Why Choose the Mersen FR22AM69V50P Cylindrical Fuse-Link?
The Mersen FR22AM69V50P is a high-performance aM cylindrical fuse-link designed to provide dependable short-circuit protection for motor circuits, industrial switchgear and machinery. Part of the Mersen range of low-voltage IEC fuses, it combines high current-limiting performance with a robust 22 × 58 mm ceramic body.
As an aM partial-range fuse-link, the FR22AM69V50P is engineered to withstand normal motor starting currents while rapidly interrupting dangerous short-circuit currents. It should be used alongside a suitable overload protection device, such as a motor protection relay, to provide coordinated motor circuit protection.
Rated at 50 A and 690 V AC, this fuse-link has a high 120 kA breaking capacity. The integrated striker can operate an auxiliary contact in a compatible fuse holder, allowing remote fuse status indication or coordinated switching within an industrial control system.
Key Advantages
- Reliable short-circuit protection for industrial motor circuits.
- 50 A rated current for demanding motor control applications.
- 690 V AC voltage rating suitable for industrial power systems.
- 120 kA breaking capacity for effective interruption of high fault currents.
- Integrated striker indication system for operating an auxiliary contact.
- Current-limiting performance helps reduce thermal and mechanical damage.

Reliable Protection for Industrial Motor Circuits
The Mersen FR22AM69V50P limits the damaging energy passed through an electrical system during a short circuit. Its aM operating characteristic allows normal motor starting currents to pass without unnecessary operation while providing rapid interruption when severe fault currents occur.
The integrated striker provides a mechanical indication when the fuse operates. When installed in a compatible fuse holder, the striker can activate an auxiliary contact for remote signalling, alarm functions or disconnection of associated control equipment.
Typical Applications
- Industrial motor starter circuits.
- Motor control centres and switchgear.
- Manufacturing and processing machinery.
- Industrial pumps, fans and compressors.
- Automation and control panels.
- OEM equipment and machine-building applications.
