Why Choose the Mersen NH2AM69V160 Motor Fuse Link?
The Mersen NH2AM69V160 is a high-performance DIN NH aM fuse link designed specifically for short-circuit protection in industrial motor circuits. Manufactured by Mersen, this NH Size 2 fuse link provides strong current-limiting performance and low power losses, helping protect motors, contactors, motor starters and associated electrical equipment against damaging fault currents.
Featuring a rated current of 160 A and a rated operating voltage of 690 V AC, the NH2AM69V160 is designed to tolerate the temporary inrush currents associated with motor starting while rapidly interrupting severe short-circuit currents. Its partial-range aM operating class makes it suitable for coordinated motor protection systems incorporating a separate overload protection device.
Manufactured in the standard NH Size 2 format, this fuse link features blade contacts, live gripping lugs, a double operation indicator and a body width of approximately 52 mm. Its durable construction and compliance with recognised international standards make it suitable for demanding industrial motor control and power distribution applications.

Reliable Short-Circuit Protection for Motor Circuits
Industrial motors can draw several times their normal operating current during start-up. The Mersen NH2AM69V160 is designed to accommodate these temporary starting currents while interrupting dangerous short-circuit currents before they cause extensive damage to motors, starters, conductors or switching equipment.
As an aM partial-range fuse, the NH2AM69V160 provides short-circuit protection rather than complete overload protection. It must therefore be coordinated with a suitable overload relay, motor protection circuit breaker or equivalent device to provide comprehensive motor circuit protection.
Typical Applications
- Industrial motor starter circuits.
- Motor control centres.
- Pumps, fans and compressor systems.
- Conveyors and material handling equipment.
- Manufacturing and processing machinery.
- Industrial switchboards and control panels.
