Why Choose the Mersen NH0AM50V100 NH Fuse Link?
The Mersen NH0AM50V100 is a high-performance DIN NH aM fuse link designed specifically for short-circuit protection in motor circuits and other industrial applications with high starting currents. As part of the dependable Mersen NH aM 500 V fuse range, it provides reliable protection for contactors, motor starters, cables and associated electrical equipment.
This NH fuse link features a robust ceramic body, blade contacts and live gripping lugs with a double indicator. The double indicator provides clear visual confirmation when the fuse has operated, helping maintenance personnel identify faults and restore equipment efficiently. Its standardised NH construction enables installation in a compatible NH0 fuse base.
With a rated current of 100 A, an operating voltage of 500 V AC and a high breaking capacity of up to 120 kA, the NH0AM50V100 is ideal for protecting industrial motors and control equipment against damaging short-circuit currents. As an aM partial-range fuse, it should be coordinated with a suitable overload protection device.

Reliable Short-Circuit Protection for Motor Circuits
Type aM fuse links are designed to protect motor circuits against high short-circuit currents while tolerating the temporary current surges produced when motors start. This characteristic helps prevent unnecessary fuse operation during normal acceleration while providing rapid disconnection when a serious electrical fault occurs.
Because an aM fuse provides partial-range protection, the Mersen NH0AM50V100 must be used with a correctly selected overload relay or another suitable overload protection device. Together, these components provide coordinated protection for motors, contactors, cables and motor-starting equipment.
Typical Applications
- Industrial motor protection circuits.
- Motor control centres and control panels.
- Direct-on-line and star-delta motor starters.
- Pumps, fans and compressor systems.
- Conveyors and materials-handling machinery.
- OEM production and processing equipment.
