Why Choose the Mersen FR22AM50V80P Cylindrical aM Fuse?
The Mersen FR22AM50V80P is a high-performance aM cylindrical fuse-link with striker designed to provide dependable short-circuit protection for industrial motor circuits and associated switchgear. Rated at 80 A and 500 V AC, this 22 x 58 mm IEC fuse is suitable for protecting motor starters, contactors and electrical equipment in demanding industrial applications.
Part of the Mersen range of 22 x 58 mm aM ferrule fuse-links, the FR22AM50V80P uses a partial-range operating characteristic. It allows the temporary inrush currents generated during normal motor starting while rapidly interrupting damaging short-circuit currents. A separate overload relay or motor protection device is therefore required to provide protection against sustained overload conditions.
The fuse incorporates a robust ceramic body, silver-plated contacts and an integrated striker mechanism. The striker can activate a compatible auxiliary contact for remote fuse status indication or electrical interlocking, helping operators identify faults quickly and reduce machinery downtime.
Key Advantages
- Purpose-designed aM short-circuit protection for motor circuits.
- 80 A rated current for industrial motor applications.
- 500 V AC IEC voltage rating.
- Integrated striker for remote fuse operation signalling.
- High breaking capacity for demanding industrial fault conditions.
- Current-limiting operation helps reduce damage to switchgear and connected equipment.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen FR22AM50V80P is engineered to protect motor circuit switchgear against unacceptable short-circuit currents. Its current-limiting performance helps reduce the thermal and mechanical energy transferred to contactors, cables and other connected components during severe electrical faults.
The integrated striker provides mechanical indication when the fuse has operated and can activate a compatible auxiliary contact for remote monitoring or interlocking. As an aM partial-range fuse-link, it must be coordinated with a suitable overload relay or motor protection device to create a complete motor circuit protection system.
Typical Applications
- Industrial motor starter circuits.
- Motor control centres.
- Contactors and overload relay assemblies.
- Pumps, fans and compressor systems.
- Conveyors and production machinery.
- Industrial control panels and OEM equipment.
