Built for demanding commercial and industrial applications, this 800A fuse helps protect mains, feeders, and power distribution circuits from overloads and short circuits while still allowing the temporary startup surge common with large motors and heavy equipment. That time-delay feature helps your equipment start smoothly without nuisance fuse operation, which is especially important in high-load environments.\u003c\/p\u003e\n\u003cp\u003eThis Amp-Trap® Class L fuse also delivers strong fault protection with a 200 kA interrupting rating, helping you reduce the impact of severe electrical faults before damage spreads through the system. Its silver-plated copper blade terminals support efficient conductivity and reliable connections, and the bolted mounting style keeps the fuse securely in place in switchgear and other distribution equipment. Rated for both AC and DC systems, the A4BT800 is a dependable choice for facilities that need consistent circuit protection day after day.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e800A Class L time-delay fuse for industrial and commercial applications\u003c\/li\u003e\n\u003cli\u003eHelps protect electrical systems from overloads and short circuits\u003c\/li\u003e\n\u003cli\u003eTime-delay performance allows temporary motor startup surges without unnecessary opening\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting design helps reduce damage during fault conditions\u003c\/li\u003e\n\u003cli\u003eRated for 600VAC and 500VDC systems\u003c\/li\u003e\n\u003cli\u003e200 kA interrupting rating for high fault-current protection\u003c\/li\u003e\n\u003cli\u003eSilver-plated copper blade terminals for dependable conductivity\u003c\/li\u003e\n\u003cli\u003eBolted mounting design for secure installation\u003c\/li\u003e\n\u003cli\u003eSupports 100% rated loading under normal operating conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Mersen\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e A4BT800\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e A4BT Amp-Trap®\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Class L Time-Delay Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmpere Rating:\u003c\/strong\u003e 800A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Voltage AC:\u003c\/strong\u003e 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Voltage DC:\u003c\/strong\u003e 500VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency:\u003c\/strong\u003e 50\/60 Hz\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e Class L\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharacteristic:\u003c\/strong\u003e Time Delay\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 200 kA AC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Bolted\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Type:\u003c\/strong\u003e Blade\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Material:\u003c\/strong\u003e Silver-Plated Copper\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e GMG\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Diameter:\u003c\/strong\u003e 76.2 mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Length:\u003c\/strong\u003e 219.2 mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Weight:\u003c\/strong\u003e 1.6919 kg\u003cbr\u003e\n\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 UL and CSA low-voltage fuse applications\u003c\/li\u003e\n\u003cli\u003eSuitable for AC and DC circuit protection systems\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe A4BT800 is commonly used in switchgear, motor control centers, HVAC equipment, industrial machinery, feeders, and large commercial power distribution systems.
