The KLSR100 is a 100-amp, fast-acting, current-limiting fuse featuring a single-element silver-link design, knife-blade construction, and ratings up to 600VAC and 300VDC. The KLSR100 is non-indicating and mounts in a compatible fuse block, clip, or holder; the specified PG holder is the LFR60100 Series. Before replacing an existing fuse, confirm the 100A rating, Class RK1 requirement, voltage, interrupting capacity, fast-acting characteristic, knife-blade configuration, and equipment specifications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e100A continuous current rating for electrical equipment specifically requiring a 100-amp fuse.\u003c\/li\u003e\n\u003cli\u003eClass RK1 design provides a clearly defined fuse class for replacement and application matching.\u003c\/li\u003e\n\u003cli\u003eFast-acting (F) opening characteristic provides fast overload and short-circuit protection.\u003c\/li\u003e\n\u003cli\u003eBuilt with the KLSR Series' single-element silver-link design.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting construction helps reduce damage caused by the heating and magnetic effects associated with short-circuit currents.\u003c\/li\u003e\n\u003cli\u003eRated for operation in compatible circuits up to 600VAC.\u003c\/li\u003e\n\u003cli\u003eAlso rated up to 300VDC when used within the specified DC requirements.\u003c\/li\u003e\n\u003cli\u003eKnife-blade construction provides the specified physical connection style for this 100A model.\u003c\/li\u003e\n\u003cli\u003eThe non-indicating design means it has no built-in blown-fuse indicator.\u003c\/li\u003e\n\u003cli\u003eDesigned for installation using 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 KLSR100\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 600V F\/A CLASS RK1 100A\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 100A\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 Knife-Blade\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 LFR60100 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 a single-element silver-link design for KLSR Series fuses.
