Why Choose the Mersen FR22AM69V4P Cylindrical Fuse Link?
The Mersen FR22AM69V4P is a high-performance 22 × 58 mm cylindrical aM fuse link designed to provide dependable short-circuit protection for motors, contactors and industrial electrical equipment. Rated at 4 A and 690 V AC, it is suitable for demanding motor control and power distribution applications.
As an aM utilisation category fuse, the FR22AM69V4P provides partial-range protection against high short-circuit currents while allowing the temporary inrush currents produced during motor starting. It should be coordinated with a correctly selected overload relay, motor protection circuit breaker or equivalent device to provide complete motor circuit protection.
The fuse link includes an integrated striker mechanism that can activate a compatible auxiliary contact when the fuse operates. Its durable ceramic body and silver-plated contacts provide dependable electrical performance, effective current limitation and reliable operation in industrial control panels, switchgear and machinery.

Reliable Short-Circuit Protection for Motor Circuits
Electric motors can draw significantly more than their normal operating current during start-up. The aM operating characteristic allows the Mersen FR22AM69V4P to tolerate these temporary starting currents while responding rapidly to destructive short-circuit faults.
Because the FR22AM69V4P is a partial-range fuse, it should be installed alongside a suitable overload protection device. This coordinated arrangement helps protect motors, cables, contactors and associated control equipment against both sustained overloads and high fault currents.
Typical Applications
- Industrial motor starters.
- Motor control centres and control panels.
- Contactors and overload relay assemblies.
- Pumps, fans and conveyor systems.
- Industrial machinery and automation equipment.
- Switchgear and power distribution assemblies.
