But when it's time to replace it, matching the amperage is only part of the job. You also need the right voltage rating, fuse class, interrupting capacity, and operating characteristics. The LLNRK012 Littelfuse POWR-PRO 12 Amp Time-Delay Fuse is designed for electrical systems that require a Class RK1 current-limiting fuse with dependable overload and short-circuit protection.\u003c\/p\u003e\n\u003cp\u003eThe LLNRK012 is intended for installation in compatible fuse blocks, clips, and holders. Littelfuse identifies the LFR25030 series as a suitable holder family, making it a useful reference when checking the physical arrangement of an existing electrical assembly. The fuse also has a non-indicating design, meaning it does not provide a built-in visual signal when the fuse has opened.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e12 Amp Continuous Current Rating\u003c\/li\u003e\n\u003cli\u003e250VAC Maximum Voltage Rating\u003c\/li\u003e\n\u003cli\u003e125VDC Maximum Voltage Rating\u003c\/li\u003e\n\u003cli\u003eClass RK1 Fuse Classification\u003c\/li\u003e\n\u003cli\u003eSlo-Blo Time-Delay Operation\u003c\/li\u003e\n\u003cli\u003eCurrent-Limiting Protection\u003c\/li\u003e\n\u003cli\u003eNon-Indicating Design\u003c\/li\u003e\n\u003cli\u003eOverload Protection\u003c\/li\u003e\n\u003cli\u003eShort-Circuit Protection\u003c\/li\u003e\n\u003cli\u003eExisting Electrical System Maintenance\u003c\/li\u003e\n\u003cli\u003eForm, Fit, and Functional Replacement\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\u003eCatalog Number:\u003c\/strong\u003e LLNRK012\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Littelfuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Electrical Fuse\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\u003eSeries:\u003c\/strong\u003e LLNRK\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\u003eFuse Classification:\u003c\/strong\u003e Current-Limiting\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current Rating:\u003c\/strong\u003e 12 Amps\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum AC Voltage:\u003c\/strong\u003e 250VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum DC Voltage:\u003c\/strong\u003e 125VDC\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\u003eAC Interrupting Rating 1:\u003c\/strong\u003e 200,000 Amps at 250VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Interrupting Rating 2:\u003c\/strong\u003e 300,000 Amps at 250VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Rating:\u003c\/strong\u003e 20,000 Amps at 125VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicating Feature:\u003c\/strong\u003e No\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\u003eManufacturer-Identified 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 LLNRK012 belongs to the Littelfuse POWR-PRO LLNRK family and is identified as a Class RK1 current-limiting, time-delay fuse.
