Why Choose the Mersen NH1AM50V200 NH Fuse-Link?
The Mersen NH1AM50V200 is a robust DIN NH aM fuse-link designed to provide reliable short-circuit protection for motors, motor starters and industrial power circuits. Manufactured by Mersen, this NH1 fuse-link is intended for use alongside suitable overload protection in demanding motor-control and machinery applications.
Part of the established Mersen NH aM 500 V AC fuse-link series, the NH1AM50V200 has a rated current of 200 A and a rated operating voltage of 500 V AC. Its aM utilisation category is specifically suited to motor circuits, where the fuse-link must withstand normal motor starting currents whilst providing rapid protection against damaging short-circuit faults.
The NH1AM50V200 features live gripping lugs, a double indicator and a standard NH blade-contact format. Its 40 mm body width allows installation in compatible NH1 fuse bases within motor control centres, industrial switchboards and electrical distribution equipment.

Reliable Protection for Industrial Motor Circuits
The Mersen NH1AM50V200 is designed to protect motor circuits against short-circuit currents while tolerating the temporary current surges that occur when industrial motors start. This makes it suitable for use with contactors, motor starters and coordinated overload protection devices.
As an aM fuse-link, the NH1AM50V200 does not provide full-range overload protection on its own. It should be coordinated with a correctly selected motor overload relay, motor protection circuit breaker or equivalent protective device to provide complete motor circuit protection.
Typical Applications
- Industrial motor control centres.
- Direct-on-line and star-delta motor starters.
- Pumps, fans and compressor systems.
- Conveyors and material-handling machinery.
- Industrial switchboards and control panels.
- OEM machinery and automated production equipment.
