Why Choose the Mersen FR10AM50V1 Cylindrical Fuse Link?
The Mersen FR10AM50V1 is a compact and dependable 10 × 38 mm cylindrical aM fuse link designed to protect industrial motor circuits, transformers and equipment with high inrush currents against damaging short-circuit faults. Rated at 1 A and 500 V AC, it is suitable for control panels, motor starters and machinery installations requiring reliable current limitation.
As part of the Mersen FR10 ferrule fuse-link range, the FR10AM50V1 uses an aM partial-range operating characteristic. This allows it to tolerate normal motor starting currents while rapidly interrupting severe fault currents that could damage contactors, conductors, switchgear and connected equipment.
The fuse features a durable ceramic body and silver-plated copper ferrule contacts for consistent electrical performance. Its high 120 kA AC breaking capacity, low thermal energy let-through and standard cylindrical format make it a reliable choice for coordinated motor circuit protection in demanding industrial environments.

Reliable Short-Circuit Protection for Motor Circuits
An aM fuse link is specifically designed to protect motor circuits against high short-circuit currents while allowing the temporary inrush current produced during motor starting. The Mersen FR10AM50V1 interrupts currents above its defined operating threshold while limiting the peak current and thermal energy passed into the circuit.
Because an aM fuse provides partial-range protection, it should normally be coordinated with a suitable thermal or electronic overload relay. The overload device protects against sustained overcurrent conditions, while the fuse provides rapid protection against severe short circuits.
Typical Applications
- Industrial motor starters and control panels.
- Motor control centres and switchgear assemblies.
- Transformer protection circuits.
- Pumps, fans and small motor-driven equipment.
- Manufacturing and processing machinery.
- Electrical loads with high starting or inrush currents.
