Part of the KLNR Series, it uses a single-element, silver-link design and carries a maximum rating of 250VAC and 125VDC. Its current-limiting performance also helps reduce equipment damage from the heating and magnetic effects of short-circuit currents. One detail matters when choosing this fuse: KLNR003 is fast-acting, not time-delay. The manufacturer cautions that KLNR\/KLSR fuses used with inductive loads such as motors, solenoids, and transformers may need to be greatly oversized to avoid opening during harmless inrush currents. For that reason, don't match on the 3A rating alone—confirm the fuse class, opening characteristic, voltage, interrupting rating, physical format, and equipment requirements before replacing it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e3A continuous current rating for equipment specifically designed around this amperage and fuse configuration.\u003c\/li\u003e\n\u003cli\u003eFast-acting (F) response provides fast overload and short-circuit protection.\u003c\/li\u003e\n\u003cli\u003eClass RK1 fuse configuration provides an important compatibility point when matching a replacement.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting design helps reduce equipment damage caused by the heating and magnetic effects of short-circuit currents.\u003c\/li\u003e\n\u003cli\u003eUses the KLNR\/KLSR Series' single-element, silver-link design.\u003c\/li\u003e\n\u003cli\u003eThe manufacturer identifies variable speed drives, rectifiers, and other surge-sensitive equipment as applications that can benefit from the series' fast-acting characteristics.\u003c\/li\u003e\n\u003cli\u003eIndustrial cartridge construction supports installations designed for the corresponding Class RK1 fuse format.\u003c\/li\u003e\n\u003cli\u003eNon-indicating design for applications that do not require a built-in visual status indicator.\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 KLNR003\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 250V F\/A CLASS RK1 3A\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 3A\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\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 Holder Series:\u003c\/strong\u003e LFR25030 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 KLNR003 as a Class RK1 current-limiting fuse.
