Why Choose the Mersen NH00AM69V80 NH Fuse-Link?
The Mersen NH00AM69V80 is a high-performance NH size 00 aM fuse-link designed to provide dependable short-circuit protection for industrial motors and associated electrical equipment. Rated at 80 A and 690 V AC, it is suitable for motor control centres, machinery, switchgear and low-voltage industrial distribution systems.
Its aM utilisation category provides partial-range protection specifically intended for motor circuits. The fuse-link offers strong current-limiting performance, helping reduce the thermal and mechanical effects of short-circuit currents on motors, cables, contactors and other downstream components.
The NH00AM69V80 features a durable ceramic body, silver-plated copper blade contacts, live gripping lugs and a practical double indication system. Its standard NH00 construction enables installation in compatible NH fuse bases and fuse-switch disconnectors used throughout industrial electrical systems.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen NH00AM69V80 is engineered to interrupt damaging fault currents before they can cause serious thermal or mechanical damage to motors, cables, contactors and switchgear. Its current-limiting action reduces the peak fault current and let-through energy reaching downstream components.
As an aM fuse-link, the NH00AM69V80 provides short-circuit protection only. It must therefore be coordinated with a suitable overload relay, motor protection circuit breaker or equivalent protective device to provide complete motor protection.
Typical Applications
- Industrial motor control centres.
- Motor starters and contactor assemblies.
- Pumps, fans and compressors.
- Conveyors and material handling systems.
- Machine-building and OEM control panels.
- Industrial switchboards and fuse-switch disconnectors.
