The Mersen A13X2000-128TA is a high-speed, current-limiting semiconductor protection fuse from the Amp-Trap Form 101 A13X series, rated at 2000A in a hockey-puck (Type 128TA) form factor with an integrated trigger actuator (TA) for external trip circuit interfacing. 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 (640,000 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 integrated trigger actuator provides a mechanical actuation signal to drive external disconnect mechanisms while 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 critical power conversion systems where coordinated shutdown via auxiliary trip circuitry is essential.
