The Eaton Edison ECNR450 Fuse is a 450 Amp Class RK5 dual-element time-delay fuse built for demanding commercial and industrial environments where electrical loads are heavy, startup surges are normal, and downtime simply isn’t an option.\u003c\/p\u003e\n\u003cp\u003eIn real-world systems, large motors, transformers, compressors, and industrial machinery don’t draw power in a perfectly steady way. They pull a surge of current during startup, then settle into normal operation. The ECNR450 is designed specifically for that behavior. Instead of reacting to those harmless inrush conditions, it allows them to pass without interruption. But when a true overload or short circuit occurs, it responds quickly to help protect equipment, wiring, and downstream systems from serious damage.\u003c\/p\u003e\n\u003cp\u003eRated for 250 VAC and 125 VDC systems, this fuse fits a wide range of industrial applications, from motor control centers and main distribution panels to OEM equipment and facility-wide power systems. It’s built for consistency—helping reduce nuisance shutdowns, protect valuable equipment, and keep operations running smoothly even in demanding conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e450 Amp Class RK5 fuse designed for high-capacity electrical systems\u003c\/li\u003e\n\u003cli\u003eDual-element time-delay construction 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 protection in demanding environments\u003c\/li\u003e\n\u003cli\u003eRated for 250 VAC and 125 VDC applications\u003c\/li\u003e\n\u003cli\u003eHelps improve uptime and reduce unexpected system interruptions\u003c\/li\u003e\n\u003cli\u003eSuitable for motors, compressors, transformers, and industrial power distribution\u003c\/li\u003e\n\u003cli\u003eNon-indicating design for simple replacement and maintenance\u003c\/li\u003e\n\u003cli\u003eBuilt for dependable performance in heavy-duty electrical systems\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 ECNR450\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 782634507543\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 450 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 ECNR450 fuse is CE Marked, confirming compliance with recognized international safety and performance standards.
