The last thing you want is a fuse opening every time. The Littelfuse LLNRK045 45 Amp, 250V Class RK1 time-delay fuse handles those temporary surges while protecting electrical equipment from dangerous overloads and short circuits. Its specially designed thermal overload element provides the time delay needed to reduce nuisance fuse opening, while its current-limiting performance helps minimize the energy released during a short circuit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e45 Amp Current Rating\u003c\/li\u003e\n\u003cli\u003e250V AC \/ 125V DC Voltage Ratings\u003c\/li\u003e\n\u003cli\u003eClass RK1 Current-Limiting Protection\u003c\/li\u003e\n\u003cli\u003eDual-Element Time-Delay Design\u003c\/li\u003e\n\u003cli\u003eReduced Nuisance Fuse Opening\u003c\/li\u003e\n\u003cli\u003eLow-Resistance Design\u003c\/li\u003e\n\u003cli\u003eClass H Fuse Block Compatibility\u003c\/li\u003e\n\u003cli\u003eFlexible Mounting Options\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Littelfuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e LLNRK045\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Series:\u003c\/strong\u003e LLNRK\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Family:\u003c\/strong\u003e POWR-PRO™\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Current-Limiting Time-Delay Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e Class RK1\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current Rating:\u003c\/strong\u003e 45 Amps\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum AC Voltage:\u003c\/strong\u003e 250V AC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum DC Voltage:\u003c\/strong\u003e 125V DC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Interrupting Rating:\u003c\/strong\u003e 300,000A at 250V AC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdditional AC Interrupting Rating:\u003c\/strong\u003e 200,000A at 250V AC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Rating:\u003c\/strong\u003e 20,000A at 125V DC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpening Characteristic:\u003c\/strong\u003e Slo-Blo \/ Time-Delay\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElement Configuration:\u003c\/strong\u003e Dual-Element\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Indication:\u003c\/strong\u003e Non-Indicating\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Method:\u003c\/strong\u003e Fuse Block \/ Clip \/ Holder\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Holder Series:\u003c\/strong\u003e LFR25060\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Fuse Block Type:\u003c\/strong\u003e Suitable for Class RK1 and existing Class H fuse blocks\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial Compliance and Certifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Littelfuse LLNRK045 belongs to the POWR-PRO Class RK1 fuse family and provides effective overload and short-circuit protection for industrial and commercial electrical systems.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial Compliance: RoHS and REACH status should be verified using current manufacturer documentation\u003c\/li\u003e\n\u003cli\u003eSafety Certifications: Applicable UL, CSA, and other approvals should be confirmed through the manufacturer's latest certification records\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIndustrial Motors\u003c\/li\u003e\n\u003cli\u003eTransformers\u003c\/li\u003e\n\u003cli\u003eService Entrance Equipment\u003c\/li\u003e\n\u003cli\u003eMain and Feeder Circuits\u003c\/li\u003e\n\u003cli\u003eGeneral-Purpose Branch Circuits\u003c\/li\u003e\n\u003cli\u003eSolenoids and Electromagnetic Equipment\u003c\/li\u003e\n\u003cli\u003eFluorescent Lighting Systems\u003c\/li\u003e\n\u003cli\u003eElectrical System Upgrades\u003c\/li\u003e\n\u003cli\u003eEquipment with High Inrush Currents\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\n\u003cdiv\u003e\n\u003cblockquote\u003e\n\u003cp style=\"font-size: 12px;\"\u003e\u003cem\u003eUse of Original Equipment Manufacturer (OEM) trademarks, names, and logos is for informational and identification purposes only.
