It provides reliable short-circuit and overload protection in electrical panels, disconnect switches, and motor control equipment. The ECSR20 construction uses metal and glass materials and is rated for applications where dual-element, time-delay performance is required. Licensed electricians and electrical contractors typically specify and install this type of fuse in commercial and industrial service environments.\u003c\/p\u003e\u003cp\u003eThe ECSR20 is suited for motor branch circuits, air conditioning equipment disconnect applications, and other loads that require time-delay protection to ride through normal startup inrush current. It is installed in fusible disconnect switches and load centers that accept ECSR-style rejection-base fuses. This fuse type is a common replacement component in both new installations and retrofit service work on existing electrical equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTime-delay design accommodates motor startup inrush current without nuisance blowing\u003c\/li\u003e\n\u003cli\u003eRejection-style base limits installation to compatible ECSR-rated fuse holders, preventing installation of lower-rated fuses\u003c\/li\u003e\n\u003cli\u003eMetal and glass construction for durability and reliable fault interruption\u003c\/li\u003e\n\u003cli\u003eSuitable for branch-circuit motor protection in commercial and industrial applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement fuse for use in fusible disconnect switches and fuse holders that accept ECSR-style rejection-base fuses rated for time-delay motor-circuit protection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Always de-energize and lock out the circuit before removing or installing fuses. Use an insulated fuse puller rated for the voltage class of the circuit. Verify that the fuse holder is rated to accept ECSR rejection-style fuses before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmpere Rating\u003c\/strong\u003e: 20 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Metal, Glass\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Eaton Bussmann\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ECSR20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON BUSSMANN","offers":[{"title":"Default Title","offer_id":52045390643506,"sku":"ECSR20","price":28.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0146da88906d1695b4914c2698c57c6.jpg?v=1790030491","url":"https:\/\/voomisupply.com\/products\/eaton-bussmann-ecsr20-time-delay-fuse","provider":"Voomi Supply","version":"1.0","type":"link"}
