Why Choose the Mersen NH000AM50V40 Motor Protection Fuse Link?
The Mersen NH000AM50V40 is a compact DIN NH aM fuse link engineered to provide dependable short-circuit protection for motor circuits and industrial electrical equipment. Manufactured by Mersen, this NH000 fuse link is designed to withstand the high inrush currents generated during motor starting while rapidly interrupting damaging fault currents, helping to protect motors and associated control equipment.
Part of the trusted Mersen NH aM 500 V AC fuse series, the NH000AM50V40 features live gripping lugs and a double indication system, allowing quick identification of an operated fuse and safer replacement using an approved NH fuse puller. Its ceramic body and silver-plated copper blade terminals provide excellent durability and dependable electrical performance in demanding industrial environments.
With a 40 A rated current, a 500 V AC operating voltage and an 80 kA AC breaking capacity, the NH000AM50V40 is ideal for motor control centres, industrial switchboards, machinery and OEM control panels requiring reliable motor short-circuit protection.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen NH000AM50V40 incorporates an aM operating characteristic specifically developed for motor applications. It permits normal motor starting currents without nuisance operation while providing rapid interruption of damaging short-circuit faults. As with all aM fuse links, it should be used alongside an appropriate thermal overload relay or motor protection device.
Its current-limiting design helps reduce thermal and electrodynamic stress throughout the electrical installation, protecting motors, contactors, cables and switchgear while helping minimise equipment damage and downtime.
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.
