Motors start up, transformers energize, and HVAC systems cycle throughout the day—all of which create short bursts of current that are completely normal. The Eaton Edison ECNR50 Fuse is designed specifically for those real-world conditions, giving you reliable protection without the nuisance interruptions that can slow everything down.\u003c\/p\u003e\n\u003cp\u003eThis 50 Amp Class RK5 dual-element time-delay fuse is built to distinguish between harmless startup surges and actual electrical faults. So when a motor kicks on or a transformer energizes, it holds steady instead of blowing unnecessarily. But when a true overload or short circuit happens, it reacts quickly to help protect your equipment and wiring from damage.\u003c\/p\u003e\n\u003cp\u003eThat balance is what makes it such a dependable choice in industrial and commercial environments. Less downtime, fewer unexpected shutdowns, and more consistent operation throughout the day.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e50 Amp Class RK5 fuse designed for industrial and commercial use\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 blowing during normal equipment startup\u003c\/li\u003e\n\u003cli\u003eHigh 200 kAIC interrupting rating for strong fault protection\u003c\/li\u003e\n\u003cli\u003eRated for 250 VAC and 125 VDC systems\u003c\/li\u003e\n\u003cli\u003eHelps improve uptime and reduce unnecessary service interruptions\u003c\/li\u003e\n\u003cli\u003eIdeal for motors, HVAC systems, transformers, and industrial equipment\u003c\/li\u003e\n\u003cli\u003eNon-indicating design for simple field replacement\u003c\/li\u003e\n\u003cli\u003eBuilt for dependable performance in real-world 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 ECNR50\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 782634507383\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 50 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 10.38 in L × 2.88 in W × 2.88 in H\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3.15 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 ECNR50 is CE Marked, indicating compliance with recognized international safety and performance standards.
