Why Choose the Mersen NH0AM69V35 NH Fuse-Link?
The Mersen NH0AM69V35 is a dependable DIN NH aM fuse-link designed to provide partial-range short-circuit protection for motors, motor starters and associated industrial equipment. As part of the established Mersen NH aM 690 V AC fuse-link range, it is engineered for motor circuits where overload protection is provided separately.
This NH0 fuse-link features a robust ceramic insulating body, double visual indicators and live gripping lugs. The indicators provide clear confirmation when the fuse-link has operated, while the standard blade terminals allow installation in compatible DIN NH fuse bases and fuse-switch equipment.
With a rated current of 35 A, a rated operating voltage of 690 V AC and an AC breaking capacity of 80 kA, the NH0AM69V35 provides reliable protection against damaging short-circuit currents. Its aM characteristic accommodates normal motor starting currents while rapidly interrupting severe electrical faults.

Reliable Protection for Industrial Motor Circuits
The Mersen NH0AM69V35 is designed to tolerate the temporary inrush currents associated with motor starting while providing rapid interruption of dangerous short-circuit currents. This helps protect contactors, cables, starters and connected motor equipment from severe electrical damage.
As an aM partial-range fuse-link, it does not provide complete overload protection. It should therefore be coordinated with a suitable overload relay, motor protection circuit breaker or electronic motor protection device selected for the installation.
Typical Applications
- Industrial motor starter circuits.
- Motor control centres.
- Variable speed drive installations.
- Pumps, fans and compressor systems.
- OEM machinery and automation equipment.
- Industrial switchboards and control panels.
