Why Choose the Mersen FR22GR69V100 Protistor® Semiconductor Fuse?
The Mersen FR22GR69V100, item number F1018560, is a high-speed Protistor® cylindrical semiconductor fuse designed to protect sensitive power semiconductor devices against overload and short-circuit faults. Part of Mersen's 22 × 58 mm gR series, it is suitable for demanding industrial power-electronic systems operating at up to 690 V AC according to IEC.
With a 100 A current rating, gR full-range operating characteristic and an exceptionally high 160 kA AC breaking capacity, the FR22GR69V100 provides fast, current-limiting protection for IGBTs, thyristors, diodes, rectifiers and other semiconductor components used in drives, converters, UPS systems and industrial power supplies.
Its durable ceramic body, silver-plated copper ferrules and low let-through energy help reduce thermal and mechanical stress on expensive semiconductor devices. The compact cylindrical format also allows straightforward installation in compatible 22 × 58 mm fuse clips and Mersen fuse holders.

Fast Full-Range Protection for Power Electronics
The Mersen FR22GR69V100 is engineered to interrupt high fault currents rapidly, limiting the electrical energy passed to connected semiconductor components. This fast current-limiting action helps reduce the risk of catastrophic device failure and can minimise collateral damage within power-electronic assemblies.
Its gR operating class provides full-range protection against both overload and short-circuit currents. This makes the fuse suitable for applications where comprehensive protection of power semiconductors is required without relying exclusively on separate overload protection.

- Industrial motor drives.
- Power converters.
- UPS systems.
- Industrial inverters.
- Rectifier assemblies.
- Battery energy storage systems.
