£155.95
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.
Unlike aR semiconductor fuses that provide short-circuit protection only, the gR operating class provides both overload and short-circuit protection, helping simplify equipment protection while maintaining excellent current-limiting performance for sensitive semiconductor devices.
