Why Choose the Mersen NH000AM69V16 Motor Fuse Link?
The Mersen NH000AM69V16 is a compact and reliable DIN NH aM fuse link designed specifically for short-circuit protection in industrial motor circuits. As part of the Mersen NH aM fuse-link range, it provides strong current-limiting performance and low power losses, helping protect motors, contactors, cables and associated switching equipment against damaging fault currents.
This fuse link features a rated current of 16 A and a maximum operating voltage of 690 V AC. Its aM operating class is optimised for motor applications where high starting currents are expected, allowing the fuse to withstand normal motor inrush while rapidly interrupting severe short-circuit currents.
Manufactured in the compact NH000 size, the NH000AM69V16 has a body width of approximately 21 mm and incorporates blade contacts, live gripping lugs and a double indicator. It must be used with suitable overload protection, such as a motor protection relay or circuit breaker, because an aM fuse provides short-circuit protection rather than full-range overload protection.
Key Advantages
- Purpose-designed aM fuse link for motor circuit protection.
- 16 A rated current for smaller industrial motor applications.
- 690 V AC voltage rating suitable for industrial power systems.
- Strong current-limiting performance helps reduce fault energy.
- Designed to tolerate normal motor starting currents.
- Double indicator enables convenient visual identification of fuse operation.
- Compact NH000 format saves space in electrical panels and switchgear.

Reliable Short-Circuit Protection for Motor Circuits
Motor circuits can draw several times their normal operating current during starting. The Mersen NH000AM69V16 is engineered to accommodate these temporary starting currents while providing fast interruption when a severe short circuit occurs. Its current-limiting characteristics help reduce the thermal and mechanical stress placed on downstream components.
Because this is an aM partial-range fuse, it must be coordinated with a suitable overload protection device. When correctly selected and installed, this combination provides effective protection for motors, contactors, starters and associated conductors in industrial machinery and automation systems.
Typical Applications
- Industrial motor starter circuits.
- Motor control centres.
- Pumps, fans and compressor systems.
- Conveyors and material handling machinery.
- Industrial automation equipment.
- Electrical switchboards and control panels.
