Why Choose the Mersen NH000AM50V25 NH Fuse Link?
The Mersen NH000AM50V25 is a high-quality NH aM low voltage fuse link designed specifically for the short-circuit protection of motor circuits and industrial electrical equipment. As part of the trusted Mersen NH aM fuse-link series, it provides dependable fault protection for motors, starters and associated switchgear operating in demanding industrial environments.
Featuring a 25 A rated current and a 500 V AC rating, this NH000 fuse link offers high breaking capacity while maintaining low power dissipation. The integrated double indicator provides fast visual identification after operation, while the live gripping lugs enable safer installation and replacement using an approved NH fuse puller.
Unlike gG fuse links, the aM operating characteristic is designed specifically for motor circuit protection against short circuits and must be used alongside an appropriate overload protection device. Its compact NH000 format makes it ideal for motor control centres, industrial switchboards and OEM machinery.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen NH000AM50V25 is designed to protect electric motors and associated equipment against damaging short-circuit currents. Its aM characteristic allows motors to withstand normal starting currents while providing rapid interruption under fault conditions. Because aM fuse links protect only against short circuits, they must always be used together with an appropriate overload relay or motor protection device.
Its compact NH000 design, ceramic construction and high interrupting capacity make it suitable for industrial control panels, motor starters, distribution equipment and OEM machinery requiring reliable motor circuit protection.
Typical Applications
- Motor control centres.
- Industrial motor starters.
- Electrical switchboards.
- OEM machinery.
- Industrial automation systems.
- Protection of AC motor circuits.
