Why Choose the Mersen FR22AM69V6 Cylindrical Fuse?
The Mersen FR22AM69V6 is a high-performance 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 fuse range, it delivers effective current limitation for motor circuits operating in demanding industrial environments.
Its aM partial-range operating characteristic allows the fuse to withstand the high inrush currents produced during normal motor starting while rapidly interrupting destructive short-circuit currents. This helps protect contactors, cables, motor starters and other downstream components against the thermal and mechanical effects of electrical faults.
With a rated current of 6 A, an IEC rated voltage of 690 V AC and a compact 22 × 58 mm cylindrical format, the FR22AM69V6 is suitable for motor control centres, industrial machinery and OEM equipment. As an aM fuse, it should normally be used alongside a suitable overload relay or motor protection device.
Key Advantages
- Designed specifically for motor circuit short-circuit protection.
- 6 A rated current for low-current industrial motor circuits.
- 690 V AC IEC rated voltage for higher-voltage applications.
- aM characteristic accommodates normal motor starting currents.
- Current-limiting performance helps reduce thermal and mechanical stress.
- Robust ceramic construction for reliable industrial operation.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen FR22AM69V6 helps protect motors and associated electrical equipment by rapidly limiting and interrupting severe short-circuit currents. Its low thermal energy let-through can reduce damage to contactors, conductors, switchgear and other components during fault conditions.
Because the FR22AM69V6 uses an aM partial-range characteristic, it is intended primarily for short-circuit protection rather than sustained overload protection. A correctly selected overload relay, motor protection relay or motor circuit breaker should therefore be included in the motor control system.
Typical Applications
- Industrial motor starter circuits.
- Motor control centres and switchgear.
- Contactors and motor protection assemblies.
- Pumps, fans and conveyor systems.
- Industrial machinery and production equipment.
- OEM automation and machine-building systems.
