Why Choose the Mersen FR10AM50V8I Cylindrical aM Fuse?
The Mersen FR10AM50V8I is a compact aM cylindrical fuse-link with visual indicator, designed to provide reliable short-circuit protection for industrial motor circuits and associated switchgear. Rated at 8 A and 500 V AC, this 10 x 38 mm IEC fuse is suitable for motor starters, contactors, machinery and automation equipment.
Part of the Mersen range of 10 x 38 mm aM ferrule fuse-links, the FR10AM50V8I uses a partial-range operating characteristic that allows normal motor starting currents while rapidly interrupting damaging short-circuit currents. A separate overload relay or motor protection device should be used to protect the circuit against sustained overload conditions.
The fuse features a ceramic insulating body, silver-plated copper ferrules and an integrated visual fuse operation indicator. Its high 120 kA AC breaking capacity and current-limiting performance help protect contactors, conductors and control equipment in demanding industrial installations.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen FR10AM50V8I is designed to protect motor circuit switchgear and connected electrical equipment against unacceptable short-circuit currents. Its current-limiting operation helps reduce thermal and mechanical stress on contactors, cables and control components during severe electrical faults.
The integrated visual indicator allows maintenance engineers to identify an operated fuse quickly during inspection. As an aM partial-range fuse-link, it should be coordinated with a suitable overload relay or motor protection device to provide complete motor circuit protection.
Typical Applications
- Industrial motor starter circuits.
- Motor control centres.
- Contactors and overload relay assemblies.
- Machine control cabinets.
- Industrial automation equipment.
- Pumps, fans, conveyors and motor-driven machinery.
