Everything has to run smoothly under normal conditions and still be fully protected when something goes wrong. The Eaton Edison ECNR500 Fuse is a 500 Amp Class RK5 dual-element time-delay fuse built specifically for heavy-duty commercial and industrial applications where electrical loads are high and system reliability is critical.\u003c\/p\u003e\n\u003cp\u003eIn real-world operation, big equipment rarely runs at a perfectly steady current. Motors start, transformers energize, compressors cycle, and all of that creates brief but normal inrush currents.\u003c\/p\u003e\n\u003cp\u003eWith a 200 kAIC interrupting rating, this fuse is built for environments where fault current levels can be extremely high. It is rated for 250 VAC and 125 VDC systems, making it suitable for a wide range of industrial power distribution setups. Whether used in motor control centers, switchgear, large HVAC systems, or heavy industrial machinery, the ECNR500 is designed to support consistent, dependable performance under demanding conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e500 Amp Class RK5 fuse for high-capacity industrial electrical systems\u003c\/li\u003e\n\u003cli\u003eDual-element time-delay design helps manage motor and transformer inrush currents\u003c\/li\u003e\n\u003cli\u003eReduces nuisance fuse openings during normal startup conditions\u003c\/li\u003e\n\u003cli\u003eHigh 200 kAIC interrupting rating for strong fault-current protection\u003c\/li\u003e\n\u003cli\u003eRated for 250 VAC and 125 VDC applications\u003c\/li\u003e\n\u003cli\u003eHelps improve uptime and reduce unplanned system shutdowns\u003c\/li\u003e\n\u003cli\u003eSuitable for motors, transformers, HVAC systems, and heavy industrial loads\u003c\/li\u003e\n\u003cli\u003eNon-indicating design for straightforward field replacement\u003c\/li\u003e\n\u003cli\u003eBuilt for dependable performance in demanding electrical environments\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\u003eManufacturer:\u003c\/strong\u003e Eaton\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Edison ECNR\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e ECNR500\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 782634507550\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e RK5\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 500 A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 250 VAC \/ 125 VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupt Rating:\u003c\/strong\u003e 200 kAIC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResponse Time:\u003c\/strong\u003e 10 seconds at 500% overload\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Elements:\u003c\/strong\u003e Dual-element\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Indicator:\u003c\/strong\u003e Non-indicating\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecial Features:\u003c\/strong\u003e Non current limiting\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 2 in L × 0.56 in W × 0.56 in H\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.5 lb\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging Type:\u003c\/strong\u003e Standard\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 Eaton ECNR500 fuse is CE Marked, confirming compliance with recognized safety and performance standards.
