This 125A Class RK5 dual-element fuse features a Slo-Blo\/time-delay response, allowing it to ride through temporary inrush currents that can occur when motors and other electrical equipment start up. The FLNR125 is rated for 250VAC and 125VDC and uses a traditional knife-blade design for installation in compatible fuse blocks, clips, and holders.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e125-amp rating for circuits and equipment designed around 125A fuse protection.\u003c\/li\u003e\n\u003cli\u003eClass RK5, dual-element construction combines overcurrent protection with time-delay operation.\u003c\/li\u003e\n\u003cli\u003eThe Slo-Blo\/time-delay characteristic helps prevent unnecessary fuse opening during normal, short-lived startup currents.\u003c\/li\u003e\n\u003cli\u003eRated for use at up to 250VAC or 125VDC.\u003c\/li\u003e\n\u003cli\u003eKnife-blade design fits the appropriate fuse blocks, clips, and holders.\u003c\/li\u003e\n\u003cli\u003eSuitable for use with the LFR25200 Series holder.\u003c\/li\u003e\n\u003cli\u003eNon-indicating design keeps the construction straightforward for applications where visual fuse indication 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 FLNR125\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e FLNR\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 125A\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\u003eFamily Style:\u003c\/strong\u003e Dual Element Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum AC Voltage:\u003c\/strong\u003e 250VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum DC Voltage:\u003c\/strong\u003e 125VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpening Type:\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 Up to 300 kA\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Rating:\u003c\/strong\u003e 20 kA\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize \/ Construction:\u003c\/strong\u003e Knife-Blade\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\u003eCompatible Holder:\u003c\/strong\u003e LFR25200 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 FLNR125 is identified as a Class RK5 fuse.

Motor circuits are a good example. Motors can pull considerably more current at startup than they do once they're running, so an appropriately selected time-delay fuse can tolerate that brief inrush while still protecting against sustained overcurrent conditions.\u003cbr\u003e\u003cbr\u003eThat same characteristic can make the FLNR125 a useful fit for transformers, industrial machinery, motor applications, control equipment, and commercial or industrial electrical distribution systems designed for Class RK5 protection.\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.
