The Mersen A13X1500-128 is a high-speed, current-limiting semiconductor protection fuse from the Amp-Trap Form 101 A13X series, rated at 1500A in a hockey-puck (Type 128) form factor. Engineered specifically for the protection of high-power diodes, thyristors, and power semiconductor devices in large-scale rectifier circuits, this compact disc-type fuse delivers exceptional I²t performance (360,000 A²s melting) to minimize thermal stress during fault conditions. With dual AC/DC voltage ratings (130VAC/100VDC) and interrupting capacities of 8kA/10kA respectively, the hockey-puck design with 3/8-24 threaded terminals enables direct mounting to bus bars and heat sinks, making it the preferred choice for high-current industrial power conversion systems, electroplating rectifiers, and large DC drives.
