It carries a Class RK5 rating and delivers superior overload and cycling protection for motor branch circuits, feeder circuits, and other inductive loads. The dual element design separates the overload and short-circuit elements, allowing the fuse to ride through harmless inrush currents while still clearing dangerous fault conditions rapidly. The ECSR80 features blade end terminations on both ends and is non-indicating. Interrupting capacity is rated at 200 kAIC, making it suitable for installations with high available fault current.\u003c\/p\u003e\u003cp\u003eThis fuse is intended for use in motor circuits, HVAC equipment, and industrial control panels where time-delay performance is required to prevent nuisance opening during motor startup inrush. The 10-second delay at 500 percent of rated current gives the fuse enough tolerance for high-inrush applications without sacrificing fault protection. It fits standard Class RK5 fuseholders and fused disconnect switches commonly found in residential, commercial, and light industrial electrical systems. Licensed electricians and electrical contractors are the primary installers of this component.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80 amp continuous current rating at 600 volts AC\u003c\/li\u003e\n\u003cli\u003eTime-delay design with 10-second hold at 500 percent of rated current for motor inrush tolerance\u003c\/li\u003e\n\u003cli\u003eClass RK5 current-limiting performance with 200 kAIC interrupting rating\u003c\/li\u003e\n\u003cli\u003eDual element construction separates overload and short-circuit protection functions\u003c\/li\u003e\n\u003cli\u003eBlade end by blade end terminations for standard fuseholder compatibility\u003c\/li\u003e\n\u003cli\u003eNon-indicating design for use in applications where fuse status indication is not required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for Class RK5 dual element time-delay fuses in standard 600-volt fuseholders and fused disconnect switches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before removing or installing fuses. Verify the fuseholder is rated for Class RK5 fuses and confirm the voltage and ampere ratings match the circuit requirements before installation. Do not install a fuse with a higher ampere rating than the circuit or equipment is protected for.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 80 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: Class RK5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Time-Delay, Current-Limiting, Dual Element\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating\u003c\/strong\u003e: 200 kAIC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTime-Delay\u003c\/strong\u003e: 10 seconds at 500 percent of rated current\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTermination Style\u003c\/strong\u003e: Blade end x blade end\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicating\u003c\/strong\u003e: Non-indicating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 782634508410\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: COOPER BUSSMANN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ECSR80\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COOPER BUSSMANN","offers":[{"title":"Default Title","offer_id":51383304519986,"sku":"ECSR80","price":65.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312671823.png?v=1782592816","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-ecsr80-80a-600v-class-rk5-time-delay-fuse","provider":"Voomi Supply","version":"1.0","type":"link"}
