The KLNR500 is a 500A Class RK1 fast-acting, current-limiting fuse featuring the KLNR series' single-element silver-link design for overload and short-circuit protection. If you're matching a KLNR500 for replacement or equipment maintenance, check the full specification—not just \"500A\"—including Class RK1, voltage, interrupting capacity, opening characteristic, physical configuration, and holder compatibility.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e500A continuous current rating for electrical equipment designed to use a 500-amp Class RK1 fuse.\u003c\/li\u003e\n\u003cli\u003eThe fast-acting (F) opening characteristic provides a fast response to overload and short-circuit conditions.\u003c\/li\u003e\n\u003cli\u003eThe KLNR series uses a single-element silver-link design for fast-acting protection.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting construction helps reduce equipment damage caused by the heating and magnetic effects associated with short-circuit currents.\u003c\/li\u003e\n\u003cli\u003eKnife-blade construction provides the specified physical format for this 500A model.\u003c\/li\u003e\n\u003cli\u003eThe non-indicating configuration means it has no built-in blown-fuse indication feature.\u003c\/li\u003e\n\u003cli\u003eInstallation requires a compatible fuse block, clip, or holder.\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 KLNR500\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 250V F\/A CLASS RK1 500A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e KLNR\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Fast-Acting Current-Limiting Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current Rating:\u003c\/strong\u003e 500A\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\u003eAC Interrupting Rating:\u003c\/strong\u003e 200,000A at 250VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Rating:\u003c\/strong\u003e 20,000A at 125VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpening Characteristic:\u003c\/strong\u003e Fast-Acting (F)\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\u003eFamily Style:\u003c\/strong\u003e Current Limiting\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElement Design:\u003c\/strong\u003e Single-element silver link\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction \/ Size:\u003c\/strong\u003e Knife-Blade\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicating:\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\u003eSpecified Holder Series:\u003c\/strong\u003e LFR25600 Series\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 supplied manufacturer information confirms the KLNR500's Class RK1 classification, 500A current rating, fast-acting operation, current-limiting family style, single-element silver-link design, electrical ratings, knife-blade configuration, and specified mounting method.

The manufacturer identifies variable speed drives, rectifiers, and other equipment containing surge-sensitive components as examples where the fast-acting characteristics of the KLNR\/KLSR series can be useful. For an AC application, verify that the equipment requirements fall within the KLNR500's 250VAC maximum voltage and 200,000A interrupting rating at 250VAC. For DC service, match the application against its 125VDC maximum voltage and 20,000A interrupting rating at 125VDC. Also confirm physical compatibility with the specified fuse block, clips, or LFR25600 Series holder.\u003cbr\u003e\u003c\/p\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.
