The Eaton Edison ECNR4 Fuse is a 4 Amp Class RK5 dual-element time-delay fuse designed to deliver dependable overcurrent protection for low-amperage circuits in commercial, industrial, and OEM applications. It’s commonly used in control systems, automation panels, transformers, and other equipment where stability and precision protection are critical.\u003c\/p\u003e\n\u003cp\u003eWhat makes this fuse especially useful is how it handles everyday electrical behavior. Many systems experience brief startup surges when power is first applied—especially control transformers, small motors, and electronic components. Instead of reacting too quickly and shutting the system down unnecessarily, the ECNR4 is designed to tolerate those short inrush conditions. Once a true overload or fault occurs, it responds quickly to help protect equipment and prevent damage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e4 Amp Class RK5 fuse for low-amperage circuit protection\u003c\/li\u003e\n\u003cli\u003eDual-element time-delay design helps handle startup inrush currents\u003c\/li\u003e\n\u003cli\u003eReduces nuisance fuse openings during normal system energization\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 applications\u003c\/li\u003e\n\u003cli\u003eIdeal for protecting sensitive control and electronic equipment\u003c\/li\u003e\n\u003cli\u003eHelps improve system uptime and reduce maintenance interruptions\u003c\/li\u003e\n\u003cli\u003eNon-indicating design for straightforward replacement\u003c\/li\u003e\n\u003cli\u003eSuitable for industrial, commercial, and OEM 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 ECNR4\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 782634507208\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 4 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 8 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 ECNR4 fuse is CE Marked, indicating compliance with applicable international safety and performance standards.
