Why Choose the Mersen FR14AM50V32P Cylindrical Fuse-Link?
The Mersen FR14AM50V32P is a high-performance 14 × 51 mm aM cylindrical fuse-link with striker, designed to provide dependable short-circuit protection for motors, contactors and associated industrial switching equipment. Its partial-range operating characteristic makes it particularly suitable for motor circuits where overload protection is provided separately by a correctly selected thermal or electronic overload relay.
As part of the established Mersen FR14 aM ferrule fuse-link range, this fuse combines strong current-limiting performance with a durable ceramic body and silver-plated contacts. These features help reduce thermal and mechanical stress on electrical equipment during severe fault conditions while supporting reliable operation in demanding industrial environments.
With a rated current of 32 A, an IEC rated voltage of 500 V AC and a standard 14 × 51 mm cylindrical format, the FR14AM50V32P is suitable for industrial motor starters, machinery control panels and automation equipment. Its integrated striker can operate a compatible auxiliary contact to provide fuse-status indication, remote signalling or interlocking functionality.
Key Advantages
- Purpose-designed for motor circuit short-circuit protection.
- 32 A rated current for industrial motor and machinery applications.
- 500 V AC IEC voltage rating.
- Integrated striker for indication and auxiliary contact operation.
- aM characteristic accommodates normal motor starting currents.
- High current-limiting performance helps reduce damaging fault energy.

Reliable Motor Circuit Protection with Striker Indication
The Mersen FR14AM50V32P protects motors and associated switching equipment against damaging short-circuit currents. Its aM characteristic is designed to tolerate the temporary current surge produced during motor starting while interrupting dangerous fault currents before they can cause extensive damage.
The integrated striker provides a mechanical response when the fuse operates. When installed in a compatible fuse holder, it can activate an auxiliary contact for remote fault indication, equipment shutdown or electrical interlocking. As an aM partial-range fuse-link, it must be coordinated with a suitable overload protection device.
Typical Applications
- Industrial motor starters.
- Motor control centres.
- Machinery control panels.
- Contactors and motor switching assemblies.
- Control circuits requiring fuse-status signalling.
- OEM production and automation equipment.
