Mersen PC73UD90V13CTF / V300516 Protistor Size 73 aR High-Speed Fuse, 1300A, 900VAC

The Mersen PC73UD90V13CTF (Reference Number: V300516) is an industrial-grade Protistor® ultra-fast acting square body fuse-link, specifically engineered for the high-capacity protection of semiconductor devices. This Size 73 aR-class fuse is designed to isolate faults in power converters, rectifiers, and large industrial drives precisely and rapidly. Rated for a nominal current of 1300A and a voltage of 900VAC (IEC), it features a low I²t let-through characteristic that minimizes thermal stress on power electronics during short-circuit events. The TTF (Tapped Terminal Face) design utilizes M12 threaded holes for a direct-to-busbar mounting configuration, ensuring a compact footprint and reliable electrical contact in heavy-duty power cabinets.
