The Mersen A13X800-4 Amp-trap Form 101 fuse is a robust, high-current protection solution designed specifically for safeguarding large-scale semiconductor equipment in industrial power systems. With an 800A rating and a 130V AC/100V DC voltage window, this fast-acting, current-limiting fuse is the definitive choice for protecting rectifiers, inverters, and high-power DC drives from catastrophic short-circuit damage.
Engineered with a substantial 100,000 A²s melting I²t and a high 8kA/10kA interrupting capacity, the A13X800-4 minimizes fault energy let-through to preserve the lifespan of critical power semiconductors. This bolt-in Type 4 fuse provides procurement engineers with a reliable, high-performance link for demanding applications where system uptime and safety are non-negotiable.
