Instead of reacting immediately to transient conditions, the FLNR250 is designed to provide the Slo-Blo\/time-lag performance expected of this type of fuse while still protecting the circuit from damaging overcurrent. If your equipment calls for a 250A Class RK5 dual-element fuse, the FLNR250 brings together the current rating, voltage capability, time-delay operation, and physical configuration needed for a wide range of compatible applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e250A continuous current rating for compatible commercial and industrial circuits.\u003c\/li\u003e\n\u003cli\u003eClass RK5, dual-element design provides time-delay overcurrent protection.\u003c\/li\u003e\n\u003cli\u003eSlo-Blo\/time-delay operation accommodates appropriate temporary startup and inrush currents.\u003c\/li\u003e\n\u003cli\u003eRated for applications up to 250VAC or 125VDC.\u003c\/li\u003e\n\u003cli\u003eKnife-blade construction fits compatible fuse blocks, clips, and holders.\u003c\/li\u003e\n\u003cli\u003eDesigned for use with the LFR25400 Series holder family when properly matched to the application.\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 FLNR250\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 250A\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\u003eFuse Style:\u003c\/strong\u003e Dual Element\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 \/ 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\u003eConstruction:\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\u003eHolder Family:\u003c\/strong\u003e LFR25400 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 FLNR250 is a Class RK5 fuse.
