Why Choose the Mersen FR10AM40V10P Cylindrical Fuse Link?
The Mersen FR10AM40V10P is a compact and reliable 10 × 38 mm cylindrical aM fuse link designed to provide short-circuit protection for motors, contactors and industrial electrical equipment. Rated at 10 A and 400 V AC according to IEC requirements, it is well suited to motor control circuits, machinery and industrial power distribution systems.
As an aM utilisation category fuse, the FR10AM40V10P provides partial-range protection against damaging short-circuit currents while allowing the temporary inrush currents associated with motor starting. It should be coordinated with a suitably rated overload relay, motor protection circuit breaker or equivalent device to provide complete protection against both overload and short-circuit conditions.
The FR10AM40V10P includes an integrated striker mechanism that can operate a compatible auxiliary contact or signalling accessory when the fuse operates. Its ceramic body, silver-plated contacts and current-limiting performance make it a dependable choice for industrial control panels, motor starters and OEM machinery.
Key Advantages
- Compact 10 × 38 mm cylindrical fuse-link format.

Reliable Short-Circuit Protection for Motor Circuits
Industrial motors can draw several times their normal operating current during start-up. The aM operating characteristic allows the Mersen FR10AM40V10P to tolerate these temporary starting currents while responding rapidly to destructive short-circuit faults.
Because the FR10AM40V10P is a partial-range fuse, it should be used with a suitable overload protection device. Coordinating the fuse with an overload relay or motor protection circuit breaker helps safeguard motors, cables, contactors and associated control equipment against both overloads and short circuits.
Typical Applications
- Industrial motor starters.
- Motor control centres and control panels.
- Contactors and overload relay assemblies.
- Pumps, fans and conveyor systems.
- Industrial machinery and automation equipment.
- OEM motor control installations.
