With a 2000A rating, this fuse is engineered to handle heavy-duty service entrance equipment, feeder circuits, and circuit breakers. Its time-delay design allows it to ride through harmless surges, like motor startups or brief spikes, without tripping unnecessarily, while still acting fast when a true fault occurs. That means your equipment stays safe, and your operations keep running smoothly. Designed with silver-plated copper blade terminals and a durable glass melamine (GMG) body, the A4BY2000 ensures reliable connections and long-lasting performance. High interrupting capacity of 200kA AC gives you the confidence that even the toughest electrical faults are managed safely and efficiently.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTime-delay design passes harmless surges without tripping\u003c\/li\u003e\n\u003cli\u003e2000A rating for high-current service entrance and feeder circuits\u003c\/li\u003e\n\u003cli\u003eRated for 600VAC \/ 300VDC applications\u003c\/li\u003e\n\u003cli\u003e200kA AC interrupting capacity for fast fault clearing\u003c\/li\u003e\n\u003cli\u003eSilver-plated copper blade terminals provide secure, reliable connections\u003c\/li\u003e\n\u003cli\u003eDurable GMG (glass melamine) body maintains stability under load\u003c\/li\u003e\n\u003cli\u003eContinuous-duty operation at full ampere rating\u003c\/li\u003e\n\u003cli\u003eClear markings simplify identification and replacement\u003c\/li\u003e\n\u003cli\u003eBolt-mounted installation for secure connections\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 A4BY2000\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 2000A\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\u003eProduct Diameter:\u003c\/strong\u003e 88.9 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Length:\u003c\/strong\u003e 273 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Weight:\u003c\/strong\u003e 3.8374 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\u003eDesigned for low-voltage UL\/CSA applications\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\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\u003eCircuit breakers in critical electrical 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.
