Why Choose the Mersen FR14AM50V16P Cylindrical Fuse Link?
The Mersen FR14AM50V16P is a dependable 14 × 51 mm cylindrical aM fuse link with striker, designed to protect industrial motor circuits and associated switchgear against damaging short-circuit currents. Rated at 16 A and 500 V AC, it is suitable for motor starters, machinery panels and industrial electrical installations.
As part of the Mersen FR14 ferrule fuse-link range, the FR14AM50V16P uses an aM partial-range operating characteristic. This enables it to tolerate normal motor starting currents while rapidly interrupting severe faults that could otherwise damage contactors, cables, motor protection equipment and connected machinery.
The fuse features a robust ceramic body, silver-plated copper ferrule contacts and an integrated striker for fuse-operation indication. Its high 120 kA AC breaking capacity, low thermal energy let-through and effective current limitation make it a reliable solution for coordinated motor circuit protection.

Reliable Short-Circuit Protection for Motor Circuits
An aM fuse link provides partial-range protection specifically for motor circuits and associated switchgear. The Mersen FR14AM50V16P interrupts unacceptable high short-circuit currents while allowing the temporary inrush currents produced during normal motor starting.
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 severe 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.
