LITTELFUSE Semiconductor Fuse: PSR Series, Very-Fast-Acting, 125 A, 1,300 V AC

The LITTELFUSE PSR Series semiconductor fuse (MPN PSR070FS0125Z) provides very-fast-acting overcurrent protection for industrial power electronics, including drives, inverters, and UPS systems. Its high interrupting rating safeguards sensitive semiconductor components from short circuits and overloads in AC/DC circuits up to 1,300 V AC and 1,000 V DC.

The LITTELFUSE PSR070FS0125Z is a very-fast-acting threaded flush-end square fuse rated at 125 A, 1,300 V AC, and 1,000 V DC. It belongs to the PSR Series and is designed for AC/DC voltage applications. The fuse features a compact square body with threaded flush-end terminals for secure mounting in industrial equipment.
