Rated at 3000 amps, this heavy-duty fuse is perfect for service entrance equipment, feeder circuits, and large circuit breakers. Its clever time-delay design allows harmless surges—like motor starts or short spikes—to pass without tripping, but reacts immediately when a real fault occurs. That means your equipment stays safe, and you avoid costly downtime.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward thanks to silver-plated copper blade terminals, and the tough glass melamine (GMG) body keeps its shape even under continuous heavy loads. With a 200kA AC interrupting rating, the A4BY3000 handles the most demanding industrial and commercial conditions with confidence. Easy-to-read markings make maintenance simple, so you can quickly identify and replace the fuse without any guesswork.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHandles harmless surges without tripping thanks to time-delay design\u003c\/li\u003e\n\u003cli\u003e3000A rating for high-current circuits and service entrances\u003c\/li\u003e\n\u003cli\u003eRated for 600VAC \/ 300VDC applications\u003c\/li\u003e\n\u003cli\u003e200kA AC interrupting capacity protects against serious faults\u003c\/li\u003e\n\u003cli\u003eSilver-plated copper blade terminals for secure, reliable connections\u003c\/li\u003e\n\u003cli\u003eDurable GMG (glass melamine) body holds up under heavy use\u003c\/li\u003e\n\u003cli\u003eContinuous-duty at full ampere rating\u003c\/li\u003e\n\u003cli\u003eClear markings make maintenance quick and easy\u003c\/li\u003e\n\u003cli\u003eBolt-mounted installation ensures a stable fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e A4BY3000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e A4BY – Class L – Time-Delay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e Class L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmpere Rating:\u003c\/strong\u003e 3000A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 600VAC \/ 300VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency:\u003c\/strong\u003e 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeed\/Characteristic:\u003c\/strong\u003e Time-Delay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Bolted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type:\u003c\/strong\u003e Blade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Material:\u003c\/strong\u003e Silver-Plated Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Max Interrupting Rating:\u003c\/strong\u003e 200kA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e GMG (Glass Melamine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 127 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 273 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Weight:\u003c\/strong\u003e 8.7543 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial Compliance and Certifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRoHS Compliant\u003c\/li\u003e\n\u003cli\u003eUL\/CSA approved for low-voltage applications\u003c\/li\u003e\n\u003cli\u003eMeets industrial and commercial electrical protection standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe A4BY3000 shines in environments that demand high-current protection and reliable surge tolerance:\u003c\/li\u003e\n\u003cli\u003eService entrance panels\u003c\/li\u003e\n\u003cli\u003eFeeder circuits and distribution systems\u003c\/li\u003e\n\u003cli\u003eIndustrial machinery protection\u003c\/li\u003e\n\u003cli\u003eCommercial power systems\u003c\/li\u003e\n\u003cli\u003eCritical circuit breakers in essential infrastructure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\n\u003cdiv\u003e\n\u003cblockquote\u003e\n\u003cp style=\"font-size: 12px;\"\u003e\u003cem\u003eUse of Original Equipment Manufacturer (OEM) trademarks, names, and logos is for informational and identification purposes only.
