-10id-time-delay-fuse-10a-rk5","provider":"Voomi Supply","version":"1.0","type":"link"}
