Mersen PC32UD69V800A Protistor Fuse, 800A 690V AC, Size 32 aR, High-Speed Square Body with Striker - Pack of 3

The Mersen Protistor® PC32UD69V800A (Item Number W130115) is a high-performance, ultra-fast acting square body fuse-link designed for the protection of power semiconductor devices. This Size 32 aR category fuse is rated for 690V AC and is engineered to provide superior protection for high-power electronics, including rectifiers, inverters, and power converters. It is specifically designed to minimize let-through energy (I²t), ensuring the safety of sensitive components such as SCRs and diodes during overcurrent or short-circuit events.

The fuse is constructed with a high-strength ceramic body and silver-plated contact surfaces, ensuring high thermal stability and low power dissipation. Its internal system, featuring pure silver elements and high-purity silica sand, enables a massive breaking capacity of 200kA. This model includes a built-in mechanical striker, which provides a visual indication of operation and can be paired with microswitches for remote monitoring of the circuit status.
