The KLSR045 is a 45-amp, fast-acting, current-limiting industrial cartridge fuse rated for up to 600VAC and 300VDC. Its single-element silver-link design provides fast-acting overload and short-circuit protection. At the same time, the current-limiting construction reduces equipment damage from the heating and magnetic effects of short-circuit currents. For replacement work, don't stop at the 45A marking—confirm the fuse class, fast-acting characteristic, voltage, interrupting capacity, cartridge configuration, and mounting requirements against the equipment specifications.\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 this specific amperage.\u003c\/li\u003e\n\u003cli\u003eClass RK1 configuration provides a clearly defined fuse class for replacement matching.\u003c\/li\u003e\n\u003cli\u003eFast-acting (F) operation provides fast overload and short-circuit protection.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting design helps reduce equipment damage caused by the heating and magnetic effects associated with short-circuit currents.\u003c\/li\u003e\n\u003cli\u003eUses the KLSR Series' single-element silver-link design.\u003c\/li\u003e\n\u003cli\u003eRated for electrical systems requiring up to 600VAC.\u003c\/li\u003e\n\u003cli\u003eAlso rated for up to 300VDC when all other circuit requirements are compatible.\u003c\/li\u003e\n\u003cli\u003eIndustrial cartridge construction gives buyers a specific physical format to match against the existing installation.\u003c\/li\u003e\n\u003cli\u003eNon-indicating design is appropriate where an integral blown-fuse indicator is not required.\u003c\/li\u003e\n\u003cli\u003eDesigned for installation in 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 KLSR045\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 600V F\/A CLASS RK1 45A\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 45A\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 300VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Interrupting Capacity:\u003c\/strong\u003e 200,000A at 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Capacity:\u003c\/strong\u003e 20,000A at 300VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eListed Interrupting Rating:\u003c\/strong\u003e 20 kA at 300VDC\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 PG Holder:\u003c\/strong\u003e LFR60060 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 having a single-element silver-link design.
