The Eaton Edison ECNR350 Fuse is a 350 Amp Class RK5 dual-element time-delay fuse designed for exactly that kind of environment. It’s commonly used in commercial and industrial power systems where large motors, transformers, and heavy electrical loads create both steady operating demand and occasional startup surges.\u003c\/p\u003e\n\u003cp\u003eInstead of reacting to those normal startup surges, the ECNR350 is designed to ride through them. That means motors and equipment can start up as expected without causing unnecessary fuse openings. When a true overload or short-circuit condition occurs, however, the fuse responds quickly to help protect downstream equipment and reduce the risk of system damage. It’s this balance—between flexibility during startup and fast protection during faults—that makes RK5 dual-element fuses a trusted choice in demanding electrical systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e350 Amp Class RK5 fuse for high-capacity 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 equipment startup\u003c\/li\u003e\n\u003cli\u003eHigh 200 kAIC interrupt rating for strong fault protection in demanding environments\u003c\/li\u003e\n\u003cli\u003eRated for 250 VAC and 125 VDC systems\u003c\/li\u003e\n\u003cli\u003eHelps improve system uptime and reduce unplanned maintenance\u003c\/li\u003e\n\u003cli\u003eSuitable for industrial, commercial, and heavy-duty electrical applications\u003c\/li\u003e\n\u003cli\u003eNon-indicating design for straightforward replacement in the field\u003c\/li\u003e\n\u003cli\u003eBuilt for consistent performance in high-load 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 ECNR350\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 782634507529\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 350 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\n\u003cul\u003e\n\u003cli\u003e2 in L × 0.56 in W × 0.56 in H\u003c\/li\u003e\n\u003c\/ul\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 ECNR350 fuse is CE Marked, confirming compliance with applicable international safety and performance standards.
