When they start up, they can draw a sudden rush of current that may cause an unnecessary fuse opening. The Littelfuse LLNRK050 50 Amp Class RK1 time-delay fuse is designed to handle those brief surges while still protecting your equipment when a genuine electrical fault occurs. Part of the Littelfuse POWR-PRO™ series, this dual-element fuse uses a spring-loaded thermal overload element to provide the time delay needed for equipment with high startup currents.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e50 Amp Current Rating\u003c\/li\u003e\n\u003cli\u003e250V AC \/ 125V DC Ratings\u003c\/li\u003e\n\u003cli\u003eClass RK1 Current-Limiting Protection\u003c\/li\u003e\n\u003cli\u003eHigh Interrupting Capacity\u003c\/li\u003e\n\u003cli\u003eDual-Element Time-Delay Design\u003c\/li\u003e\n\u003cli\u003eFewer Nuisance Openings\u003c\/li\u003e\n\u003cli\u003eLow-Resistance Construction\u003c\/li\u003e\n\u003cli\u003eFlexible Mounting\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 LLNRK050\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 50 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 Ratings:\u003c\/strong\u003e 200,000A and 300,000A at 250V AC, as listed by the manufacturer\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\u003eFuse Block Compatibility:\u003c\/strong\u003e Suitable for Class RK1 and compatible 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 LLNRK050 is part of the POWR-PRO Class RK1 fuse family, built for electrical circuits that need dependable overload and short-circuit protection.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial Compliance: Verify RoHS and REACH status using current Littelfuse documentation.\u003c\/li\u003e\n\u003cli\u003eSafety Certifications: Confirm applicable UL, CSA, and other approvals through the manufacturer's latest certification records.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIf your installation has specific compliance requirements, check the manufacturer's current documentation before selecting the fuse.\u003c\/p\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\u003eMain and Feeder Circuits\u003c\/li\u003e\n\u003cli\u003eService Entrance Equipment\u003c\/li\u003e\n\u003cli\u003eGeneral-Purpose Circuits\u003c\/li\u003e\n\u003cli\u003eSolenoids\u003c\/li\u003e\n\u003cli\u003eFluorescent Lighting\u003c\/li\u003e\n\u003cli\u003eElectrical System 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.
