It protects appropriately rated electrical circuits against overloads and short circuits while allowing temporary current surges that can occur during normal equipment operation.\u003c\/p\u003e\n\u003cp\u003eHere's why that matters. Some electrical loads draw a brief burst of extra current when they're first energized. A fuse that responds too quickly may open even though the equipment is operating as intended. The LLNRK.500 uses a dual-element design with a thermally reversible, spring-loaded overload element to provide time-delay performance. This helps you reduce nuisance fuse openings caused by acceptable temporary inrush currents, without sacrificing protection against sustained overloads.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePrecise 0.5 Amp Protection\u003c\/li\u003e\n\u003cli\u003eTime-Delay Performance\u003c\/li\u003e\n\u003cli\u003eDual-Element Construction\u003c\/li\u003e\n\u003cli\u003eClass RK1 Current Limiting\u003c\/li\u003e\n\u003cli\u003eHigh AC Interrupting Capacity\u003c\/li\u003e\n\u003cli\u003eDC Circuit Capability\u003c\/li\u003e\n\u003cli\u003eLow-Resistance Design\u003c\/li\u003e\n\u003cli\u003eFlexible Fuse-Block Installation\u003c\/li\u003e\n\u003cli\u003ePotential Class H Upgrade\u003c\/li\u003e\n\u003cli\u003eNon-Indicating Construction\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 LLNRK.500\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, Dual-Element Time-Delay Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Classification:\u003c\/strong\u003e Class RK1\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current Rating:\u003c\/strong\u003e 0.5 Amps (1\/2 Amp)\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 Ratings:\u003c\/strong\u003e 200,000A and 300,000A at 250V AC, as specified by Littelfuse\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 Lag (T) \/ Time Delay\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Protective Elements:\u003c\/strong\u003e Two\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Overload Element:\u003c\/strong\u003e Thermally Reversible, Spring-Loaded\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent-Limiting:\u003c\/strong\u003e Yes\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Status 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\u003eSpecified Holder Series:\u003c\/strong\u003e LFR25030\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 manufacturer identifies the Littelfuse LLNRK.500 as a Class RK1, dual-element, current-limiting time-delay fuse in the POWR-PRO product family.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUL Listing: Specific listing details should be confirmed against current Littelfuse documentation.\u003c\/li\u003e\n\u003cli\u003eCSA Certification: Verify applicable certification status using current manufacturer records.\u003c\/li\u003e\n\u003cli\u003eRoHS Compliance: Consult the latest Littelfuse material compliance documentation.\u003c\/li\u003e\n\u003cli\u003eREACH Compliance: Consult the latest Littelfuse material compliance documentation.\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\u003eLow-Current General-Purpose Circuits\u003c\/li\u003e\n\u003cli\u003eTransformer Circuits\u003c\/li\u003e\n\u003cli\u003eSolenoid Circuits\u003c\/li\u003e\n\u003cli\u003eFluorescent Lighting Circuits\u003c\/li\u003e\n\u003cli\u003eMotor-Related Circuits\u003c\/li\u003e\n\u003cli\u003eHigh-Inrush Electrical Components\u003c\/li\u003e\n\u003cli\u003eClass H Fuse Block Upgrades\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.
