Mersen M300069 - PC32UD69V630TF Fuses (3 Pieces)

The Mersen Protistor® PC32UD69V630TF (Item M302162) is an ultra-fast acting high-speed square body fuse-link engineered for the demanding protection of power semiconductor devices. This Size 32 aR class fuse is optimized to provide superior short-circuit protection for diodes, thyristors, and IGBT modules in high-power applications such as industrial drives, large-scale power converters, and UPS systems.

Designed with a premium ceramic body and silver-plated contact surfaces, the fuse features internal elements embedded in high-grade solidified sand to ensure stable arcing control and extremely low I²t energy let-through. This model provides a high breaking capacity of 200kA, effectively safeguarding critical electronic components from thermal and magnetic stress during fault conditions. It is equipped with a mechanical striker for visual indication and the option to trigger a remote microswitch. The TTF flush-end M10 metric threaded design ensures a compact, low-resistance bolted connection.
