Why Choose the Mersen FR22GG69V50 Cylindrical Fuse-Link?
The Mersen FR22GG69V50 is a high-performance 22 × 58 mm gG cylindrical fuse-link designed to provide full-range protection for cables, motors, low-voltage networks and industrial electrical equipment. Its gG operating characteristic protects against both overload and short-circuit currents, making it suitable for general-purpose circuit protection in demanding industrial installations.
As part of the established Mersen FR22 gG ferrule fuse-link range, the FR22GG69V50 combines strong current-limiting performance with a robust ceramic body and silver-plated copper contacts. During a fault, it rapidly limits and interrupts excessive current, helping reduce thermal and mechanical stress on conductors, switchgear and connected equipment.
With a rated current of 50 A, an IEC rated voltage of 690 V AC and a standard 22 × 58 mm cylindrical format, the FR22GG69V50 is suitable for industrial distribution panels, machinery, motor circuits and OEM electrical systems. Its non-striker design is ideal for applications where remote fuse-operation signalling is not required.
Key Advantages
- Full-range gG protection against overloads and short circuits.
- 50 A rated current for industrial distribution applications.

Reliable Full-Range Electrical Circuit Protection
The Mersen FR22GG69V50 protects electrical circuits by responding to sustained overload conditions and severe short-circuit currents. Its current-limiting operation reduces the amount of energy allowed to pass during a fault, helping protect cables, switchgear and electrical equipment from excessive thermal and mechanical damage.
Unlike an aM motor fuse-link, a gG fuse provides protection throughout its full operating range. This makes the FR22GG69V50 suitable for cable protection, industrial distribution circuits, machinery and correctly coordinated motor applications.
Typical Applications
- Industrial electrical distribution panels.
- Cable and conductor protection.
- Low-voltage electrical networks.
- Machinery and automation control panels.
- Motor and feeder circuits.
- OEM production and processing equipment.
