Mersen A25X20-1 - Semiconductor Fuse 20A 300V (50kA AIC VFA)

Mersen A25X20-1 is a low voltage semiconductor protection fuse from the Amp-Trap family, engineered for very fast-acting circuit protection in power electronics. Rated for 300V AC/DC systems with a 20A current capacity, this ferrule-connected fuse features a compact 0.56" diameter design with a 50kA@300V interrupting rating for robust short-circuit protection. Its VFA (Very Fast Acting) characteristic provides precise overcurrent protection for sensitive semiconductor devices, constructed with durable materials meeting industrial standards. The fuse is specifically designed for protecting rectifiers, inverters, motor drives, and other power conversion equipment requiring Class semiconductor protection.
