Why Choose the Mersen FR14GG69V40 Cylindrical Fuse-Link?
The Mersen FR14GG69V40 is a high-performance 14 × 51 mm gG cylindrical fuse-link designed to protect cables, conductors, motors and low-voltage electrical networks against overload and short-circuit currents. Its full-range gG operating characteristic makes it suitable for general-purpose protection across a wide variety of industrial electrical distribution applications.
Part of the established Mersen FR14 gG ferrule fuse-link range, the FR14GG69V40 combines effective current limitation with a durable ceramic body and silver-plated contacts. During a fault, it rapidly interrupts excessive current to help reduce thermal and mechanical stress on cables, switchgear and connected equipment.
With a rated current of 40 A, a rated voltage of 690 V AC and a standard 14 × 51 mm cylindrical format, the FR14GG69V40 is suitable for industrial control panels, distribution boards, machinery and OEM electrical systems. Its compact dimensions enable dependable circuit protection where panel space is limited.

Reliable Protection for Electrical Distribution Systems
The Mersen FR14GG69V40 provides full-range protection by responding to sustained overloads as well as high short-circuit currents. Its current-limiting performance helps prevent excessive fault energy from reaching cables, switchgear and connected electrical equipment.
Unlike an aM motor fuse, a gG fuse-link provides both overload and short-circuit protection within its rated operating range. This makes the FR14GG69V40 suitable for general industrial distribution circuits, cable protection, machinery and correctly coordinated motor applications.
Typical Applications
- Industrial electrical distribution panels.
- Cable and conductor protection.
- Machinery control panels.
- Low-voltage electrical networks.
- Motor and feeder circuits.
- OEM manufacturing and automation equipment.
