Why Choose the Mersen FR22AM69V25 Cylindrical Fuse Link?
The Mersen FR22AM69V25 is a reliable 22 × 58 mm aM cylindrical fuse link designed to protect motors, transformers and other industrial loads with high starting currents against damaging short-circuit faults. Rated at 25 A and 690 V AC, it is suitable for demanding motor control and industrial electrical applications.
As an aM partial-range fuse link, the FR22AM69V25 is engineered to withstand the temporary inrush currents produced during motor starting while rapidly interrupting severe fault currents. Its current-limiting performance helps reduce thermal and mechanical stress on contactors, conductors and associated switchgear.
The fuse features a durable ceramic body and silver-plated copper ferrule contacts for dependable electrical performance and long service life. Its standard cylindrical construction allows straightforward installation in compatible 22 × 58 mm fuse holders and mounting clips used in motor control centres, switchboards and industrial machinery.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen FR22AM69V25 is designed for circuits containing motors and other inductive equipment that can draw substantial current during starting. Its aM operating characteristic allows normal inrush currents to pass while providing rapid protection when a high short-circuit current occurs.
Because an aM fuse provides partial-range protection, it should be coordinated with a suitable thermal or electronic overload relay. Together, these devices help protect motors, cables, contactors and associated control equipment against overloads and short-circuit faults.
Typical Applications
- Industrial motor control circuits.
- Direct-on-line and reversing motor starters.
- Motor control centres and switchboards.
- Pumps, fans, conveyors and compressors.
- Transformers and high-inrush inductive loads.
- Industrial machinery and production equipment.
- OEM control panels and automation systems.
