Why Choose the Mersen NH000AM50V4 Motor Protection Fuse-Link?
The Mersen NH000AM50V4 is a high-performance NH000 aM fuse-link designed specifically for the short-circuit protection of motors, motor starters and associated electrical equipment. Manufactured to the DIN NH standard, it provides excellent current-limiting performance whilst safely withstanding the high inrush currents generated during motor starting.
Rated at 4 A with a 500 V AC operating voltage, the NH000AM50V4 forms part of Mersen's proven aM motor protection fuse range. The aM operating characteristic provides short-circuit protection only and should always be used alongside an appropriately selected overload relay or motor protection device to provide complete motor protection.
Featuring live gripping tags, a double visual indicator, silver-plated copper blade contacts and a durable ceramic body, the NH000AM50V4 delivers dependable protection for motor control panels, OEM machinery and industrial electrical installations.

Reliable Short-Circuit Protection for Motor Circuits
The NH000AM50V4 is designed for motor circuits where temporary starting currents occur. Its aM characteristic allows the fuse-link to tolerate these inrush currents whilst providing rapid interruption during short-circuit faults, helping protect motors, starters and associated control equipment.
As an aM fuse-link provides short-circuit protection only, it should always be combined with a correctly selected overload relay or motor protection device to provide complete protection for the motor installation.
Typical Applications
- Motor starters.
- Motor control centres.
- Industrial motor circuits.
- Pump and fan control panels.
- OEM machinery.
- Industrial switchboards.
- HVAC equipment.
- Manufacturing automation systems.
