Why Choose the Mersen FR22AM69V20P Cylindrical Fuse-Link?
The Mersen FR22AM69V20P is a high-performance 22 × 58 mm aM cylindrical fuse-link with striker designed to provide dependable short-circuit protection for industrial motor circuits and associated switchgear. Manufactured for IEC low-voltage applications, it is suitable for motor starters, control panels and machinery requiring reliable protection against severe fault currents.
As part of the established Mersen FR22 aM ferrule fuse-link range, this model features a robust ceramic body with silver-plated copper contacts for consistent electrical performance and long service life. Its aM partial-range characteristic allows normal motor starting currents to pass while rapidly interrupting unacceptable short-circuit currents that could damage motors, contactors and installation switchgear.
With a rated current of 20 A, an IEC rated voltage of 690 V AC and a high 120 kA breaking capacity, the FR22AM69V20P is well suited to demanding industrial motor protection applications. Its integrated striker can activate a compatible auxiliary contact, supporting remote fault indication, alarms and control functions.

Reliable Protection for Industrial Motor Circuits
The Mersen FR22AM69V20P is designed to protect motor circuits and associated switchgear against damaging short-circuit currents. Its aM characteristic permits temporary motor starting currents while providing high current limitation and low thermal let-through during severe electrical faults.
Because an aM fuse-link provides partial-range protection, it should normally be coordinated with a suitable motor overload relay. The integrated striker can operate a compatible auxiliary contact when the fuse blows, enabling remote indication, alarm signalling or automatic equipment shutdown.
Typical Applications
- Industrial motor starters.
- Motor control centres.
- Contactors and overload relay assemblies.
- Electrical control panels.
- Machine building and OEM equipment.
- Industrial automation and switchgear systems.
