Why Choose the Mersen FR22GG50V80P Cylindrical Fuse Link?
The Mersen FR22GG50V80P is a high-performance 22 × 58 mm cylindrical gG fuse link designed to protect cables, electrical equipment and low-voltage distribution networks against overloads and short-circuit currents. Rated at 80 A and 500 V AC, it provides dependable full-range protection for industrial and commercial electrical installations.
As part of the Mersen ferrule fuse-link range, this fuse uses a gG operating characteristic to interrupt both sustained overload currents and severe short-circuit faults. Its current-limiting performance helps reduce the thermal and mechanical stress placed on conductors, switchgear and connected equipment during an electrical fault.
The FR22GG50V80P features a robust ceramic body, silver-plated copper ferrule contacts and an integrated striker indication system. The striker can activate a compatible auxiliary contact or signalling accessory when the fuse operates, helping engineers identify faults quickly and minimise maintenance downtime.

Reliable Protection for Electrical Distribution Circuits
A gG fuse link provides full-range protection by responding to both overload currents and high-level short circuits. This makes the Mersen FR22GG50V80P suitable for protecting cables, distribution circuits, motors and low-voltage electrical networks without requiring a separate fuse for overload protection.
During a severe fault, the fuse rapidly limits and interrupts the current before it can cause excessive thermal or mechanical damage. Its high breaking capacity makes it suitable for installations where substantial prospective fault currents may be present.
Typical Applications
- Industrial electrical distribution panels.
- Low-voltage switchgear and control panels.
- Cable and conductor protection.
- Motor and machinery supply circuits.
- Commercial and industrial power networks.
- Modular cylindrical fuse holders and disconnectors.
