Why Choose the Mersen FR14GG50V40P Cylindrical Fuse-Link?
The Mersen FR14GG50V40P is a dependable 14 × 51 mm gG cylindrical fuse-link with striker, designed to protect cables, conductors, low-voltage networks and industrial electrical equipment against overload and short-circuit currents. Its full-range gG operating characteristic makes it suitable for general-purpose circuit protection across industrial distribution and control applications.
As part of the established Mersen FR14 gG ferrule fuse-link range, the FR14GG50V40P combines effective current limitation with a robust ceramic body and silver-plated contacts. During a fault, the fuse rapidly limits and interrupts excessive current, helping reduce the thermal and mechanical stresses imposed on switchgear, cables and connected equipment.
With a rated current of 40 A, an IEC rated voltage of 500 V AC and a standard 14 × 51 mm cylindrical format, the FR14GG50V40P is suitable for industrial control panels, distribution equipment, machinery and OEM systems. Its integrated striker can operate a compatible auxiliary contact for remote indication, electrical interlocking or equipment shutdown.

Reliable Full-Range Circuit Protection with Striker Indication
The Mersen FR14GG50V40P provides full-range protection by responding to sustained overloads and severe short-circuit currents. Its current-limiting performance reduces the energy allowed to pass through the circuit during a fault, helping protect cables, switchgear and connected equipment from excessive thermal and mechanical damage.
The integrated striker operates when the fuse-link ruptures and can activate an auxiliary contact in a compatible fuse holder. This functionality supports remote fault indication, electrical interlocking and automatic equipment shutdown in monitored industrial systems.
Typical Applications
- Industrial electrical distribution panels.
- Cable and conductor protection.
- Low-voltage electrical networks.
- Machinery and automation control panels.
- Motor and feeder circuits.
- Systems requiring remote fuse-status indication.
