Equipment like motors, transformers, and HVAC units naturally pull a higher surge of power when they start up. The Eaton Edison ECNR40 Fuse is designed with that in mind.\u003c\/p\u003e\n\u003cp\u003eThis 40 Amp Class RK5 dual-element time-delay fuse gives equipment the space it needs to start normally without tripping unnecessarily. Instead of reacting to harmless startup surges, it stays stable during those brief moments of high inrush current. But when a real overload or short circuit happens, it responds quickly to help protect your equipment and wiring from damage.\u003c\/p\u003e\n\u003cp\u003eThat balance between flexibility and protection is what makes this fuse so widely used. It’s not just about preventing failures—it’s about keeping systems running without interruption.\u003c\/p\u003e\n\u003cp\u003eWith a 200 kAIC interrupt rating, the ECNR40 is built for demanding electrical environments where fault currents can be significant. It’s rated for 250 VAC and 125 VDC systems, making it suitable for a wide range of industrial and commercial applications. Whether it’s installed in a motor control center, distribution panel, HVAC system, or OEM equipment, it delivers consistent protection you can rely on.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e40 Amp Class RK5 fuse for commercial and industrial electrical systems\u003c\/li\u003e\n\u003cli\u003eDual-element time-delay design helps handle motor and transformer startup surges\u003c\/li\u003e\n\u003cli\u003eReduces nuisance openings during normal equipment operation\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\u003eHelps improve uptime by preventing unnecessary shutdowns\u003c\/li\u003e\n\u003cli\u003eSuitable for motors, HVAC systems, transformers, and control panels\u003c\/li\u003e\n\u003cli\u003eNon-indicating design for straightforward replacement\u003c\/li\u003e\n\u003cli\u003eDesigned for dependable performance in real-world operating conditions\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 ECNR40\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 782634507369\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 40 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 8.63 in L × 2.38 in W × 2.38 in H\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.95 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 ECNR40 is CE Marked, showing compliance with recognized safety and performance standards.
