Why Choose the Mersen NH000AM50V80 NH Fuse-Link?
The Mersen NH000AM50V80 is a compact DIN NH aM fuse-link designed to provide dependable short-circuit protection for motors, motor starters and associated industrial electrical equipment. Part of the established Mersen NH motor protection range, it is engineered to withstand normal motor starting currents while responding effectively to damaging short-circuit faults.
This fuse-link combines the space-efficient NH000 format with a durable ceramic body, silver-plated copper blade contacts and live gripping lugs. Its integrated double indication system provides clear visual confirmation after operation, helping maintenance teams identify faults quickly and reduce machinery downtime.
With a rated current of 80 A, a rated voltage of 500 V AC and a high 120 kA breaking capacity, the NH000AM50V80 is suitable for motor control centres, industrial machinery and OEM control panels requiring reliable partial-range aM protection.

- Specialist aM protection for motor circuits.
- 80 A rated current for industrial motor applications.
- 500 V AC rated voltage.
- 120 kA AC breaking capacity for dependable fault interruption.
- Double indicator enables quick visual identification after operation.
- Compact NH000 construction helps conserve valuable panel space.
Key Features
- Mersen NH aM 500 V fuse-link series.
- 80 A rated current.
- 500 V AC rated voltage.
- NH000 DIN fuse size.
- Partial-range aM motor protection characteristic.
- Integrated double indication system.
- Live gripping lugs.
- Silver-plated copper plain blade contacts.

Reliable Short-Circuit Protection for Motor Circuits
The aM operating characteristic is specifically intended for motor circuit protection. It allows the temporary inrush current associated with motor starting to pass without unnecessary operation while providing rapid protection against high short-circuit currents.
As an aM partial-range fuse-link, the Mersen NH000AM50V80 does not provide overload protection on its own. It should be installed with a correctly selected overload relay or motor protection device to provide complete protection for the motor and associated circuit.
Typical Applications
- Industrial motor control centres.
- Direct-on-line and reversing motor starters.
- Industrial pumps, fans and compressors.
- Manufacturing and processing machinery.
- OEM electrical control panels.
- Commercial and industrial motor circuits.
