Why Choose the Mersen FR22AM69V25P Cylindrical Fuse-Link?
The Mersen FR22AM69V25P is a high-performance aM cylindrical fuse-link with striker, designed to provide dependable short-circuit protection for motors, motor starters and associated industrial switchgear. Part of the Mersen 22 × 58 mm ferrule fuse-link range, it is rated for motor circuits operating at voltages up to 690 V AC.
Its aM partial-range characteristic allows the fuse-link to tolerate the temporary inrush currents produced during normal motor starting while rapidly interrupting dangerous short-circuit currents. The FR22AM69V25P should be coordinated with a suitable overload relay or motor protection device because an aM fuse-link does not provide complete overload protection on its own.
With a rated current of 25 A, a high breaking capacity of 120 kA and an integrated striker indication system, this fuse-link provides reliable protection and clear fault signalling. Its ceramic body, silver-plated copper terminals and standard 22 × 58 mm format make it suitable for motor control panels, industrial machinery and automation equipment.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen FR22AM69V25P limits and interrupts high short-circuit currents before they can cause serious damage to motors, contactors, cables and motor control equipment. Its low thermal let-through and current-limiting performance help reduce the energy passed into the protected circuit during a fault.
The integrated striker provides a mechanical indication when the fuse-link operates and can activate a compatible auxiliary contact in the fuse holder. This helps maintenance personnel identify a failed circuit quickly and can support remote fault monitoring within industrial control systems.

- Industrial motor control panels.
- Motor control centres.
- Pumps, fans and conveyor systems.
- Manufacturing and processing machinery.
