FDH US Type Fuses

This fuse series is mainly used in North American standard electrical equipment. Due to it’s excellent aR semiconductor characteristics, fast protection, small I²T value, low operating temperature, low power consumption, high breaking capacity, strong arc extinguishing capacity and other advantages, this fuse series is increasingly used in SVG, active filters, EV charging devices, and various power supply, and other fields. At the same time, due to good anti-vibration, flame retardant and other superior environmental tolerance, this fuse series is also suitable for rail transit, motor vehicles and other fields.

Rated voltage: 500Vac/dc
