It is designed for general-purpose overcurrent protection in industrial, commercial, and heavy-duty residential electrical systems. The dual-element construction provides time delay characteristics that allow motor inrush currents and other temporary overloads to pass without nuisance tripping, while still providing fast response to sustained fault conditions. With an interrupting rating of 20 kiloamps at DC and a bolt-on mount type, this fuse is suited for installation in fused disconnect switches and panelboards by licensed electricians.\u003c\/p\u003e\u003cp\u003eThis fuse is appropriate for branch circuit and feeder protection in applications where motor loads, HVAC compressors, or other inductive equipment require time delay overcurrent protection. The bolt-on mount design makes it compatible with standard Class RK5 fuse holders and fusible disconnect switches rated for this fuse class. Its 39.60 mm diameter and 181.00 mm overall length conform to Class RK5 dimensional standards, ensuring correct fitment in compatible equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e200-amp time delay rating handles motor inrush without nuisance tripping\u003c\/li\u003e\n\u003cli\u003eDual-element construction separates overload and short-circuit response\u003c\/li\u003e\n\u003cli\u003e20 kA interrupting rating at DC provides robust fault protection\u003c\/li\u003e\n\u003cli\u003eBolt-on mount type for secure installation in fused disconnects and panelboards\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\u003eClass RK5 form factor — physically non-interchangeable with lower-rated fuse classes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service fuse for Class RK5 fuse holders and fusible disconnect switches accepting 200-amp cartridge fuses with a 39.60 mm diameter and 181.00 mm overall length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit at the upstream disconnect before removing or installing any fuse. Use appropriately rated fuse pullers rated for this amperage — do not handle an energized fuse with bare hands or unrated tools. Verify the replacement fuse class, amperage, and voltage rating match the equipment nameplate before installation.\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: 200 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\u003eInterrupting Rating\u003c\/strong\u003e: 20 kA at DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.125 inches (181.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 1.559 inches (39.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Bolt-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.85 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\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-200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51711798968626,"sku":"FRN-R-200","price":525.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3bc40ac66af543a845451fccc41442f.jpg?v=1788479711","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-frn-r-200-rk5-200a-time-delay-fuse","provider":"Voomi Supply","version":"1.0","type":"link"}
