Why Choose the Mersen FR14AM69V8 Cylindrical Fuse Link?
The Mersen FR14AM69V8 is a high-performance aM cylindrical fuse link engineered to provide reliable short-circuit protection for motor circuits and industrial electrical equipment. As part of the trusted Mersen 14 × 51 mm ferrule fuse range, it is specifically designed for applications where motors generate high starting currents and require dependable fault protection without nuisance operation.
Manufactured with a robust ceramic body and silver-plated contacts, the FR14AM69V8 offers excellent current-limiting characteristics and a high breaking capacity. Its aM operating characteristic allows motor starting currents to pass while rapidly interrupting damaging short-circuit currents, making it ideal for coordinated motor protection systems.
With a rated current of 8 A, a 690 V AC rating and a compact 14 × 51 mm IEC format, the FR14AM69V8 is well suited to motor starters, control panels, switchgear and OEM machinery operating in demanding industrial environments.

Reliable Protection for Motor Control Systems
The Mersen FR14AM69V8 is engineered to interrupt high fault currents whilst allowing the temporary inrush currents associated with motor starting. Its current-limiting characteristics help minimise thermal and mechanical stress on motors, contactors and associated electrical equipment during fault conditions.
As an aM fuse, it is intended for use alongside a correctly selected overload relay or motor protection device, providing coordinated protection for industrial motors, machinery and automation systems.
Typical Applications
- Motor starters.
- Industrial control panels.
- Motor control centres.
- OEM machinery.
- Industrial switchgear.
- Automation and manufacturing equipment.
