Information About A4BY800


The A4BY800 is an 800 Amp fuse manufactured by Mersen, designed to provide robust overcurrent protection in electrical systems. As part of Mersen's A4BY series, it is specifically engineered for current limiting applications in low voltage circuits. 

This fuse is non-indicating, meaning it does not feature a visual indicator to show whether it has operated. It is designed with rejection characteristics, ensuring compatibility only with specific fuse holders to prevent mismatching. 

Rated for 800 Amperes of current and compatible with voltages up to 600 VAC and 300 VDC, the A4BY800 fuse can handle substantial electrical loads without compromising safety or performance. It offers a high interrupt rating of 200,000 Amperes at 600 VAC and 100,000 Amperes at 300 VDC, ensuring reliable operation even under fault conditions.
