Why Choose the Mersen FR10AM40V2P Cylindrical aM Fuse?
The Mersen FR10AM40V2P is a compact aM cylindrical fuse-link with striker designed to protect industrial motor circuits and associated switchgear against damaging short-circuit currents. Rated at 2 A and 400 V AC, this fuse is suitable for low-current motor control, machinery and industrial automation applications.
Part of the Mersen range of 10 x 38 mm IEC ferrule fuse-links, the FR10AM40V2P uses an aM partial-range operating characteristic. It provides effective current limitation during severe faults while allowing the temporary inrush currents associated with motor starting. A suitable overload relay or motor protection device must be used separately to protect against sustained overload conditions.
The fuse incorporates a robust ceramic body, silver-plated copper ferrules and an integrated striker indication system. Its high 100 kA AC breaking capacity enables it to interrupt substantial prospective fault currents safely, while the striker can support remote fuse status indication or electrical interlocking when installed in compatible equipment.
Key Advantages
- Purpose-designed aM protection for industrial motor circuits.
- 2 A rated current for low-current machinery and control applications.
- 400 V AC IEC voltage rating.
- Integrated striker for fuse operation indication.
- High 100 kA AC breaking capacity.
- Current-limiting performance helps reduce damage to switchgear and connected equipment.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen FR10AM40V2P is engineered to protect motor circuit switchgear and connected electrical equipment from excessive short-circuit currents. Its current-limiting behaviour helps reduce thermal and mechanical stress on contactors, conductors and other components during severe electrical faults.
As an aM partial-range fuse-link, this product is not designed to provide overload protection. It should be coordinated with a suitable overload relay or motor protection device to create a complete motor starter protection system.
Typical Applications
- Industrial motor starter circuits.
- Motor control centres.
- Contactors and overload relay assemblies.
- Machine control cabinets.
- Industrial automation equipment.
- Pumps, fans and low-current motor-driven machinery.
