Why Choose the Mersen NH000AM69V32 NH Fuse Link?
The Mersen NH000AM69V32 is a compact NH000 size aM fuse link designed to provide reliable short-circuit protection for motors, motor starters and industrial machinery. Rated at 32 A and 690 V AC, it is suitable for motor control circuits where high starting currents must be accommodated without unnecessary fuse operation.
Its aM operating characteristic is specifically intended for motor circuit protection. The fuse link tolerates the temporary inrush currents produced during motor starting while rapidly interrupting dangerous short-circuit currents. As an aM fuse provides partial-range protection, it must be used with a correctly selected overload relay or another suitable overload protection device.
The NH000AM69V32 features a compact 21 mm-wide body, standard NH blade contacts and live gripping tags for handling with a compatible NH fuse puller. Its integrated double indicator provides a clear visual indication when the fuse has operated, helping maintenance personnel locate faults and replace the fuse efficiently.

Reliable Short-Circuit Protection for Motor Circuits
Electric motors can draw several times their normal operating current during start-up. The Mersen NH000AM69V32 is engineered to withstand these temporary current peaks while providing fast interruption when a serious short circuit occurs. Its current-limiting performance helps reduce thermal and electrodynamic stress on motors, cables, contactors and associated switchgear.
Because the NH000AM69V32 has an aM characteristic, it does not provide complete overload protection when used alone. A suitable thermal or electronic overload relay must be included in the motor protection system. Installation and replacement should only be carried out by qualified electrical personnel using approved NH handling equipment and appropriate personal protective equipment.
Typical Applications
- Industrial motor starters and control panels.
- Motor control centres and switchgear assemblies.
- Pumps, fans and ventilation equipment.
- Conveyors and material handling machinery.
- Compressors and processing equipment.
- Manufacturing and production machinery.
