Why Choose the Mersen FR22GG69V50P Cylindrical Fuse-Link?
The Mersen FR22GG69V50P is a high-performance gG cylindrical fuse-link with striker designed to provide full-range protection against overloads and short circuits in industrial electrical distribution systems. Part of the established Mersen FR22GG series, it combines dependable current limitation with a durable 22 × 58 mm ceramic body.
Its gG operating characteristic enables the FR22GG69V50P to protect cables, motors, low-voltage networks and connected electrical equipment across the complete overcurrent range. During a fault, the fuse-link rapidly limits and interrupts excessive current, helping reduce thermal and mechanical stress on downstream components.
Rated at 50 A, 690 V AC and 250 V DC, this fuse-link provides a high 120 kA AC breaking capacity. Its integrated striker can activate an auxiliary contact in a compatible fuse holder, supporting remote fault indication, alarm signalling and coordinated equipment shutdown.

Reliable Full-Range Circuit Protection
The Mersen FR22GG69V50P 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 industrial power distribution, cable protection and equipment protection.
The fuse-link's current-limiting action reduces the peak current and energy passed to downstream equipment during a fault. When the fuse operates, its striker can activate an auxiliary contact in a compatible holder, supporting remote alarms, control interlocking or automatic equipment shutdown.
Typical Applications
- Industrial electrical distribution systems.
- Cable and conductor protection.
- Low-voltage power networks.
- Motor and machinery circuits.
- Automation and control panels.
- Switchboards and OEM electrical equipment.
