Why Choose the Mersen FR22AM69V1P Cylindrical Fuse Link?
The Mersen FR22AM69V1P is a high-performance 22 × 58 mm aM cylindrical fuse link with striker designed to provide dependable short-circuit protection for motor circuits, industrial switchgear and equipment with high starting currents. As part of the established Mersen FR22 aM ferrule fuse series, it is engineered for reliable current limitation in demanding low-voltage industrial applications.
Its aM operating characteristic allows temporary motor starting currents to pass while rapidly interrupting unacceptable short-circuit currents. This helps protect contactors, cables, switchgear and connected equipment from severe thermal and mechanical stress. As an aM partial-range fuse, it should be used alongside a suitable overload relay or equivalent overload protection device.
With a rated current of 1 A, a rated voltage of 690 V AC and a high breaking capacity of 120 kA, the FR22AM69V1P is suitable for motor control, transformer and industrial auxiliary circuits. Its integrated striker can activate a compatible auxiliary contact for remote fuse operation signalling.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen FR22AM69V1P is engineered to protect motor circuits and associated switchgear against severe short-circuit currents. Its aM time-current characteristic tolerates the temporary inrush produced during motor starting while providing effective current limitation when a damaging fault occurs.
The integrated striker provides mechanical fuse operation indication and can activate an auxiliary contact in a compatible 22 × 58 mm fuse holder. This supports remote fault signalling, faster maintenance and improved monitoring within motor control centres, machinery and industrial control panels.
Typical Applications
- Industrial motor starter circuits.
- Motor control centres.
- Transformer and inductive-load protection.
- Industrial machinery and production equipment.
- OEM electrical control panels.
- Switchgear requiring remote fuse operation indication.
