Why Choose the Mersen FR14GG50V25P Cylindrical Fuse-Link?
The Mersen FR14GG50V25P is a high-performance gG cylindrical fuse-link with striker, designed to provide full-range protection against overload and short-circuit currents in industrial electrical distribution systems. Part of the established Mersen FR14GG series, it combines dependable current-limiting performance with a durable 14 × 51 mm ceramic body.
Its gG operating characteristic enables the FR14GG50V25P to protect cables, conductors, motors and low-voltage networks across the complete overcurrent range. During an electrical fault, the fuse-link rapidly limits and interrupts excessive current, helping reduce thermal and mechanical stress on downstream equipment.
Rated at 25 A and 500 V AC, the FR14GG50V25P provides a high 120 kA AC breaking capacity. Its integrated striker can operate an auxiliary contact in a compatible fuse holder, allowing remote fault indication, alarm signalling or coordinated switching within industrial control systems.
Key Advantages
- Full-range gG protection against overloads and short circuits.
- 25 A rated current for industrial distribution applications.
- 500 V AC IEC rating for low-voltage electrical systems.
- 120 kA AC breaking capacity for dependable fault interruption.
- Integrated striker mechanism supports remote fuse-status indication.
- Compact 14 × 51 mm construction saves panel space.

Reliable Full-Range Circuit Protection
The Mersen FR14GG50V25P protects electrical installations by disconnecting unacceptable overload and short-circuit currents. Its gG classification provides protection throughout the complete operating range, making it suitable for general industrial distribution and equipment protection.
The fuse-link's current-limiting action reduces the peak current and energy passed to downstream components during a fault. When the fuse operates, its striker can activate an auxiliary contact in a compatible holder, supporting remote alarms, equipment shutdown or maintenance indication.
Typical Applications
- Industrial electrical distribution systems.
- Cable and conductor protection.
- Low-voltage power networks.
- Automation and control panels.
- Industrial machinery and OEM equipment.
- Switchboards and distribution assemblies.
