Think motor startup or transformer inrush—situations where you don't want a brief, expected surge opening the fuse unnecessarily. This dual-element fuse is rated for 600VAC and 300VDC, providing a useful range for industrial and commercial electrical applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e50-amp continuous rating for circuits designed around a 50A protective device.\u003c\/li\u003e\n\u003cli\u003eRated up to 600VAC and 300VDC.\u003c\/li\u003e\n\u003cli\u003eClass RK5 current-limiting design helps limit damaging fault current.\u003c\/li\u003e\n\u003cli\u003eDual-element construction provides both time-delay operation and overcurrent protection.\u003c\/li\u003e\n\u003cli\u003eThe Slo-Blo \/ time-delay response allows appropriate temporary startup and inrush currents without unnecessary fuse operation.\u003c\/li\u003e\n\u003cli\u003eIndustrial cartridge format works with the appropriate fuse block, clip, or holder.\u003c\/li\u003e\n\u003cli\u003eNon-indicating fuse for applications where a built-in blown-fuse indicator isn't needed.\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\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 FLSR050\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e FLSR\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Type:\u003c\/strong\u003e Dual-Element Time-Delay Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e Class RK5\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 50A continuous\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\u003eOpening Characteristic:\u003c\/strong\u003e Slo-Blo \/ Time Lag (T) \/ Time Delay\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\u003eAdditional Manufacturer-Specified AC Interrupt Amperage:\u003c\/strong\u003e 300,000A at 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Rating:\u003c\/strong\u003e 20,000A at 300VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize \/ Construction:\u003c\/strong\u003e Industrial Cartridge\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFamily Style:\u003c\/strong\u003e Dual Element Fuse\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:\u003c\/strong\u003e Fuse Block \/ Clip \/ Holder\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePG 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 FLSR050 belongs to the Class RK5 fuse category and is designed for applications requiring the electrical characteristics of that fuse class. Its dual-element construction provides the time-delay behavior needed for loads that may briefly draw higher current during normal startup.\u003cbr\u003e\u003cbr\u003eIf a project requires specific UL, CSA, RoHS, REACH, environmental, or material-compliance documentation, check the current documentation for the exact FLSR050 catalog number. Certification and material requirements can be important for engineered projects, so they should be confirmed for the individual part rather than assumed from the product family.\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe FLSR050 makes the most sense in circuits where a standard fast-acting response may not be appropriate. Motors and transformers are good examples because both can pull considerably more current for a short period when first energized. The time-delay characteristic gives properly designed circuits room for that normal inrush while maintaining protection when an overload lasts too long, or a short circuit occurs.\u003cbr\u003e\u003cbr\u003eYou'll commonly find this type of 50A Class RK5 fuse suited to properly specified motor branch circuits, motor control equipment, transformers, industrial machinery, feeders, switchboards, service equipment, and general industrial power distribution.\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\n\u003cdiv\u003e\n\u003cblockquote\u003e\n\u003cp style=\"font-size: 12px;\"\u003e\u003cem\u003eUse of Original Equipment Manufacturer (OEM) trademarks, names, and logos is for informational and identification purposes only.
