Why Choose the Mersen FR10AM40V25I Cylindrical Fuse-Link?
The Mersen FR10AM40V25I is a reliable aM cylindrical fuse-link with visual indicator, designed to provide short-circuit protection for motors, industrial machinery and associated electrical equipment. Part of the established Mersen FR10AM range, it combines dependable current limitation with a compact 10 × 38 mm format.
As an aM partial-range fuse-link, the FR10AM40V25I is designed to tolerate normal motor starting currents while rapidly interrupting dangerous short-circuit currents. It should be coordinated with a suitable overload relay or motor protection device to provide complete protection against both overloads and short circuits.
Rated at 25 A and 400 V AC, this fuse-link offers a high 120 kA AC breaking capacity. Its integrated visual indicator provides a clear indication when the fuse has operated, helping maintenance engineers identify faults and restore equipment operation efficiently.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen FR10AM40V25I protects motor circuits by limiting and interrupting unacceptable short-circuit currents before they can cause significant damage to motors, contactors, conductors and switchgear. Its aM operating characteristic allows the temporary inrush current associated with motor starting to pass without unnecessary fuse operation.
During a severe electrical fault, the fuse-link limits the peak current and thermal energy passed to downstream equipment. The built-in visual indicator also makes it easier to identify an operated fuse during maintenance, helping reduce diagnostic time and equipment downtime.
Typical Applications
- Industrial motor starter circuits.
- Motor control centres and switchgear.
- Pumps, fans and compressor systems.
- Manufacturing and processing machinery.
- Automation and control panels.
- OEM equipment and machine-building applications.
