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.
Key Advantages
- Purpose-designed for motor circuit short-circuit protection.
- 160 A rated current for demanding industrial loads.
- 500 V AC rated voltage.
- aM characteristic tolerates normal motor starting currents.
- High 120 kA AC breaking capacity.
- Double indicator assists with rapid fuse status identification.
- Compact NH size 00 format for compatible fusegear.
Key Features
- Mersen DIN NH aM fuse-link.
- Catalogue number: NH00AM50V160.
- Manufacturer item number: J227869.
- Fuse size: NH00.
- Rated current: 160 A.
- Rated voltage: 500 V AC.
- Utilisation category: aM.
- Integrated double indication system.
- Live gripping lugs.
- Silver-plated copper plain blade contacts.
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.

Frequently Asked Questions
What is the Mersen NH00AM50V160 used for?
It is used to provide short-circuit protection for motor circuits and other industrial loads with high starting or inrush currents.
What is the rated current of this fuse-link?
The NH00AM50V160 has a rated current of 160 A.
What does the aM utilisation category mean?
The aM classification identifies a partial-range motor circuit fuse-link designed primarily for short-circuit protection while tolerating normal motor starting currents.
Does this fuse-link provide overload protection?
No. An aM fuse-link must be used with a separate overload protection device, such as a thermal overload relay or electronic motor protection relay.
Where is the NH00AM50V160 installed?
It is installed in a compatible NH size 00 fuse base or fuse-switch disconnector and should only be handled by qualified electrical personnel using approved equipment.
