Why Choose the Mersen FR22AM69V10 Cylindrical Fuse?
The Mersen FR22AM69V10 is a robust 22 × 58 mm aM cylindrical fuse-link designed to provide dependable short-circuit protection for motors, motor starters and associated industrial switchgear. As part of the established Mersen FR22 aM range, it offers effective current limitation and low thermal let-through performance for demanding motor circuit applications.
The aM partial-range characteristic allows the fuse to tolerate the high inrush currents associated with motor starting while rapidly interrupting dangerous short-circuit currents. It is normally used alongside a suitable overload protection device, such as a motor protection relay, thermal overload relay or motor circuit breaker.
With a rated current of 10 A, an IEC rated voltage of 690 V AC and a high 120 kA breaking capacity, the FR22AM69V10 is suitable for industrial machinery, motor control centres and electrical installations requiring reliable protection at elevated operating voltages.
Key Advantages
- Designed specifically for motor circuit short-circuit protection.
- 10 A rated current for industrial motor applications.
- 690 V AC IEC rated voltage for higher-voltage systems.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen FR22AM69V10 helps protect motor circuit equipment from unacceptable short-circuit currents by limiting peak current and reducing the thermal energy passed into downstream components. This can help minimise damage to contactors, cables, switchgear and other equipment during electrical faults.
Because it uses an aM partial-range characteristic, the fuse is intended primarily for short-circuit protection rather than complete overload protection. A correctly selected overload relay or equivalent protective device should therefore be incorporated into the motor control system.
Typical Applications
- Industrial motor starter circuits.
- Motor control centres and switchgear.
- Contactors and motor protection assemblies.
- Industrial machinery and production equipment.
- Pumps, fans, conveyors and compressors.
- OEM automation and machine-building systems.
