The Mersen TRS1.4R is a high-speed, current-limiting fuse designed for the protection of power semiconductors, such as diodes, thyristors, and IGBTs, in industrial power conversion equipment. It is rated for 1.4 amps and a maximum voltage of 500 VAC/VDC, providing precise overcurrent protection with a low I²t value to minimize thermal stress on sensitive components. The fuse features a compact, ferrule-style construction with a 10x38mm body, silver-plated contacts for reliable conductivity, and a ceramic body for high interrupting capacity. It complies with IEC 60269-4 and UL 248-13 standards for semiconductor fuse applications. Typical applications include variable frequency drives, UPS systems, DC power supplies, and motor control centers.
