Why Choose the Mersen NH2AM69V224 NH Fuse-Link?
The Mersen NH2AM69V224 is a high-performance NH aM low voltage fuse-link specifically engineered to provide reliable short-circuit protection for industrial motor circuits. Designed in accordance with DIN NH standards, this fuse-link protects motors, motor starters and associated equipment while allowing the temporary inrush currents generated during motor starting without unnecessary fuse operation.
As part of the proven Mersen NH aM 690 VAC fuse-link series, the NH2AM69V224 combines a robust ceramic body with excellent current-limiting characteristics and a high fault interruption capability. Its double indicator enables rapid visual identification following operation, while the live gripping tags allow safer installation and replacement using an approved NH fuse puller.
Rated at 224 A with a 690 V AC operating voltage, the NH2AM69V224 is ideal for industrial motor control centres, pumps, compressors, conveyors, production machinery and OEM equipment where dedicated overload protection is provided separately.

Reliable Protection for Industrial Motor Circuits
The Mersen NH2AM69V224 is designed specifically for protecting motor circuits against high fault currents. Its aM operating characteristic allows motors to start normally while rapidly interrupting damaging short-circuit faults. Since aM fuse-links provide only partial-range protection, they should always be used with a suitable motor overload relay or electronic motor protection device.
Its high current-limiting performance helps reduce thermal and mechanical stress on motors, cables and switching equipment during fault conditions. The standard NH2 design ensures compatibility with suitable NH fuse bases and switch-disconnectors used throughout industrial electrical installations.
Typical Applications
- Industrial motor control centres.
- Motor starters and contactor assemblies.
- Pumps and pumping systems.
- Compressors and process equipment.
- Conveyors and material handling systems.
- OEM machinery and automation equipment.
- Industrial switchgear and control panels.
