With an interrupting capacity of 10 kiloamperes (kA) at AC, this fuse provides reliable overcurrent protection where rapid response to fault conditions is critical. The RLS100 measures 7-7\/8 inches in overall length with a 1-5\/16 inch diameter, fitting standard cylindrical fuse holders of the appropriate class. Licensed electricians and maintenance electricians are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis fuse is suited for use in electrical panels, motor control centers, disconnect switches, and industrial control equipment requiring Class H fast-acting overcurrent protection. Its fast-acting response characteristic makes it appropriate for resistive load circuits and applications where downstream components need immediate protection from short-circuit and overload events. It is commonly used in commercial buildings, manufacturing facilities, and industrial process environments where 600-volt distribution systems are present.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003eFast-acting fuse action for immediate response to overcurrent and short-circuit conditions\u003c\/li\u003e\n \u003cli\u003e100 amp continuous current rating\u003c\/li\u003e\n \u003cli\u003e600 volt AC rating for use in standard North American distribution systems\u003c\/li\u003e\n \u003cli\u003e10 kA interrupting capacity at AC\u003c\/li\u003e\n \u003cli\u003eCylindrical form factor: 7-7\/8 inches OAL x 1-5\/16 inches diameter\u003c\/li\u003e\n \u003cli\u003eClass H designation for use in compatible cylindrical fuse holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for cylindrical Class H fast-acting fuses used in standard 600-volt industrial and commercial electrical equipment with holders rated for the specified dimensions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit at the upstream disconnect before removing or installing any fuse. Verify that the fuse holder is rated for the voltage, amperage, and physical dimensions of this fuse before installation. Do not substitute a fuse of a different ampere rating or class as a replacement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 100 amps\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 volts AC\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity\u003c\/strong\u003e: 10 kA at AC\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: H\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Fast-Acting\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 7-7\/8 inches\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1-5\/16 inches\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FERRAZ SHAWMUT\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: RLS100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERRAZ SHAWMUT","offers":[{"title":"Default Title","offer_id":68295845282098,"sku":"RLS100","price":30.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/57df611f94d943fa225e0db0525cf7e8.jpg?v=1793698073","url":"https:\/\/voomisupply.com\/products\/ferraz-shawmut-rls100-cylindrical-fast-acting-fuse-100a","provider":"Voomi Supply","version":"1.0","type":"link"}
