Why Choose the Mersen NH00AM50V160 NH Fuse-Link?
The Mersen NH00AM50V160 is a high-performance DIN NH size 00 aM fuse-link designed specifically for short-circuit protection in motor circuits and other high-inrush industrial loads. Rated at 160 A and 500 V AC, it is suitable for motor control centres, industrial machinery, pump systems and electrical distribution equipment.
Its aM operating characteristic is engineered to tolerate the temporary starting currents produced by electric motors while responding rapidly to high short-circuit currents. As an aM partial-range fuse-link, it must be used alongside a suitable overload protection device, such as a motor protection relay or thermal overload relay.
The NH00AM50V160 features a durable ceramic body, silver-plated copper blade contacts, live gripping lugs and a double indication system. These features provide reliable current interruption, straightforward status identification and compatibility with standard NH size 00 fuse bases and fuse-switch disconnectors.

Reliable Protection for Motor Circuits
Electric motors can draw several times their normal operating current during start-up. The aM characteristic allows the NH00AM50V160 to withstand these temporary inrush currents without unnecessary operation while still providing rapid protection against severe short-circuit faults.
Because an aM fuse-link provides partial-range protection, it does not independently protect a motor against sustained overloads. It must therefore be coordinated with a suitable overload relay or motor protection device selected for the motor and application.
Typical Applications
- Industrial motor control centres.
- Three-phase motor feeder circuits.
- Pumps, fans and compressor systems.
- Conveyors and materials handling equipment.
- Industrial machinery and production lines.
- NH fuse bases and fuse-switch disconnectors.
