Why Choose the Mersen NH0AM69V16 Motor Protection Fuse-Link?
The Mersen NH0AM69V16 is a compact and dependable DIN NH aM fuse-link designed to provide short-circuit protection for motor circuits and associated industrial equipment. Part of the established Mersen NH aM 690 V AC fuse-link series, it offers strong current-limiting performance for motor starters, contactors, cables and switchgear.
The specialised aM operating characteristic allows the fuse-link to tolerate the temporary starting currents produced by electric motors while responding rapidly to damaging short-circuit currents. As an aM partial-range fuse-link, it must be used alongside a suitable overload protection device, such as a thermal overload relay or motor protection circuit breaker.
With a rated current of 16 A, a rated voltage of 690 V AC and a standard NH Size 0 construction, the NH0AM69V16 is suitable for industrial motor control panels, machinery and automation systems. Its double indication system enables quick identification after operation, while the live gripping lugs support replacement using an approved NH fuse puller.
Key Advantages
- Specialised aM characteristic for motor circuit protection.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen NH0AM69V16 is designed to interrupt high fault currents before they can damage motor cables, contactors, starters or associated switchgear. Its aM characteristic accommodates normal motor starting currents while providing effective current limitation during short-circuit conditions.
Because aM fuse-links provide partial-range protection, the NH0AM69V16 does not independently protect against low-level or sustained overloads. It should be coordinated with a correctly selected overload relay or motor protection device to provide complete motor circuit protection.
Typical Applications
- Industrial electric motor circuits.
- Motor starters and contactor assemblies.
- Motor control centres.
- Pumps, fans and conveyor systems.
- Industrial machinery and production equipment.
- Automation and control panels.
- OEM switchgear and electrical assemblies.
