Overview

The Mersen A70P90-4 Amp-Trap® Form 101 high-speed fuse is a bolted blade fuse designed for critical protection in high-voltage AC and DC applications. Rated at 700VAC and 650VDC with a 90A current rating, this fuse delivers ultra-fast response times to minimize damage during short circuits. Its low I²t characteristic ensures superior component protection in drives, UPS systems, reduced voltage motor starters, and inverters. The A70P90-4 offers a 100kA interrupting rating for both AC and DC, making it ideal for demanding industrial environments. Typical applications include DC drives up to 650VDC, AC drives up to 700VAC, and critical power conversion systems where fast-acting protection is essential. The A70P series is widely used for replacement in existing systems due to its proven performance and broad compatibility. Available with indicator options (TI/TA) for visual status confirmation, this fuse combines reliability and precision. Designed for high-speed operation, it provides controlled arc voltage to reduce stress on circuit components during fuse clearing. The bolted blade mounting type ensures secure installation in industrial equipment.
