Why Choose the Mersen FR8AM40V6 Cylindrical Fuse-Link?
The Mersen FR8AM40V6 is a high-quality aM cylindrical fuse-link designed to provide dependable short-circuit protection for motors, motor starters and industrial control equipment. As part of the trusted Mersen 8 × 32 mm IEC ferrule fuse range, this fuse is specifically engineered for motor protection applications where high fault interruption capability and reliable current limitation are essential.
Featuring an aM utilisation category, the FR8AM40V6 is intended for protecting motor circuits against damaging short-circuit currents while allowing normal motor starting currents to pass without nuisance operation. It should be used alongside an appropriate overload protection device to provide complete motor circuit protection.
Rated at 6 A with a 400 V AC IEC voltage rating, this compact fuse-link combines a ceramic body, silver-plated contacts and a 20 kA breaking capacity, making it ideal for industrial control panels, switchgear and OEM machinery.

Reliable Protection for Industrial Motor Circuits
The Mersen FR8AM40V6 is designed to protect motors, contactors and associated switchgear against damaging short-circuit currents. Its aM operating characteristic allows normal motor inrush currents while rapidly interrupting severe fault currents, helping minimise equipment damage and production downtime.
Because the fuse provides partial-range protection, it should always be coordinated with an overload relay or motor protection circuit breaker to provide complete protection against overloads and short circuits.
Typical Applications
- Motor starters.
- Motor control centres.
- Industrial switchgear.
- Electrical control panels.
- OEM machinery.
- Industrial automation systems.
