Measuring 5 inches in overall length and 20.6 millimeters in diameter, it is designed for general-purpose overcurrent protection in industrial and commercial electrical systems. The dual-element construction provides time delay characteristics that allow motor inrush currents to pass without nuisance tripping, while still providing fast response to sustained overloads and short circuits. Licensed electricians and maintenance technicians install this fuse in fuse holders across a wide range of power distribution and motor circuit applications.\u003c\/p\u003e\n\u003cp\u003eThis fuse is suited for use in fuse holders in residential, commercial, and light industrial electrical panels and motor branch circuits where Class RK5 protection is specified. The time delay rating makes it appropriate for motor load circuits, transformer primaries, and other inductive loads that draw high inrush current at startup. Its non-indicating body means there is no external visual signal when the fuse has opened, so a continuity check is required during troubleshooting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e25-amp rating with Class RK5 time delay characteristics for motor circuit protection\u003c\/li\u003e\n  \u003cli\u003eDual-element construction tolerates inrush current while responding to sustained overloads\u003c\/li\u003e\n  \u003cli\u003eOverall length of 5 inches (127 millimeters) and 20.6-millimeter diameter for standard fuse holder fit\u003c\/li\u003e\n  \u003cli\u003eNon-indicating body — no external blown-fuse signal\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  \u003cli\u003eMounts in standard fuse holders — no special hardware required\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 requiring a 25-amp, time delay, cartridge fuse.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Always de-energize the circuit and verify zero voltage with a meter before removing or installing the fuse. Use an insulated fuse puller rated for the voltage and amperage of the circuit — never remove a cartridge fuse by hand while the circuit is live. Because this fuse is non-indicating, use a multimeter to confirm continuity when diagnosing a suspected open fuse.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: RK5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 25 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\u003eOverall Length\u003c\/strong\u003e: 5 inches (127 millimeters)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 20.6 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Fuse Holder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndicating\u003c\/strong\u003e: Non-Indicating\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating\u003c\/strong\u003e: 20 kA at DC 200 RMS\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; 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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\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: FRS-R-25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51696160571698,"sku":"FRS-R-25","price":414.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32f5cb7725a99d4bd4dd40501913a097.jpg?v=1788340278","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-frs-r-25-rk5-time-delay-fuse-25a","provider":"Voomi Supply","version":"1.0","type":"link"}
