Why Choose the Mersen NH1AM50V160 NH Fuse-Link?
The Mersen NH1AM50V160 is a high-performance DIN NH aM fuse-link designed to provide reliable short-circuit protection for motors, motor starters and associated industrial equipment. Part of Mersen's established NH aM 500 V AC fuse-link range, it is engineered for demanding motor circuits where dependable fault interruption and robust construction are essential.
This fuse-link has an aM operating characteristic, meaning it provides partial-range protection specifically intended for motor circuits. It protects against high short-circuit currents and should be used alongside a suitable overload relay or another dedicated overload protection device to provide complete motor protection.
With a 160 A current rating, 500 V AC rated voltage and NH1 body size, the NH1AM50V160 is suitable for motor control centres, industrial switchboards, machine control panels and OEM equipment. Its ceramic body, silver-plated copper blade contacts, double indicator and live gripping lugs support dependable operation and efficient maintenance.

Reliable Short-Circuit Protection for Motor Circuits
aM fuse-links are designed to interrupt high fault currents while allowing the temporary inrush currents associated with motor starting. This makes the Mersen NH1AM50V160 well suited to industrial motor circuits where standard full-range fuse-links may operate unnecessarily during normal starting conditions.
As an aM partial-range fuse-link, the NH1AM50V160 does not provide complete overload protection on its own. It should be coordinated with an appropriate motor overload relay, motor protection circuit breaker or equivalent protective device selected for the application.
Typical Applications
- Industrial motor control centres.
- Motor starters and contactor assemblies.
- Pumps, fans and compressor systems.
- Conveyors and material handling equipment.
- Industrial machinery and production equipment.
- OEM automation and machine-building applications.
