Why Choose the Mersen NH2AM69V224P-2 NH Motor Fuse Link?
The Mersen NH2AM69V224P-2 is a high-performance NH aM low-voltage HRC fuse link designed specifically for short-circuit protection in industrial motor circuits. Its current-limiting performance helps protect motor starters, contactors, cables and associated equipment against damaging fault currents in demanding electrical installations.
Part of the specialist Mersen NH aM fuse-link range, the NH2AM69V224P-2 features live gripping lugs and an integrated mechanical striker. The striker provides a clear indication when the fuse has operated and can interact with compatible microswitch accessories to support remote fault signalling or switchgear tripping.
With a 224 A rated current, a 690 V AC voltage rating and an NH Size 2 format, this fuse link is suitable for protecting high-power motor circuits and industrial machinery. As an aM partial-range fuse, it provides short-circuit protection and must be used alongside a suitable overload protection device.

Reliable Short-Circuit Protection for Industrial Motors
Type aM fuse links are partial-range devices developed specifically for motor circuits. Their strong current-limiting characteristics allow them to interrupt high short-circuit currents rapidly while accommodating the temporary inrush currents associated with motor starting.
The Mersen NH2AM69V224P-2 does not provide full overload protection. It must therefore be coordinated with a suitable motor overload relay, circuit breaker or other protective device that protects the motor against sustained overload conditions.
Typical Applications
- Industrial motor control centres.
- Motor starters and contactor assemblies.
- Pumps, fans and compressor systems.
- Conveyors and materials-handling machinery.
- Manufacturing and processing equipment.
- Compatible NH2 fuse bases and fuse switch disconnectors.
