Why Choose the Mersen FR22AM69V32P Cylindrical Fuse with Striker?
The Mersen FR22AM69V32P is a high-performance 22 × 58 mm aM cylindrical fuse-link with striker designed to provide dependable short-circuit protection for motors, motor starters and industrial switchgear. As part of the established Mersen FR22 aM fuse range, it offers effective current limitation and low thermal let-through performance for demanding motor control applications.
Its aM partial-range operating characteristic allows the fuse to withstand the high inrush currents associated with motor starting while rapidly interrupting dangerous short-circuit currents. The fuse should normally be used alongside a suitable overload relay, motor protection relay or motor circuit breaker to provide complete motor circuit protection.
With a rated current of 32 A, an IEC rated voltage of 690 V AC and a high 120 kA breaking capacity, the FR22AM69V32P is suitable for motor control centres, industrial machinery and electrical installations operating at elevated voltages. Its integrated striker can activate a compatible auxiliary contact when the fuse operates.

Reliable Motor Protection with Striker Indication
The Mersen FR22AM69V32P helps protect motor circuit equipment from damaging short-circuit currents by limiting peak current and reducing the thermal energy passed into downstream components. This helps minimise potential damage to contactors, cables, switchgear and other electrical equipment during severe faults.
When the fuse operates, its integrated striker extends mechanically. In a compatible fuse holder, this movement can activate an auxiliary contact for remote fault indication, alarm signalling, control-system feedback or equipment shutdown, helping maintenance teams identify and respond to faults quickly.
Typical Applications
- Industrial motor starter circuits.
- Motor control centres and switchgear.
- Contactors and motor protection assemblies.
- Pumps, fans, conveyors and compressors.
- Industrial machinery and production equipment.
- OEM automation and machine-building systems.
