Why Choose the Mersen FR10AM40V16P Cylindrical Fuse-Link?
The Mersen FR10AM40V16P is a high-performance aM cylindrical fuse-link designed to provide dependable short-circuit protection for motors, motor starters and associated industrial control equipment. Manufactured by Mersen, it forms part of the established 10 × 38 mm IEC ferrule fuse range for low-voltage electrical installations.
Its aM partial-range operating characteristic enables the fuse to withstand the temporary inrush currents produced when motors start while providing rapid protection against dangerous short-circuit currents. It is intended to be used alongside a suitable overload protection device, such as a thermal overload relay or motor protection circuit breaker.
Rated at 16 A and 380 V AC, the FR10AM40V16P combines high current-limiting performance with a compact cylindrical format. Its integrated striker can activate a compatible auxiliary contact or signalling device when the fuse operates, helping maintenance teams identify faults quickly.

Reliable Short-Circuit Protection for Motor Circuits
Motor starting can produce current levels significantly higher than the normal running current. The aM characteristic of the Mersen FR10AM40V16P allows these temporary starting currents to pass while providing fast, current-limiting protection when a severe short circuit occurs.
Because an aM fuse does not provide full-range overload protection, it should be coordinated with an appropriate overload relay or motor protection device. This combination provides effective protection for motors, contactors, cables and associated switching equipment.
Typical Applications
- Industrial motor starters.
- Motor control centres.
- Contactors and overload relay assemblies.
- Industrial control panels.
- Machine building and OEM equipment.
- Pumps, fans and conveyor systems.
