The Mersen A13X1000-128 Amp-trap Form 101 fuse is a high-current, hockey-puck style semiconductor protection device engineered for the most demanding industrial power conversion applications. With a 1000A continuous current rating and a compact Type 128 flat-base mounting configuration, this fast-acting, current-limiting fuse provides critical defense for rectifiers, inverters, and large DC drives operating on 130V AC or 100V DC circuits.
Designed with an exceptionally low 160,000 A²s melting I²t and an 8kA/10kA interrupting capacity, the A13X1000-128 minimizes destructive fault energy to protect valuable power semiconductors, ensuring maximum system uptime and equipment longevity. Its hockey-puck form factor with 3/8-24 threaded terminals makes it ideal for high-power press-pack assemblies where reliable, low-inductance protection is essential.
