It is designed for electrical circuit protection in industrial and commercial power distribution systems. The A4J10 delivers high interrupt capacity, rated at 100 kA at DC and 200 kA at AC, making it suitable for applications where fault currents can reach extreme levels. The fuse body is constructed from fiberglass and polyester materials, contributing to durability under fault conditions. This part is typically installed by licensed electricians working on panel boards, motor control centers, and disconnect switches.\u003c\/p\u003e\n\u003cp\u003eThe A4J10 is suited for use in commercial and industrial electrical systems requiring Class J fuse protection. Class J fuses are commonly used in applications demanding a compact form factor with high interrupt ratings. Typical installation scenarios include motor branch circuits, feeder circuits, and equipment protection in industrial control panels. The fast-acting response characteristic makes this fuse appropriate for protecting equipment sensitive to sustained overcurrent conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003e10 amp current rating for branch circuit and equipment protection\u003c\/li\u003e\n \u003cli\u003e200 kA AC interrupt rating for high fault current environments\u003c\/li\u003e\n \u003cli\u003e100 kA DC interrupt rating\u003c\/li\u003e\n \u003cli\u003eClass J designation ensures dimensional interchangeability with other Class J fuses\u003c\/li\u003e\n \u003cli\u003eFiberglass, GMG, and polyester body construction for reliable fault containment\u003c\/li\u003e\n \u003cli\u003eFast-acting response to protect sensitive electrical equipment from overcurrent\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for Class J cylindrical fuse applications in commercial and industrial electrical protection systems.\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). Always de-energize and lock out the circuit before removing or installing fuses. Verify that the replacement fuse amperage and class match the requirements of the overcurrent protection device and the circuit being protected. Never substitute a fuse with a higher ampere rating than what the circuit is designed for.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: J\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 10 amps\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eAC Interrupt Rating\u003c\/strong\u003e: 200 kA\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eDC Interrupt Rating\u003c\/strong\u003e: 100 kA\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 20.6 mm\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Fast-Acting\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Fiberglass, GMG, Polyester\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: A4J10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERRAZ SHAWMUT","offers":[{"title":"Default Title","offer_id":68295745536306,"sku":"A4J10","price":41.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/442247d1bf623c2d87e806637b5fce04.jpg?v=1793697791","url":"https:\/\/voomisupply.com\/products\/ferraz-shawmut-a4j10-class-j-fast-acting-fuse-10a","provider":"Voomi Supply","version":"1.0","type":"link"}
