Why Choose the Mersen NH1AM69V80P-2 NH Fuse Link?
The Mersen NH1AM69V80P-2 is a high-performance NH1 aM fuse link designed to provide dependable short-circuit protection for industrial motors and associated electrical circuits. Manufactured to the DIN NH format, this partial-range fuse is engineered to tolerate normal motor starting currents while rapidly interrupting damaging fault currents.
With a rated current of 80 A and a maximum operating voltage of 690 V AC, the NH1AM69V80P-2 is suitable for motor control centres, industrial switchgear and high-demand machinery applications. Its strong current-limiting performance helps reduce thermal and mechanical stress on contactors, cables, motor starters and other connected components.
The fuse incorporates an integrated striker indication system that can activate a compatible signalling device or switch mechanism after operation. Its ceramic body, silver-plated copper blade contacts and standard NH1 construction provide reliable electrical performance and straightforward installation in compatible NH fuse bases and switch-fuse assemblies.

Reliable Short-Circuit Protection for Motor Circuits
Type aM fuse links are partial-range protection devices developed specifically for motor circuits. They interrupt high fault currents while allowing the temporary inrush currents produced during normal motor starting, helping prevent unnecessary fuse operation in correctly coordinated installations.
The Mersen NH1AM69V80P-2 must be combined with a suitable overload protection device, such as a thermal overload relay or motor protection circuit breaker. This coordinated arrangement provides complete protection against both overload and short-circuit conditions.
Typical Applications
- Industrial motor control centres.
- Motor starters and contactor assemblies.
- Pumps, fans and compressors.
- Conveyors and material handling systems.
- Manufacturing and processing machinery.
- Industrial switchgear and fuse disconnectors.
- Automation and production equipment.
