As part of the Fusetron FRN-R series, it uses a dual-element construction to distinguish between harmless startup inrush current and damaging overloads. The time-delay feature allows the initial startup surge of typical motors to pass without nuisance opening, while still opening the circuit before burnout when a sustained, dangerous overload is present. This 2-pack is sold as a unit and carries a UL Listed Class R rating with a 200,000 amp interrupting rating (AIR), making it suitable for high-fault-current environments.\u003c\/p\u003e\u003cp\u003eThis fuse is used in motor branch circuit and feeder applications across residential, commercial, and light industrial settings. It is commonly installed in fusible disconnect switches, motor control panels, and combination starters where motor overload and short-circuit protection are both required. The ferrule-end configuration is standard for the 45A rating, consistent with the FRN-R series range of 1\/10A through 60A. Licensed electricians typically specify this fuse for single-phase and three-phase motor circuits where time-delay protection is called out by the NEC or equipment manufacturer.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDual-element construction provides true time-delay operation for motor inrush tolerance\u003c\/li\u003e\n\u003cli\u003eOpens under sustained overloads to prevent motor burnout from overloads or single phasing\u003c\/li\u003e\n\u003cli\u003eUL Listed Class R with 200,000 AIR for high-fault-current protection\u003c\/li\u003e\n\u003cli\u003eFerrule-end termination appropriate for the 45A rating within the FRN-R series\u003c\/li\u003e\n\u003cli\u003eSold as a 2-pack for convenient replacement inventory\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Class R, FRN-R series time-delay cartridge fuse for use in fusible disconnect switches, motor starters, and panelboards that accept Class R or Class H ferrule-type fuse elements rated up to 250 volts.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a qualified, licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit at the disconnect or panel before removing or installing fuses. Verify that the fuseholder is rated for Class R fuses at the appropriate voltage and amperage before installation. Do not substitute a fuse with a higher amperage rating than what the circuit or equipment requires.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 45 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\u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: Class R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmp Interrupting Rating (AIR)\u003c\/strong\u003e: 200,000 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTermination Style\u003c\/strong\u003e: Ferrule end\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity\u003c\/strong\u003e: 2-pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.127 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUL Listed\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EATON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BP\/FRN-R-45\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51344995287346,"sku":"BP\/FRN-R-45","price":40.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310547890.jpg?v=1782047580","url":"https:\/\/voomisupply.com\/products\/eaton-bp-frn-r-45-45a-time-delay-cartridge-fuse-2-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
