Mersen PC32UD60V1100A Protistor Fuse, 1100A 600V AC, Size 32 aR, High-Speed Square Body with Striker - Pack of 3

The Mersen Protistor® PC32UD60V1100A (Item Number D130122) is an ultra-fast acting square body fuse-link designed specifically for the protection of high-power semiconductor devices. Rated at 1100A and 600V AC, this Size 32 aR category fuse is a critical safety component for industrial power systems, including large-scale rectifiers, variable speed drives, and static switches. It is engineered to provide extremely low let-through energy (I²t), offering premium protection for sensitive electronic components such as thyristors and IGBTs against high-magnitude fault currents.

The fuse construction utilizes a high-strength ceramic body and pure silver elements embedded in high-purity silica sand, ensuring stable performance and effective arc quenching. The contact surfaces are silver-plated to maintain low contact resistance and minimize power loss. This model features an integrated mechanical striker, providing both local visual indication of a blown fuse and the ability to trigger a microswitch for remote fault detection and system shutdown protocols.
