Why Choose the Mersen FR10GG40V12P Cylindrical Fuse Link?
The Mersen FR10GG40V12P is a compact 10 × 38 mm cylindrical gG fuse link with integrated striker, designed to protect cables, electrical equipment and low-voltage distribution circuits against overloads and short-circuit currents. Rated at 12 A and 400 V AC, it provides reliable full-range circuit protection for industrial and commercial electrical installations.
As part of the Mersen FR10 ferrule fuse-link range, this fuse uses a gG operating characteristic to respond to both sustained overload conditions and severe short-circuit faults. Its current-limiting performance helps reduce thermal and mechanical stress on conductors, switchgear and connected equipment during an electrical fault.
The FR10GG40V12P features a robust ceramic body, cylindrical ferrule contacts and an integrated striker for fuse-operation indication. When used with a compatible fuse holder or signalling accessory, the striker can help maintenance teams identify an operated fuse quickly and minimise equipment 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-circuit faults. This makes the Mersen FR10GG40V12P suitable for protecting cables, conductors, switchgear and connected electrical equipment throughout its operating range.
During a severe fault, the fuse limits and interrupts the current before excessive thermal or mechanical damage can occur. Its high breaking capacity supports use in installations with substantial prospective fault currents, while the integrated striker allows fuse operation to be indicated through compatible accessories.
Typical Applications
- Industrial electrical distribution panels.
- Low-voltage switchgear and control panels.
- Cable and conductor protection.
- Machinery and equipment supply circuits.
- Commercial electrical installations.
- Compatible cylindrical fuse holders and disconnectors.
