The Mersen A13X350-4 Amp-trap Form 101 fuse is a high-performance, fast-acting semiconductor protection device engineered to safeguard sensitive power electronics in industrial and commercial applications. Rated for 350A with a compact Type 4 bolt-in form factor, this current-limiting fuse delivers a critical layer of defense for rectifiers, inverters, and DC drives operating on 130V AC or 100V DC circuits.
Designed with an exceptionally low I²t (20,000 A²s melting) to minimize let-through energy during fault conditions, this fuse ensures maximum equipment longevity and system uptime. With an 8kA AC/10kA DC interrupting rating and a proven track record in demanding environments, the A13X350-4 is an essential component for procurement engineers specifying robust circuit protection in drives, UPS systems, and power conversion equipment.
