This fuse provides rapid response to overcurrent events, helping protect sensitive downstream equipment from damage. Constructed with a fiberglass and polyester body with a GMG element, the A4J6 is rated for 200 kA interrupting capacity at AC and 100 kA at DC, making it suitable for systems where high fault-current levels are a concern. Licensed electricians and electrical contractors are the primary installers of Class J fuses in panel and equipment protection applications.\u003c\/p\u003e\n\u003cp\u003eThe A4J6 is suited for use in commercial and light industrial electrical systems where Class J fuse holders are installed. Its fast-acting characteristic makes it appropriate for protecting resistive loads, control circuits, and equipment that does not require time-delay fusing to accommodate inrush current. The cylindrical form factor and 20.6 mm diameter fit standard Class J fuse clips and holders commonly found in disconnect switches, control panels, and branch circuit protection assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003e6 amp continuous current rating for low-current circuit protection\u003c\/li\u003e\n \u003cli\u003e200 kA interrupting capacity at AC for high fault-current environments\u003c\/li\u003e\n \u003cli\u003e100 kA interrupting capacity at DC\u003c\/li\u003e\n \u003cli\u003eFast-acting response helps protect sensitive downstream components\u003c\/li\u003e\n \u003cli\u003eCylindrical body constructed with fiberglass, GMG, and polyester materials\u003c\/li\u003e\n \u003cli\u003eClass J form factor fits standard Class J fuse clips and holders\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 requiring a 6 amp fast-acting fuse with a 20.6 mm diameter body.\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. Always de-energize and lockout\/tagout the circuit before removing or installing fuses. Verify the fuse holder is rated for Class J fuses and confirm the voltage and current ratings of the circuit match the fuse specifications before energizing. Do not replace a fast-acting fuse with a time-delay fuse without confirming compatibility with the load type and overcurrent protection design.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 6 amps\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: J\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Fast-Acting\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity (AC)\u003c\/strong\u003e: 200 kA\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity (DC)\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\u003eBody Shape\u003c\/strong\u003e: Cylindrical\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: A4J6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERRAZ SHAWMUT","offers":[{"title":"Default Title","offer_id":68299635458354,"sku":"A4J6","price":34.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/907205e3b31d12f9461c04918e63066f.jpg?v=1793715188","url":"https:\/\/voomisupply.com\/products\/ferraz-shawmut-a4j6-class-j-fast-acting-fuse-6-amp","provider":"Voomi Supply","version":"1.0","type":"link"}
