Product Description

The LITTELFUSE PSR Series Semiconductor Fuse is a very-fast-acting threaded flush-end square fuse rated at 50 A, 700 V AC, and 600 V DC. This AC/DC voltage type fuse (MPN PSR030FS0050Z) is designed for overcurrent protection in industrial equipment.

Frequently Asked Questions

What is the LITTELFUSE PSR Series semiconductor fuse used for?

The LITTELFUSE PSR Series semiconductor fuse (MPN PSR030FS0050Z) provides very-fast-acting overcurrent protection for power electronics, drives, and industrial equipment. Its 50 A rating and 700 V AC / 600 V DC capability make it suitable for protecting sensitive semiconductor circuits from short circuits and overloads.

What are the specifications of the LITTELFUSE PSR030FS0050Z fuse?

The LITTELFUSE PSR030FS0050Z is a very-fast-acting threaded flush-end square fuse rated at 50 A, 700 V AC, and 600 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.

Where to buy the LITTELFUSE PSR030FS0050Z fuse worldwide?
