Why Choose the Mersen NH2AM69V200 Motor Protection Fuse Link?
The Mersen NH2AM69V200 is a high-performance DIN NH aM fuse link designed to provide dependable short-circuit protection for motor circuits and associated industrial electrical equipment. Manufactured by Mersen, this NH2 fuse link accommodates the high inrush currents generated during motor starting while rapidly interrupting damaging short-circuit currents.
As part of the established Mersen NH aM 690 V AC fuse range, the NH2AM69V200 combines strong current-limiting performance with low power losses. Its durable ceramic body, silver-plated copper blade terminals, live gripping lugs and double indication system support reliable operation and straightforward maintenance in demanding industrial environments.
With a rated current of 200 A, a 690 V AC voltage rating and an 80 kA breaking capacity, the NH2AM69V200 is suitable for motor control centres, industrial switchboards and machinery installations. Its NH2 format enables installation in compatible NH fuse bases as part of a coordinated motor protection system.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen NH2AM69V200 uses an aM operating characteristic developed specifically for motor circuit protection. It permits normal motor starting and acceleration currents without unnecessary fuse operation while interrupting severe short-circuit currents that could damage motors, contactors, cables and switchgear.
As an aM partial-range fuse link, the NH2AM69V200 provides short-circuit protection rather than overload protection. It must therefore be combined with a suitable thermal overload relay, motor protection circuit breaker or equivalent protective device. Installation and replacement should be undertaken by qualified electrical personnel using appropriate NH fuse-handling equipment.
Typical Applications
- Industrial motor control centres.
- Electric motor short-circuit protection.
- Pumps, fans and compressor systems.
- Industrial machinery and production equipment.
- OEM automation and control panels.
- Switchboards operating at up to 690 V AC.
