Frequently Asked Questions
What is the LITTELFUSE PSR071FL0450Z semiconductor fuse used for?
The LITTELFUSE PSR071FL0450Z is a very-fast-acting threaded flush-end square fuse used for overcurrent protection in industrial power electronics, including drives, inverters, and UPS systems. It protects sensitive semiconductor devices from short circuits and overloads in AC/DC circuits up to 1,300 V AC and 1,000 V DC.
What are the specifications of the LITTELFUSE PSR071FL0450Z?
The LITTELFUSE PSR071FL0450Z is a PSR Series semiconductor fuse rated at 450 A, 1,300 V AC, and 1,000 V DC. It is a very-fast-acting threaded flush-end square fuse with AC/DC voltage type. The manufacturer part number is PSR071FL0450Z, and it is designed for industrial overcurrent protection.
Where to buy the LITTELFUSE PSR071FL0450Z worldwide?
You can source the LITTELFUSE PSR071FL0450Z through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply this fuse to industrial customers globally.
How to select the correct LITTELFUSE PSR series fuse for an application?
To select the correct LITTELFUSE PSR series fuse, match the voltage rating (AC/DC), current rating (e.g., 450 A), and interrupting capacity to your circuit requirements. Ensure the very-fast-acting characteristic suits semiconductor protection. Verify physical dimensions and mounting style (threaded flush-end square) fit your equipment. Consult the fuse datasheet for time-current curves.
