Overview

The Mersen Amp-Trap® Form 101 high-speed fuse, SKU S084357, is engineered for the specific protection of diodes and other semiconductor devices. This fast-acting (FA) fuse features a compact 6.3x32mm cylindrical body, ideal for applications with space limitations. It is rated for 400V AC/DC operation and offers a high breaking capacity of 100kA AC and 50kA DC, providing robust current limitation. The fuse's low I²t minimizes damage to protected components during short circuits, and its controlled arc voltage reduces stress during fuse clearing. Indicator options are available for visual confirmation. This fuse is designed for applications such as the protection of heavy-duty devices like electrochemical rectifiers, IGBT modules, inverters, and converters. Its clip mounting design simplifies installation in industrial control panels, power supplies, and motor drives. Mersen products are designed for specific applications and operated under particular specifications and conditions.
