Why Choose the Mersen NH0AM69V160 Motor Protection Fuse?
The Mersen NH0AM69V160 is a high-performance NH aM industrial fuse link designed to provide dependable short-circuit protection for motors, motor starters and associated electrical equipment. Manufactured to the DIN NH standard, this partial-range fuse is engineered for demanding motor circuits where strong current limitation and reliable fault interruption are essential.
As part of the established Mersen NH aM 690 V AC fuse-link range, the NH0AM69V160 allows normal motor starting currents to pass without unnecessary operation while rapidly interrupting severe short-circuit currents. Its robust construction, live gripping lugs and double indication system support straightforward installation, inspection and replacement within compatible NH fuse bases and switchgear.
With a rated current of 160 A, a rated voltage of 690 V AC and an NH0 fuse size, this fuse link is suitable for industrial motors, motor control centres, machinery and automation systems. As an aM fuse, it provides short-circuit protection and must be used together with a suitable overload protection device.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen NH0AM69V160 uses an aM operating characteristic developed specifically for motor circuit protection. Its time-current behaviour allows temporary motor starting currents while providing rapid interruption when a serious short-circuit fault occurs, helping protect motors, contactors, conductors and switchgear from damaging fault energy.
Because an aM fuse does not provide full-range overload protection, it must be coordinated with a suitable motor overload relay, circuit breaker or other protective device. This combination provides effective protection throughout normal operation, motor starting and fault conditions.
Typical Applications
- Industrial electric motors.
- Motor starters and contactor assemblies.
- Motor control centres.
- Manufacturing and processing machinery.
- Industrial automation systems.
- OEM control panels and electrical switchgear.
