Why Choose the Mersen FR22GR69V40 Protistor® High-Speed Fuse?
The Mersen FR22GR69V40, also identified by item number B1018556, is a high-performance Protistor® high-speed cylindrical semiconductor fuse designed to protect sensitive power electronic components in demanding industrial systems. Its ultra-fast current-limiting action helps reduce the damaging thermal and electrical energy reaching semiconductors during overload and short-circuit conditions.
As part of the trusted Mersen Protistor® 22 × 58 mm gR range, the FR22GR69V40 provides full-range semiconductor protection in a compact cylindrical format. It is suitable for safeguarding IGBTs, thyristors, power diodes, rectifiers and other semiconductor devices used in drives, converters, inverters and industrial power supplies.
With a rated current of 40 A, a rated voltage of 690 V AC according to IEC standards and a maximum breaking capacity of 160 kA, this fuse delivers dependable fault interruption for critical power electronic equipment. The non-striker design is ideal for installations where remote or mechanical fuse-operation indication is not required.

Full-Range Protection for Power Semiconductors
The Mersen FR22GR69V40 uses an ultra-fast gR operating characteristic to protect semiconductor devices against both overload and short-circuit currents. Its rapid response and low I²t values help limit the energy passing through the circuit, reducing the risk of costly damage to sensitive electronic components.
Unlike partial-range aR fuses, a gR fuse provides full-range protection. This makes the FR22GR69V40 particularly suitable for applications where a single fuse is required to respond to a broad range of overcurrent conditions while maintaining the fast operating performance needed by power semiconductors.
Typical Applications
- Variable frequency drives.
- Industrial motor drives and soft starters.
- Power converters and rectifier systems.
- Inverters and switching power supplies.
- Uninterruptible power supply systems.
- Renewable energy conversion equipment.
- Industrial automation and control panels.
