This 500A Class RK5 time-delay fuse uses a dual-element design that allows it to handle appropriate short-duration inrush currents while still providing overcurrent protection for the circuit. It is rated for 250VAC and 125VDC and features knife-blade construction for use with compatible fuse blocks, clips, and holders. One especially useful feature is its indicating design.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e500A continuous current rating for high-current electrical applications.\u003c\/li\u003e\n\u003cli\u003eThe Class RK5 dual-element design provides time-delay performance when temporary inrush currents are expected.\u003c\/li\u003e\n\u003cli\u003eThe built-in indication helps maintenance teams quickly identify an open fuse.\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.\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 FLNR500-ID\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Catalog Number:\u003c\/strong\u003e FLNR500ID\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e FLNR_ID\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 Type:\u003c\/strong\u003e Dual Element\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current Rating:\u003c\/strong\u003e 500A\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:\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 Yes\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\u003eCompatible Holder Series:\u003c\/strong\u003e LFR25600 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 FLNR500-ID is manufactured as a Class RK5 fuse with the electrical and performance characteristics shown above.
