Why Choose the Mersen NH1AM69V160 Motor Protection Fuse-Link?
The Mersen NH1AM69V160 is a dependable DIN NH aM low-voltage fuse-link designed specifically for short-circuit protection in industrial motor circuits. Rated at 160 A and 690 V AC, this NH Size 1 fuse-link helps protect motors, contactors, starters, cables and associated control equipment against damaging high fault currents.
As an aM partial-range fuse-link, the NH1AM69V160 provides strong current-limiting performance with low power losses. It is intended to interrupt short-circuit currents while allowing the temporary starting currents associated with electric motors. A suitable overload relay or other overload protection device must therefore be installed alongside the fuse-link to provide complete motor circuit protection.
The fuse-link features live gripping lugs and a double indicator for convenient handling and rapid identification after operation. Its standardised NH1 construction allows installation in compatible NH fuse bases and switch-fuse disconnectors used in motor control centres, industrial machinery and electrical distribution panels.
Key Advantages
- Designed specifically for industrial motor short-circuit protection.
- 160 A rated current for demanding motor circuits.
- 690 V AC voltage rating suitable for industrial power systems.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen NH1AM69V160 is engineered to limit the high electrical and mechanical stresses produced during short-circuit conditions. Its fast current-limiting action helps reduce the energy allowed through to motor starters, contactors, cables and other components within the protected circuit.
Because an aM fuse-link provides partial-range protection, it does not protect the motor against sustained overload currents. The fuse-link must be coordinated with a correctly selected thermal or electronic overload relay to provide effective protection across the complete motor operating range.
Typical Applications
- Industrial motor control centres.
- Direct-on-line motor starters.
- Star-delta starter circuits.
- Pumps, fans and compressor systems.
- Manufacturing and processing machinery.
- Industrial automation and control panels.
