The KLSR002 is a current-limiting industrial cartridge fuse rated for 600VAC maximum and 250VDC maximum, with fast-acting operation intended to respond quickly to overload and short-circuit conditions. For replacement work, verify the fuse class, voltage, interrupting capacity, opening characteristic, cartridge format, and mounting requirements—not simply the 2-amp rating.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2A continuous current rating for equipment specifically designed around a 2-amp Class RK1 fuse.\u003c\/li\u003e\n\u003cli\u003eThe fast-acting (F) opening characteristic provides a 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 associated with short-circuit current.\u003c\/li\u003e\n\u003cli\u003eRated for operation up to 600VAC.\u003c\/li\u003e\n\u003cli\u003eSupports DC applications up to 250VDC, subject to the equipment's specifications.\u003c\/li\u003e\n\u003cli\u003eThe KLSR series uses a single-element silver-link design to provide fast-acting performance.\u003c\/li\u003e\n\u003cli\u003eIndustrial cartridge construction provides the specified physical format for compatible fuse installations.\u003c\/li\u003e\n\u003cli\u003eDesigned for installation using a fuse block, clip, or holder.\u003c\/li\u003e\n\u003cli\u003eConfirm the non-indicating configuration when matching an existing fuse.\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 KLSR002\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 600V F\/A CLASS RK1 2A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e KLSR\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 2A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum AC Voltage:\u003c\/strong\u003e 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum DC Voltage:\u003c\/strong\u003e 250VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Interrupting Rating:\u003c\/strong\u003e 200,000A at 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Rating:\u003c\/strong\u003e 20,000A at 250VDC\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\u003eElement 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 Holder Series:\u003c\/strong\u003e LFR60030 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 specifically identifies the KLSR series as using a single-element silver-link design.
