Why Choose the Mersen NH2AM69V35 Motor Protection Fuse-Link?
The Mersen NH2AM69V35 is a high-performance NH2 aM fuse-link designed specifically for the short-circuit protection of motors, motor starters and associated electrical equipment. Manufactured to the DIN NH standard, it provides strong current-limiting performance while tolerating the temporary inrush currents produced when industrial motors start.
Rated at 35 A and 690 V AC, the NH2AM69V35 is suitable for motor circuits operating within demanding industrial control and distribution systems. Its aM operating characteristic provides partial-range protection against short-circuit currents and must be combined with an appropriate overload relay or motor protection device.
The fuse-link features live gripping tags, a double visual indicator, silver-plated copper blade contacts and a robust ceramic body. With an 80 kA AC breaking capacity, it provides dependable interruption of high prospective fault currents within compatible NH2 fuse bases and fuse-switch disconnectors.

Reliable Short-Circuit Protection for Motor Circuits
Industrial motors can draw several times their normal operating current during starting. The aM characteristic of the Mersen NH2AM69V35 allows the fuse-link to tolerate these temporary starting currents while responding rapidly to damaging short-circuit conditions.
As an aM fuse-link provides short-circuit protection only, it must be used with a correctly selected overload relay, motor protection circuit breaker or equivalent protective device. Together, these components provide coordinated protection for motors, contactors, cables and associated control equipment.
Typical Applications
- Industrial motor starters.
- Motor control centres.
- Pump and fan control panels.
- Conveyor and material handling systems.
- Compressors and processing machinery.
- Industrial switchboards.
- OEM machine control panels.
- Manufacturing and automation systems.
