Why Choose the Mersen FR22GG69V20 Cylindrical Fuse-Link?
The Mersen FR22GG69V20 is a high-performance 22 × 58 mm gG cylindrical fuse-link designed to provide full-range protection for cables, conductors, motors and low-voltage electrical networks. Its gG operating characteristic protects against both sustained overloads and severe short-circuit currents, making it suitable for general-purpose industrial circuit protection.
As part of the established Mersen FR22 gG ferrule fuse-link range, the FR22GG69V20 combines strong current-limiting performance with a durable ceramic body and silver-plated contacts. During an electrical fault, it rapidly limits and interrupts excessive current, helping reduce thermal and mechanical stress on cables, switchgear and connected equipment.
With a rated current of 20 A, an IEC rated voltage of 690 V AC and a standard 22 × 58 mm cylindrical format, the FR22GG69V20 is suitable for industrial distribution panels, machinery, control systems and OEM equipment. Its non-striker design is intended for applications where remote fuse-operation indication is not required.
Key Advantages
- Full-range gG protection against overloads and short circuits.
- 20 A rated current for industrial distribution applications.

Reliable Full-Range Electrical Circuit Protection
The Mersen FR22GG69V20 provides full-range protection by responding to sustained overload conditions and high short-circuit currents. Its current-limiting operation reduces the energy allowed to pass through the circuit during a fault, helping protect cables, switchgear and electrical equipment from excessive damage.
Unlike an aM motor fuse-link, a gG fuse provides protection across its complete operating range. This makes the FR22GG69V20 suitable for general electrical distribution, cable protection, machinery circuits 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 manufacturing equipment.
