Why Choose the Mersen FR22GG50V125P Cylindrical Fuse Link?
The Mersen FR22GG50V125P is a high-performance 22 × 58 mm gG cylindrical fuse link designed to provide reliable protection for cables, electrical distribution circuits and industrial low-voltage equipment. Rated at 125 A and 500 V AC, it offers full-range protection against both overload currents and short-circuit faults.
As a gG general-purpose fuse link, the FR22GG50V125P can interrupt fault currents across its complete operating range. This makes it suitable for protecting conductors, distribution equipment, control panels and other industrial loads without requiring a separate short-circuit protection device.
The fuse incorporates an integrated striker mechanism, which can provide clear fuse operation indication or activate an auxiliary contact when installed in a compatible fuse holder. Its robust ceramic body and silver-plated contacts support dependable operation in demanding industrial installations.

Reliable Protection for Electrical Distribution Circuits
The Mersen FR22GG50V125P uses a gG operating characteristic to protect cables and electrical equipment against sustained overloads and severe short-circuit currents. During a fault, the fuse rapidly limits and interrupts the current, reducing the thermal and mechanical stress placed on conductors and connected equipment.
Unlike partial-range motor fuses, a gG fuse provides protection throughout its complete current range. This makes the FR22GG50V125P a practical solution for industrial distribution boards, switchgear assemblies and circuits where comprehensive conductor protection is required.
Typical Applications
- Industrial electrical distribution systems.
- Low-voltage switchboards and control panels.
- Cable and conductor protection.
- Industrial machinery and production equipment.
- Power distribution circuits.
- Commercial electrical installations.
- OEM panels and automation systems.
