Its dual-element, time-delay design gives the circuit some breathing room during normal inrush conditions, rather than opening at every short-lived current spike. At the same time, it provides the overcurrent protection expected from an industrial cartridge fuse. The FLNR050 is rated for 250 VAC and 125 VDC, with interrupting ratings of 300 kA AC and 20 kA DC.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e50 amp rating for equipment and circuits designed around a 50A fuse\u003c\/li\u003e\n\u003cli\u003eTime-delay action allows brief, normal inrush currents without unnecessary fuse operation\u003c\/li\u003e\n\u003cli\u003eDual-element construction provides the operating characteristics needed for time-delay applications\u003c\/li\u003e\n\u003cli\u003eRated for up to 250 VAC and 125 VDC\u003c\/li\u003e\n\u003cli\u003e20 kA DC interrupting rating for compatible DC circuits\u003c\/li\u003e\n\u003cli\u003eClass RK5 design for equipment specifically requiring this fuse classification\u003c\/li\u003e\n\u003cli\u003eIndustrial cartridge construction works with compatible fuse blocks, clips, and holders\u003c\/li\u003e\n\u003cli\u003eNon-indicating configuration\u003c\/li\u003e\n\u003cli\u003eSpecified for use with the LFR25060 Series holder\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 FLNR050\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 50 A\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 250 VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum DC Voltage:\u003c\/strong\u003e 125 VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 300 kA AC; 20 kA DC\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\u003eConstruction:\u003c\/strong\u003e Industrial Cartridge\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\u003eCompatible Holder:\u003c\/strong\u003e LFR25060 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\u003eSpecific material-compliance declarations and certification listings were not included in the supplied information for the FLNR050.
