Why Choose the Mersen NH1AM50V224 NH Fuse-Link?
The Mersen NH1AM50V224 is a high-performance DIN NH aM low voltage 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 engineered for applications where high motor starting currents must be tolerated without unnecessary fuse operation.
Part of the proven Mersen NH aM 500 V AC fuse-link series, the NH1AM50V224 has a rated current of 224 A, a rated operating voltage of 500 V AC and an AC breaking capacity of 120 kA. Its partial-range aM characteristic provides effective short-circuit protection whilst allowing normal motor starting currents to pass.
The fuse-link incorporates a double indicator, live gripping lugs and standard NH blade contacts. Its robust NH1 construction and 40 mm body width make it suitable for compatible fuse bases installed within motor control centres, industrial switchboards and machinery control panels.

Reliable Protection for Industrial Motor Circuits
The Mersen NH1AM50V224 is engineered to protect motors and motor feeders against damaging short-circuit currents. Its aM operating characteristic allows it to tolerate the temporary current peaks generated when industrial motors start, whilst providing rapid fault interruption when a serious short circuit occurs.
As an aM partial-range fuse-link, the NH1AM50V224 does not provide overload protection independently. It must be coordinated with a correctly selected 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 motor starters.
- Star-delta motor starter assemblies.
- Pumps, fans and compressor systems.
- Conveyors and material-handling equipment.
- OEM machinery and automated production systems.
