Mersen PC32UD69V700A Protistor Fuse, 700A 690V AC, Size 32 aR, High-Speed Square Body with Striker - Pack of 3

The Mersen Protistor® PC32UD69V700A (Item Number V130114) is a high-capacity, ultra-fast acting square body fuse-link engineered for the advanced protection of power semiconductor devices. This Size 32 aR class fuse is designed for 690V AC applications, making it an essential component for high-power industrial equipment such as large rectifiers, traction inverters, and heavy-duty motor drives. It provides exceptional current-limiting performance with extremely low I²t levels to prevent catastrophic failure of sensitive semiconductor components like IGBTs and diodes during fault conditions.

Built with a premium ceramic body for superior arc containment and thermal management, the fuse utilizes silver-plated copper contact surfaces to minimize power loss and heat generation. The internal silver elements and high-purity silica sand filler support a high breaking capacity of 200kA. This unit features an integrated mechanical striker that serves as a reliable trip indicator and can be used to engage auxiliary microswitches for remote status signaling and automated system shutdowns.
