The KLNR045 combines a 45-amp continuous current rating with fast-acting operation, current-limiting performance, and an industrial cartridge format. The manufacturer also identifies variable speed drives, rectifiers, and other equipment containing surge-sensitive components as applications where this fast response can be useful. Because fuse selection depends on more than current alone, confirm the fuse class, voltage, interrupting rating, opening characteristic, cartridge configuration, and mounting requirements before using the KLNR045 as a replacement.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e45A continuous current rating for equipment designed around a 45-amp fuse.\u003c\/li\u003e\n\u003cli\u003eClass RK1 configuration provides a specific fuse class for accurate replacement matching.\u003c\/li\u003e\n\u003cli\u003eFast-acting (F) operation delivers quick response to overload and short-circuit conditions.\u003c\/li\u003e\n\u003cli\u003eThe current-limiting design helps reduce equipment damage from the heating and magnetic effects of short-circuit currents.\u003c\/li\u003e\n\u003cli\u003eUses the KLNR\/KLSR family's single-element silver-link construction.\u003c\/li\u003e\n\u003cli\u003eRated for electrical systems up to 250VAC and 125VDC, subject to the equipment's requirements.\u003c\/li\u003e\n\u003cli\u003eIndustrial cartridge construction is designed for installation with a compatible fuse block, clip, or holder.\u003c\/li\u003e\n\u003cli\u003eNon-indicating design suits installations where fuse indication is not required.\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 KLNR045\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 250V F\/A CLASS RK1 45A\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 45A\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 Industrial Cartridge\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 PG Holder:\u003c\/strong\u003e LFR25060 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 identifies the KLNR045 as a Class RK1 current-limiting fuse and specifies a single-element silver-link design for the KLNR\/KLSR family.
