Built around the KLNR Series' single-element silver-link design, this industrial cartridge fuse combines fast-acting operation with current-limiting performance that the manufacturer says helps reduce equipment damage caused by the heating and magnetic effects of short-circuit currents. For inductive loads such as motors, transformers, and solenoids, consider normal inrush current carefully because the manufacturer states these fuses may require substantial oversizing to prevent opening during harmless inrush events.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e12A continuous current rating for circuits and equipment specifically designed around this fuse rating.\u003c\/li\u003e\n\u003cli\u003eThe Class RK1 configuration gives you a clearly defined fuse class to match the equipment's protection requirements.\u003c\/li\u003e\n\u003cli\u003eFast-acting (F) operation provides rapid response to overload and short-circuit conditions.\u003c\/li\u003e\n\u003cli\u003eA single-element silver-link design provides the fast-acting characteristics of the KLNR\/KLSR Series.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting construction helps reduce equipment damage associated with the heating and magnetic effects of short-circuit currents.\u003c\/li\u003e\n\u003cli\u003eManufacturer guidance identifies variable speed drives, rectifiers, and equipment containing surge-sensitive components as suitable applications for this fast-acting fuse family.\u003c\/li\u003e\n\u003cli\u003eIndustrial cartridge construction is designed for use with the appropriate fuse block, clip, or holder.\u003c\/li\u003e\n\u003cli\u003eThe non-indicating design means it has no built-in indicating feature.\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 KLNR012\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 250V F\/A CLASS RK1 12A\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 12A\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\u003eSeries Element Design:\u003c\/strong\u003e Single-Element, Silver Link\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 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 confirms that the KLNR012 is a Class RK1 current-limiting fuse and describes the KLNR\/KLSR family in the context of the current-limiting capability of UL Class RK1 fuses.
