Why Choose the Mersen R301315 High-Speed Semiconductor Fuse?
The Mersen R301315, catalogue reference PC71GB69V160TF, is a genuine Protistor® Size 71 high-speed semiconductor fuse engineered to provide full-range protection for sensitive power semiconductor equipment. Rated at 160A with a 690VAC IEC voltage rating, this gR characteristic fuse is designed to protect both against overloads and short-circuit faults in modern power conversion systems.
Manufactured using pure silver die-cut fuse elements embedded in solidified silica sand, the R301315 delivers low let-through energy (I²t), excellent current limiting and a high interrupting capacity. The fuse incorporates an integrated striker indicator and flush ends with metric threaded terminals, making it suitable for demanding industrial installations.
Protistor® gR fuses are specifically designed for semiconductor protection in applications such as variable speed drives, UPS systems, rectifiers, inverters and industrial power converters where maximum equipment reliability is essential.
