Overview

The Mersen A100P100-4TA is a high-speed Amp-Trap® Form 101 fuse designed for critical protection in high-voltage systems. Rated for 1000VAC and 750VDC, this 100A fuse delivers fast-acting current limiting with a 100kA interrupting rating and 25ms let-through time. Its low I²t minimizes damage to protected components during short circuits, while controlled arc voltage reduces stress on circuit elements. The bolted blade mounting ensures secure installation, and the TA (Trigger Actuator) indicator provides clear visual confirmation of blown fuse status. This fuse is optimized for demanding applications including UPS systems, AC/DC drives, reduced voltage motor starters, and semiconductor protection in 1000V or less systems. Part of Mersen’s A100P series, it offers reliable performance across ampere ratings from 15 to 1000A, ensuring broad compatibility for high-voltage industrial and commercial installations.
