Why Choose the Mersen FR22AM50V100 Cylindrical aM Fuse?
The Mersen FR22AM50V100 is a high-performance aM cylindrical fuse-link developed for short-circuit protection in industrial motor circuits and electrical switchgear. With a rated current of 100 A and an operating voltage of 500 V AC, it provides effective current limitation for demanding motor control and machinery applications.
Part of the Mersen range of 22 x 58 mm IEC ferrule fuse-links, the FR22AM50V100 uses a partial-range aM operating characteristic. It is designed to interrupt high fault currents while allowing the temporary starting currents commonly produced by electric motors. Separate overload protection should therefore be provided by a suitable overload relay or motor protection device.
The fuse features a robust ceramic body and silver-plated copper ferrules for reliable electrical contact and thermal performance. Its high 120 kA AC breaking capacity makes it suitable for industrial installations with substantial prospective fault currents.
Key Advantages
- Purpose-designed aM fuse-link for motor circuit protection.
- 100 A rated current for industrial motors and switchgear.
- 500 V AC IEC voltage rating.
- High 120 kA AC breaking capacity.
- Current-limiting performance helps reduce the effects of short-circuit faults.
- Ceramic body and silver-plated copper ferrules provide dependable operation.
Key Features
- Mersen FR22 aM ferrule fuse-link series.
- 22 x 58 mm cylindrical format.
- 100 A rated current.
- 500 V AC rated voltage.
- aM partial-range operating characteristic.
- 120 kA maximum AC breaking capacity.
- Silver-plated copper ferrule terminals.
- High-strength ceramic insulating body.
Reliable Short-Circuit Protection for Motor Circuits
The Mersen FR22AM50V100 is designed to protect motor circuit switchgear and associated electrical equipment against damaging short-circuit currents. Its aM characteristic permits normal motor starting currents while rapidly interrupting severe fault currents that could otherwise damage contactors, cables and control equipment.
As an aM partial-range fuse, the FR22AM50V100 must be used alongside a separate overload protection device. When correctly coordinated with a contactor and overload relay, it provides an effective and reliable motor starter protection system.
Typical Applications
- Industrial motor starter circuits.
- Motor control centres.
- Contactors and overload relay assemblies.
- Pumps, fans and compressor systems.
- Conveyors and material handling machinery.
- Industrial control panels and OEM equipment.
