Why Choose the Mersen NH0AM69V63 Motor Protection Fuse Link?
The Mersen NH0AM69V63 is a compact and reliable DIN NH aM fuse link designed to provide short-circuit protection for motor circuits and associated industrial electrical equipment. Manufactured by Mersen, this NH0 fuse link accommodates the temporary high inrush currents produced during motor starting while responding rapidly to damaging short-circuit conditions.
As part of the Mersen NH aM 690 V AC fuse range, the NH0AM69V63 offers strong current-limiting performance with low power losses. Its durable ceramic body, silver-plated copper blade terminals and live gripping lugs provide dependable electrical and mechanical performance in motor control centres, industrial panels and machinery installations.
With a rated current of 63 A, a 690 V AC voltage rating and an 80 kA breaking capacity, the NH0AM69V63 is suitable for demanding motor applications where effective fault interruption is required. Its double indication system also helps maintenance personnel identify an operated fuse quickly.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen NH0AM69V63 uses an aM operating characteristic developed for motor circuit protection. It allows normal motor acceleration and starting currents to pass without unnecessary fuse operation while interrupting severe fault currents that could damage motors, contactors, cables and switchgear.
As an aM partial-range fuse link, the NH0AM69V63 provides short-circuit protection only and must be combined with a suitable overload relay or motor protection device. Installation and replacement should be undertaken by qualified electrical personnel using the correct NH fuse-handling equipment.
Typical Applications
- Industrial motor control centres.
- Electric motor short-circuit protection.
- Pumps, fans and compressor systems.
- Industrial machinery and production equipment.
- OEM automation and control panels.
- Switchboards operating at up to 690 V AC.
