Rated for 250VAC and 125VDC, this dual-element fuse is designed to handle brief current surges without unnecessary opening, while still providing protection when an overcurrent condition persists. That makes the FLNR175 particularly useful in electrical systems where startup and inrush currents are part of normal operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e175A current rating for applications designed around a 175-amp fuse.\u003c\/li\u003e\n\u003cli\u003eClass RK5 construction for systems requiring this specific fuse class.\u003c\/li\u003e\n\u003cli\u003eTime-delay \/ Slo-Blo operation allows the fuse to ride through temporary current surges that can occur during normal equipment startup.\u003c\/li\u003e\n\u003cli\u003eDual-element design provides the operating characteristics needed for time-delay applications.\u003c\/li\u003e\n\u003cli\u003eHandles systems rated up to 250VAC or 125VDC.\u003c\/li\u003e\n\u003cli\u003eKnife-blade configuration fits compatible fuse blocks, clips, and holders.\u003c\/li\u003e\n\u003cli\u003eNon-indicating design.\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 FLNR175\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\u003eContinuous Current Rating:\u003c\/strong\u003e 175A\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\u003eOpening:\u003c\/strong\u003e Slo-Blo \/ Time Lag \/ Time Delay\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\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\u003eSpecified 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 FLNR175 is classified as a Class RK5 fuse.

Its time-delay characteristics are especially useful around equipment that can experience a short burst of higher current during startup. Instead of opening due to a normal momentary surge, the fuse can accommodate that transient condition while remaining available to protect against sustained overcurrent.\u003cbr\u003e\u003cbr\u003eDepending on the equipment specifications, applications can include motor circuits, transformers, industrial machinery, control equipment, and electrical distribution systems.
