Why Choose the Mersen FR22AM69V80 Cylindrical Fuse Link?
The Mersen FR22AM69V80 is a high-performance 22 × 58 mm aM cylindrical fuse link designed to protect motor circuits and associated switchgear against damaging short-circuit currents. Rated at 80 A and 690 V AC, it is suitable for demanding industrial installations where reliable current limitation and dependable fault interruption are essential.
As an aM partial-range fuse, the FR22AM69V80 is specifically developed for motor circuit protection. Its operating characteristic allows normal motor starting currents to pass while rapidly interrupting severe short-circuit faults. For complete protection, it should be coordinated with a suitable overload relay or other overload protection device.
The fuse features a robust ceramic body and durable silver-plated copper ferrule contacts. Its compact cylindrical format allows straightforward installation in compatible 22 × 58 mm fuse holders or mounting clips, making it ideal for motor control centres, industrial control panels and OEM machinery.

Reliable Protection for High-Power Motor Circuits
The Mersen FR22AM69V80 is designed to interrupt fault currents above the normal operating and starting range of industrial motors. Its aM characteristic offers effective short-circuit protection while reducing the risk of nuisance operation during normal motor acceleration.
When coordinated with a correctly selected overload relay, the fuse helps protect motors, contactors, cables and other motor control equipment. Its high current-limiting capability reduces thermal and mechanical stress during faults, helping minimise equipment damage and system downtime.
Typical Applications
- Industrial motor control circuits.
- Motor control centres and switchboards.
- Direct-on-line and reversing motor starters.
- Pumps, fans, compressors and conveyors.
- Industrial machinery and production equipment.
- OEM control panels and automation systems.
- High-inrush inductive loads.
