Overview

Mersen SKU P093324 is a miniature 5x20mm high-speed fuse designed for fast-acting overcurrent protection in sensitive electronic circuits. Rated at 400V AC and 2A, this fuse provides rapid response to overcurrent and short-circuit events, minimizing damage to connected semiconductor devices and electronic components. Its very fast-acting (FA) characteristic ensures immediate interruption of fault currents, reducing I²t let-through and protecting downstream equipment. The clip mounting design enables straightforward installation in control panels, power supplies, and other compact electrical assemblies. Engineered for space-efficient integration, this fuse is ideal for applications requiring precise and immediate fault protection, such as power conversion systems, test equipment, and industrial control circuits. The 5x20mm form factor allows for dense circuit layouts while maintaining reliable protection. This fuse is part of Mersen's Amp-Trap® series, known for current-limiting performance and low let-through energy in high-speed protection scenarios.
