It is designed for general-purpose overcurrent protection in branch circuits and equipment circuits where a controlled response to temporary inrush currents is required. The fuse measures 2 inches in overall length and 14.3 mm in diameter, fitting standard RK5 fuse holders. With a two-element construction and non-indicating body, it provides reliable protection without a visible trip indicator. Licensed electricians and industrial maintenance technicians install this fuse in panelboards, motor control centers, and other electrical enclosures governed by NEC requirements.\u003c\/p\u003e\n\u003cp\u003eThis fuse is suited for residential, commercial, and light industrial electrical systems where Class RK5 time-delay protection is specified. Its time-delay characteristic allows it to absorb brief motor-start inrush currents or transformer magnetizing surges without nuisance opening, making it appropriate for circuits serving motors, transformers, and similar inductive loads. The non-indicating body keeps the profile compact for dense fuse holder arrangements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass RK5 time-delay fuse rated at 1.6 amps for general-purpose branch circuit protection\u003c\/li\u003e\n  \u003cli\u003eTwo-element design accommodates temporary inrush currents without nuisance opens\u003c\/li\u003e\n  \u003cli\u003eCartridge body measures 2 inches in overall length and 14.3 mm in diameter\u003c\/li\u003e\n  \u003cli\u003eNon-indicating construction maintains a low-profile fit in standard RK5 fuse holders\u003c\/li\u003e\n  \u003cli\u003eCE Certified, CSA C22.2 No. 248.12 Class 1422-02 File 53787 Certified, and UL Listed 248-12 Class RK5 Guide JDDZ File E4273\u003c\/li\u003e\n  \u003cli\u003eInterrupting rating of 20 kA at DC 200 volts RMS\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for Class RK5 cartridge fuse positions in standard fuse holders accepting a 2-inch by 14.3 mm time-delay fuse body.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and replacement of branch-circuit fuses must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit before removing or installing the fuse. Verify that the replacement fuse amperage and class match the circuit and equipment nameplate requirements. Do not substitute a higher-amperage or different-class fuse in place of the specified rating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 1.6 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: RK5\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\u003eInterrupting Rating\u003c\/strong\u003e: 20 kA at DC 200 volts RMS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches (50.8 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 14.3 mm\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: Non-Indicating\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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-1-6\/10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51694993342770,"sku":"FRN-R-1-6\/10","price":84.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c44f9ce125240596dd107674d018165e.jpg?v=1788330280","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-frn-r-1-6-10-cartridge-time-delay-fuse-rk5","provider":"Voomi Supply","version":"1.0","type":"link"}
