Motors start, compressors kick on, HVAC units cycle, and transformers energize—all of which create short bursts of current that are completely normal, but can be tough on standard protection devices. The Eaton Edison ECNR90 Fuse is designed specifically for that reality.\u003c\/p\u003e\n\u003cp\u003eThis 90 Amp Class RK5 dual-element time-delay fuse gives you a smarter way to handle those everyday conditions. Instead of tripping during harmless startup surges, it allows equipment to power up normally and settle into steady operation. But when something actually goes wrong—like a sustained overload or short circuit—it reacts quickly to help protect wiring, equipment, and downstream systems.\u003c\/p\u003e\n\u003cp\u003eThe dual-element time-delay construction is what makes it especially effective in the field. It separates normal startup conditions from actual fault events, so your system only shuts down when it truly needs to—not because of a brief surge during startup.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e90 Amp Class RK5 fuse designed for industrial and commercial electrical systems\u003c\/li\u003e\n\u003cli\u003eDual-element time-delay design helps handle normal motor and transformer inrush currents\u003c\/li\u003e\n\u003cli\u003eReduces nuisance fuse openings and unexpected downtime\u003c\/li\u003e\n\u003cli\u003eHigh 200 kAIC interrupting rating for strong fault protection capability\u003c\/li\u003e\n\u003cli\u003eRated for 250 VAC and 125 VDC applications\u003c\/li\u003e\n\u003cli\u003eHelps improve system uptime and operational reliability\u003c\/li\u003e\n\u003cli\u003eIdeal for motors, HVAC systems, transformers, and industrial equipment\u003c\/li\u003e\n\u003cli\u003eNon-indicating design for quick and simple field replacement\u003c\/li\u003e\n\u003cli\u003eBuilt for dependable performance in real-world operating 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 ECNR90\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 782634507420\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 90 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 5 in L × 0.81 in W × 0.81 in H\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.4 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 ECNR90 is CE Marked, confirming compliance with recognized international safety and performance standards.
