This 70A Class RK1 fast-acting, current-limiting fuse is rated for a maximum of 600VAC and 300VDC, with an interrupting capacity of 200,000A at 600VAC and 20,000A at 300VDC. For equipment containing surge-sensitive components—such as compatible variable speed drives and rectifiers—the KLSR070's fast response can be particularly useful. Inductive loads require more careful consideration, however, because motor, solenoid, and transformer inrush can affect the suitability of a fast-acting fuse.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e70A continuous current rating for electrical equipment specifically requiring a 70-amp Class RK1 fuse.\u003c\/li\u003e\n\u003cli\u003eFast-acting (F) opening characteristic provides rapid overload and short-circuit protection.\u003c\/li\u003e\n\u003cli\u003eThe current-limiting design helps reduce damage from the heating and magnetic effects of short-circuit currents.\u003c\/li\u003e\n\u003cli\u003eSingle-element silver-link design provides the fast-acting characteristics associated with the KLSR Series.\u003c\/li\u003e\n\u003cli\u003e600VAC maximum voltage rating supports compatible AC electrical systems.\u003c\/li\u003e\n\u003cli\u003eRated for up to 300VDC in applications meeting the fuse's other electrical requirements.\u003c\/li\u003e\n\u003cli\u003eClass RK1 construction gives maintenance teams a clearly defined fuse class to verify during replacement.\u003c\/li\u003e\n\u003cli\u003eMatch the knife-blade configuration to the equipment's physical fuse connection requirements.\u003c\/li\u003e\n\u003cli\u003eThe non-indicating design means it has no integral blown-fuse indicator.\u003c\/li\u003e\n\u003cli\u003eInstalls 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 KLSR070\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 600V F\/A CLASS RK1 70A\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 70A\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 the KLSR Series as using a single-element silver-link design, providing a specific material detail for the fuse element.
