It is sold in a 2-pack carded format, making it a practical choice for service calls and routine replacements. The dual-element design provides two separate protective functions in one fuse body: it tolerates temporary motor inrush currents without nuisance tripping, while still providing fast response to sustained overloads and short circuits. Licensed electricians and HVAC technicians commonly install this fuse type in motor-circuit and equipment-protection applications where time-delay characteristics are required by the equipment manufacturer or local code.\u003c\/p\u003e\u003cp\u003eThis fuse is suited for use in residential and light commercial electrical systems, including HVAC disconnect boxes, motor branch circuits, and control panels where a Class RK5 time-delay fuse is specified. The FRN-R series designation indicates a Class RK5 rejection-style ferrule fuse, which fits only rejection-style fuse holders, preventing accidental substitution of a lower-rated fuse class. It is appropriate for circuits powering compressors, fan motors, and similar inductive loads that draw high startup current.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e35-amp continuous current rating at 250 volts AC\u003c\/li\u003e\n\u003cli\u003eDual-element construction tolerates motor inrush current while protecting against sustained overloads\u003c\/li\u003e\n\u003cli\u003eTime-delay characteristic reduces nuisance tripping on inductive motor loads\u003c\/li\u003e\n\u003cli\u003eClass RK5 rejection-style ferrule body prevents installation in non-rejection fuse holders\u003c\/li\u003e\n\u003cli\u003eSold as a 2-pack for convenient on-hand spares during service work\u003c\/li\u003e\n\u003cli\u003eCarded packaging for easy identification and storage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for Class RK5 rejection-style ferrule fuse applications requiring a 35-amp, 250-volt, time-delay cartridge fuse in residential and light commercial motor-circuit protection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician or qualified HVAC technician in accordance with NFPA 70 (NEC) requirements for motor branch-circuit protection. Always de-energize and lock out the disconnect or panel before removing or installing fuses. Use an insulated fuse puller rated for the voltage class when handling cartridge fuses. Verify that the replacement fuse holder is a rejection-style Class RK5 holder before installation, as the ferrule profile of this fuse will not seat correctly in non-rejection holders.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 35 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: Dual Element, Time Delay\u003c\/li\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: RK5\u003cli\u003e\n\u003cstrong\u003eBody Style\u003c\/strong\u003e: Ferrule Cartridge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.50 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2 fuses per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging\u003c\/strong\u003e: Carded\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: BP\/FRN-R-35\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BUSSMANN","offers":[{"title":"Default Title","offer_id":51559811350834,"sku":"BP\/FRN-R-35","price":154.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff49c0e6801eea5aa67c8b8279f6a052_53b1f31d-7a15-4999-b71b-d05181f50fbd.jpg?v=1786441720","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-bp-frn-r-35-cartridge-fuse-35a-250v","provider":"Voomi Supply","version":"1.0","type":"link"}
