This 90 Amp Class RK5 dual-element time-delay fuse is designed to protect motors, transformers, feeders, and branch circuits from damaging overloads and short circuits while allowing the brief inrush currents that naturally occur when equipment starts up. Instead of replacing fuses because of normal operating conditions, you get dependable protection that reacts when there's an actual fault—helping reduce unnecessary downtime and keeping critical equipment in service.\u003c\/p\u003e\n\u003cp\u003eBuilt for demanding commercial and industrial environments, the ECSR90 features a 600-volt AC rating and an impressive 200kA interrupting capacity, giving it the ability to safely clear high fault currents before they can damage valuable equipment. Whether you're replacing an existing Class RK5 fuse during routine maintenance or specifying components for a new installation, the Eaton ECSR90 delivers the dependable performance and long-term reliability professionals have come to expect from Eaton.\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 dual-element time-delay fuse\u003c\/li\u003e\n\u003cli\u003eHelps reduce nuisance fuse openings during motor startup and temporary inrush currents\u003c\/li\u003e\n\u003cli\u003eProtects motors, transformers, feeders, branch circuits, and power distribution equipment\u003c\/li\u003e\n\u003cli\u003eRated for 600 VAC electrical systems\u003c\/li\u003e\n\u003cli\u003eHigh 200kA interrupting capacity (kAIC) for dependable fault-current protection\u003c\/li\u003e\n\u003cli\u003eSuperior overload and cycling capabilities for demanding applications\u003c\/li\u003e\n\u003cli\u003eDual-element design balances time-delay operation with fast short-circuit response\u003c\/li\u003e\n\u003cli\u003eNon-indicating fuse construction\u003c\/li\u003e\n\u003cli\u003eCompatible with standard Class RK5 fuse holders and disconnect switches\u003c\/li\u003e\n\u003cli\u003eIdeal for commercial, industrial, and OEM electrical systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e ECSR90\u003cbr\u003e\n\u003c\/li\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 ECSR\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\u003eClass:\u003c\/strong\u003e RK5\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 90 Amps\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 600 VAC\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\u003eNumber of Elements:\u003c\/strong\u003e Dual\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\u003eFuse Indicator:\u003c\/strong\u003e Non-indicating\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecial Features:\u003c\/strong\u003e Superior overload and cycling capabilities\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging Type:\u003c\/strong\u003e Standard\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 1.5 in.
