Frequently Asked Questions

What is the LITTELFUSE PSR Series semiconductor fuse used for?

The LITTELFUSE PSR Series very-fast-acting fuse protects power semiconductors such as diodes, thyristors, and IGBTs from overcurrents. It is commonly applied in variable-speed drives, UPS systems, and power conversion equipment where fast fault clearing is critical to prevent component damage.

What are the specifications of the LITTELFUSE PSR030FS0315Z fuse?

The LITTELFUSE PSR030FS0315Z is a very-fast-acting threaded flush-end square fuse rated at 315 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.

Where to buy the LITTELFUSE PSR030FS0315Z fuse worldwide?

3G Electric supplies the LITTELFUSE PSR030FS0315Z fuse to customers worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact our team for a quote and lead time on this very-fast-acting semiconductor fuse.

How to select the correct LITTELFUSE PSR series fuse for an application?

Select the PSR fuse based on the continuous load current (typically 125% of rated current), available fault current, and system voltage (AC or DC). Ensure the fuse's interrupting rating exceeds the maximum fault current. For semiconductor protection, choose a very-fast-acting characteristic to minimize I²t let-through energy.
