Mersen PC32UD69V315TF Protistor Fuse, 315A 690V AC, Size 32 aR, High-Speed Square Body with Striker - Pack of 3

The Mersen Protistor® PC32UD69V315TF (Item M302162) is a professional-grade, ultra-fast acting square body fuse designed for the high-performance protection of power semiconductor devices. This Size 32 fuse is specifically engineered to provide state-of-the-art protection for diodes, thyristors, and IGBT modules in modern power conversion equipment, including inverters, motor drives, and UPS systems.

Featuring a robust ceramic body and silver-plated brass contact surfaces, the fuse utilizes die-cut elements embedded in solidified sand to ensure precise arcing control, exceptionally low I²t clearing values, and a high breaking capacity of 200kA. This model includes an integrated mechanical striker for visual trip indication or for operation of a field-mountable microswitch. The TTF flush-end M10 metric thread design ensures a secure, low-resistance bolted connection.
