The Mersen A13X350-4TI is a high-speed, current-limiting semiconductor protection fuse from the Amp-Trap Form 101 A13X series, rated at 350A and featuring an integral blown-fuse trigger indicator (TI) for instant visual status monitoring. Designed for the protection of diodes, thyristors, and power semiconductor devices in rectifier circuits, this bolt-in Type 4 fuse delivers ultra-low I²t performance (20,000 A²s melting) to minimize thermal stress during fault events. With dual AC/DC voltage ratings (130VAC/100VDC) and interrupting capacities of 8kA/10kA respectively, the built-in trigger indicator provides a reliable remote signaling interface, making it ideal for mission-critical industrial drives, UPS systems, and DC power supplies where immediate fault detection is essential.
