Why Choose the Mersen NH000AM69V20 Motor Protection Fuse Link?
The Mersen NH000AM69V20 is a compact DIN NH aM fuse link designed to provide reliable short-circuit protection for motor circuits and industrial electrical equipment. Manufactured by Mersen, this NH000 fuse link is engineered to withstand the high inrush currents generated during motor starting while rapidly clearing high fault currents to protect valuable equipment.
As part of the trusted Mersen NH aM 690 V AC fuse range, the NH000AM69V20 features live gripping lugs and a double indication system, allowing quick identification of an operated fuse and safer replacement using an appropriate NH fuse puller. Its robust ceramic body and silver-plated copper blade terminals provide excellent durability and electrical performance in demanding industrial environments.
With a 20 A rated current, a 690 V AC operating voltage and an 80 kA breaking capacity, the NH000AM69V20 is ideally suited for motor control centres, machinery, industrial switchboards and OEM control panels where dependable motor circuit protection is essential.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen NH000AM69V20 incorporates an aM operating characteristic specifically developed for motor applications. It allows the high starting currents of electric motors to pass without nuisance operation while providing rapid interruption of damaging short-circuit faults. As with all aM fuse links, overload protection should be provided by a suitable thermal overload relay or motor protection device.
Its current-limiting design helps reduce thermal and mechanical stress on motors, contactors, cables and switchgear, improving equipment protection and reducing downtime following electrical faults.
Typical Applications
- Motor control centres (MCCs).
- Industrial motor protection.
- OEM machinery and automation systems.
- Industrial switchboards.
- Pumps, fans and compressors.
- Manufacturing and process control equipment.
