It is designed to protect motors, motor branch circuits, and other inductive loads from overloads and short circuits. The time-delay construction allows harmless motor inrush current to pass without nuisance tripping, while still providing fast response to genuine fault conditions. Licensed electricians and HVAC technicians install this fuse in disconnect switches, load centers, and motor control panels where Class RK5 rejection-style fusing is specified. Sold in a boxed package of 10.\u003c\/p\u003e\u003cp\u003eThis fuse is commonly installed in residential and light commercial HVAC systems, pump motors, air compressors, and refrigeration equipment where motor loads require a dual-element time-delay fuse. It fits Class RK5 rejection-style fuse holders and pull-out disconnects. The 250-volt rating makes it appropriate for single-phase and lower-voltage three-phase motor circuits. Applications include condenser unit disconnects, fan motor branch circuits, and compressor protection in packaged and split systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e30-amp continuous current rating for motor and inductive load circuits\u003c\/li\u003e\n\u003cli\u003e250-volt AC rating suitable for single-phase residential and commercial circuits\u003c\/li\u003e\n\u003cli\u003eFusetron dual-element time-delay design prevents nuisance trips on motor inrush\u003c\/li\u003e\n\u003cli\u003eType FRN-R Class RK5 rejection-style body fits rejection fuse holders only\u003c\/li\u003e\n\u003cli\u003eCartridge form factor for use in standard pull-out and blade-style disconnects\u003c\/li\u003e\n\u003cli\u003eBoxed package of 10 units for service stock and panel applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Class RK5 rejection-style cartridge fuse replacement for motor branch circuit protection in residential and light commercial HVAC, refrigeration, and pump applications requiring a 30A 250V time-delay fuse.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed electrician or qualified technician in accordance with NEC Article 240 and equipment manufacturer requirements. Always de-energize and lock out the circuit before handling or replacing fuses. Verify that the fuse holder is rated for Class RK5 rejection-style cartridge fuses before installation. Do not substitute a non-rejection or higher-amperage fuse in place of the specified FRN-R-30.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 30 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 Type\u003c\/strong\u003e: Type FRN-R Cartridge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: RK5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTime Delay\u003c\/strong\u003e: Dual-element time delay (Fusetron)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 per box\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.5 pounds\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-30\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BUSSMANN","offers":[{"title":"Default Title","offer_id":51561684369714,"sku":"FRN-R-30","price":86.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff49c0e6801eea5aa67c8b8279f6a052_07c971c6-ef27-4625-874b-5c4ee720c70c.jpg?v=1786467795","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-frn-r-30-cartridge-fuse-30a-250v","provider":"Voomi Supply","version":"1.0","type":"link"}
