Mersen PC32UD69V1000A Protistor Fuse, 1000A 690V AC, Size 32 aR, High-Speed Square Body with Striker - Pack of 3

The Mersen Protistor® PC32UD69V1000A (Item Number Y130117) is a high-performance, ultra-fast acting square body fuse-link designed for the comprehensive protection of power semiconductor devices. This Size 32 aR class fuse is rated for 690V AC and is purpose-built for high-power industrial applications, including large power rectifiers, AC/DC drives, and renewable energy inverters. It is engineered to provide an extremely fast response to overcurrents, ensuring the lowest possible let-through energy (I²t) to safeguard sensitive components like thyristors and high-power transistors.

The fuse is constructed using high-grade ceramic for superior thermal resistance and arc quenching. It features silver-plated contact surfaces for optimal conductivity and long-term durability in demanding industrial environments. With a massive breaking capacity of 200kA, it ensures safety even in the event of severe short circuits. This model is equipped with a mechanical striker, providing reliable visual trip indication and allowing for the integration of remote monitoring microswitches.
