Why Choose the Mersen FR22AM69V8 Cylindrical Fuse-Link?
The Mersen FR22AM69V8 is a reliable 22 × 58 mm aM cylindrical fuse-link designed to provide short-circuit protection for motors, contactors and associated industrial switching equipment. As part of Mersen’s IEC cylindrical fuse range, it is suitable for demanding motor circuits where overload protection is provided separately.
Its aM partial-range operating characteristic allows the fuse-link to withstand normal motor starting currents while rapidly limiting severe short-circuit currents. This helps protect electrical equipment from damaging thermal and mechanical stresses while supporting dependable operation in industrial control systems.
With an 8 A current rating, 690 V AC rated voltage and standard 22 × 58 mm cylindrical format, the FR22AM69V8 is suitable for motor starters, machine control panels, motor control centres and OEM automation equipment. Its ceramic body and silver-plated contacts provide durable performance in industrial electrical installations.

Reliable Motor Circuit Protection
The Mersen FR22AM69V8 is intended to protect motor circuits against damaging short-circuit currents. Its aM characteristic is coordinated with the high inrush currents produced when motors start, reducing the risk of unnecessary fuse operation during normal acceleration.
Because an aM fuse-link does not provide complete overload protection, it should be installed with a correctly selected thermal or electronic overload relay. Together, these devices provide coordinated protection for motors, cables, contactors and starter assemblies.
Typical Applications
- Industrial motor starters.
- Motor control centres.
- Machinery control panels.
- Contactors and motor switching equipment.
- Factory automation systems.
- OEM production and processing machinery.
