Why Choose the Mersen FR8AM40V10 Cylindrical Fuse-Link?
The Mersen FR8AM40V10 is a compact and dependable 8 × 32 mm aM cylindrical fuse-link designed to provide short-circuit protection for industrial motor circuits and associated electrical equipment. Manufactured for IEC low-voltage applications, it is suitable for motor starters, machinery and control panels requiring reliable protection against damaging fault currents.
As part of the established Mersen FR8 aM ferrule fuse-link range, the FR8AM40V10 features a durable ceramic body with silver-plated contacts for consistent electrical performance and long operational life. Its aM partial-range characteristic allows temporary motor starting currents to pass while rapidly interrupting severe short-circuit currents.
With a rated current of 10 A, a rated voltage of 400 V AC and a breaking capacity of 20 kA, the FR8AM40V10 is suitable for protecting motors, contactors and switchgear in industrial automation and machine-building applications. Its compact dimensions also support efficient installation in space-conscious electrical panels.

Reliable Protection for Industrial Motor Circuits
The Mersen FR8AM40V10 is designed to protect motors and associated equipment against unacceptable short-circuit currents. Its aM characteristic accommodates the temporary current surge produced during motor starting while providing effective current limitation during severe electrical faults.
Because an aM fuse-link does not provide full-range overload protection, it is normally used alongside a suitable motor overload relay or other protective device. This coordinated arrangement provides effective protection for motors, contactors and electrical conductors.
Typical Applications
- Industrial motor starters.
- Motor control panels.
- Contactors and overload relay assemblies.
- Machine building and OEM equipment.
- Industrial automation systems.
- Low-voltage switchgear installations.
