Why Choose the Mersen NH000AM50V63 NH Fuse Link?
The Mersen NH000AM50V63 is a compact NH000 size aM fuse link designed to provide dependable short-circuit protection for motors, motor starters and industrial machinery. Rated at 63 A and 500 V AC, it is engineered for motor control circuits where high starting currents must be accommodated without nuisance fuse operation.
Its aM operating characteristic is specifically intended for motor circuit protection. The fuse tolerates temporary motor inrush currents while rapidly interrupting dangerous short-circuit currents. As an aM fuse provides partial-range protection, it must always be used alongside a suitable thermal overload relay or electronic motor protection device.
The NH000AM50V63 features a durable ceramic body, silver-plated blade contacts, live gripping tags and an integrated double indicator that provides clear visual confirmation when the fuse has operated. Its compact 21 mm body width makes it ideal for installation in compatible NH000 fuse bases and switch disconnectors used throughout industrial control systems.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen NH000AM50V63 protects industrial motors and associated equipment by rapidly interrupting high fault currents while allowing normal motor starting currents to pass. Its current-limiting design helps minimise thermal and mechanical stress on motors, cables, contactors and switchgear, improving the reliability of motor control systems.
As an aM fuse link, the NH000AM50V63 does not provide complete overload protection. It must be coordinated with a suitable overload relay or motor protection device. Installation and replacement should only be carried out by qualified personnel using approved NH fuse handling equipment and suitable personal protective equipment.
Typical Applications
- Industrial motor starters.
- Motor control centres.
- Pumps and compressors.
- Fans and ventilation systems.
- Conveyor and material handling equipment.
- Industrial machinery and automation systems.
