Why Choose the Mersen FR14AM69V32 Cylindrical Fuse Link?
The Mersen FR14AM69V32 is a robust 14 × 51 mm cylindrical aM fuse link designed to protect industrial motor circuits and associated switchgear against damaging short-circuit currents. Rated at 32 A and 690 V AC, it is suitable for demanding motor control panels, machinery and electrical distribution applications.
As part of the Mersen FR14 ferrule fuse-link range, the FR14AM69V32 uses an aM partial-range operating characteristic. It is engineered to tolerate normal motor starting currents while interrupting unacceptable high-current faults that could damage contactors, cables, motor starters and other connected components.
The fuse combines a durable ceramic body with silver-plated copper ferrule contacts for dependable electrical performance. Its high 120 kA AC breaking capacity, effective current limitation and low thermal energy let-through make it a reliable choice for coordinated motor circuit protection in industrial environments.

Reliable Short-Circuit Protection for Motor Circuits
An aM fuse link is designed specifically for partial-range protection of motor circuits. The Mersen FR14AM69V32 interrupts severe fault currents while allowing the temporary inrush currents produced during normal motor starting, helping prevent unnecessary fuse operation.
Because an aM fuse does not provide full overload protection, it should normally be coordinated with a suitable thermal or electronic overload relay. The overload device protects against sustained overcurrent conditions, while the fuse rapidly limits and interrupts high short-circuit currents.
Typical Applications
- Industrial motor starters and control panels.
- Motor control centres and switchgear assemblies.
- Pumps, fans and compressor circuits.
- Conveyors and material handling equipment.
- Manufacturing and processing machinery.
- Electrical loads with high starting or inrush currents.
