Rated at 1400 amps, this time-delay Class L fuse protects your service entrance panels, feeder circuits, and large breakers from overloads and short circuits—while letting normal startup surges pass through without tripping. Unlike standard fuses, the time-delay design gives motors, transformers, and other equipment a few extra seconds to start up, so you avoid unnecessary shutdowns. At the same time, it stays ready to interrupt serious faults, keeping your system safe under high-stress conditions. Installation is straightforward thanks to its bolted mounting and blade-style terminals made from silver-plated copper. The GMG insulated body provides long-lasting performance, even in demanding industrial environments.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-capacity protection:\u003c\/strong\u003e Rated for 1400A to keep circuits safe.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTime-delay design:\u003c\/strong\u003e Allows temporary surges without unnecessary trips.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC\/DC compatible:\u003c\/strong\u003e Works with 600VAC and 300VDC systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh fault handling:\u003c\/strong\u003e Interrupting rating of 200 kA.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable connections:\u003c\/strong\u003e Blade terminals with silver-plated copper.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt to last:\u003c\/strong\u003e GMG insulated body withstands heavy-duty use.\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\u003eFuse Class:\u003c\/strong\u003e Class L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmpere Rating:\u003c\/strong\u003e 1400A\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\u003eMounting:\u003c\/strong\u003e Bolted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Type:\u003c\/strong\u003e Blade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 200 kA AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 273 mm length × 76.2 mm diameter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Weight:\u003c\/strong\u003e 2.7 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\u003eUL listed for low-voltage applications\u003c\/li\u003e\n\u003cli\u003eSilver-plated copper terminals for reliable conductivity\u003c\/li\u003e\n\u003cli\u003eGMG insulating material for safe and consistent performance\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 A4BY1400 is perfect for industrial and commercial settings where heavy startup loads and high fault currents are common.
