Why Choose the Mersen FR10AM40V32 Cylindrical Fuse Link?
The Mersen FR10AM40V32 is a compact and dependable 10 × 38 mm aM cylindrical fuse link designed to protect motor circuits and associated industrial equipment against damaging short-circuit currents. Rated at 32 A and 400 V AC, it is suitable for motor starters, control panels and industrial machinery where reliable fault protection is essential.
As an aM partial-range fuse link, the FR10AM40V32 is specifically designed for circuits containing motors and other loads with high starting currents. Its operating characteristic allows normal motor inrush currents to pass while rapidly interrupting severe short-circuit faults that could damage contactors, cables and connected equipment.
The fuse features a robust ceramic body and silver-plated contacts for reliable electrical performance in demanding environments. Its standard 10 × 38 mm cylindrical construction enables straightforward installation in compatible fuse holders and mounting clips within motor control centres, switchboards and OEM machinery.
Key Advantages
- Reliable short-circuit protection for industrial motor circuits.
- 32 A rated current for motor control applications.
- 400 V AC rated voltage for low-voltage industrial systems.
- High 120 kA AC breaking capacity for effective fault interruption.
- aM partial-range characteristic accommodates motor starting currents.
- Compact 10 × 38 mm cylindrical format for space-efficient installation.
Key Features
- Mersen FR10 aM cylindrical fuse-link series.
- 32 A rated current.
- 400 V AC IEC rated voltage.
- aM motor protection characteristic.
- 120 kA AC breaking capacity.
- High current-limiting performance during short-circuit faults.

- Durable ceramic insulating body.
- Silver-plated cylindrical contacts.
- Manufactured in accordance with IEC 60269 requirements.
Reliable Short-Circuit Protection for Motor Circuits
The Mersen FR10AM40V32 is engineered for circuits supplying motors and other inductive equipment that can draw substantial current during starting. Its aM characteristic helps prevent nuisance operation during normal acceleration while providing rapid current limitation when a serious short-circuit fault occurs.
Because an aM fuse provides partial-range protection, it should be coordinated with a suitable thermal or electronic overload relay. Together, these devices help protect motors, contactors, cables and associated control equipment against overload conditions and high fault currents.
Typical Applications
- Industrial motor control circuits.
- Direct-on-line and reversing motor starters.
- Motor control centres and switchboards.
- Pumps, fans, conveyors and compressors.
- Industrial machinery and production equipment.
- OEM control panels and automation systems.
- Transformers and other high-inrush loads.
