The Mersen NH1AM69V63P-2, manufacturer reference W226661, is a 63 A NH size 1 aM fuse link designed for motor circuit protection and other applications where short-circuit protection is required alongside a separate overload protection device. Its aM operating class is specifically intended for motor circuits and permits the temporary high inrush currents associated with motor starting.
Rated at 690 V AC, the NH1AM69V63P-2 uses the standard NH size 1 format for installation in compatible NH fuse bases and fuse switch disconnectors. The product is a high-capacity industrial fuse link intended for low-voltage power distribution and motor protection systems.
The P-2 configuration incorporates a striker, providing a mechanical indication or actuation facility when the fuse operates. This can be used with compatible equipment for fuse status indication or associated switching functions, depending on the design of the installation.
An aM fuse link is specifically intended for short-circuit protection of motor circuits. Unlike a full-range gG fuse, an aM fuse does not provide complete overload protection across the entire overcurrent range, so it is normally coordinated with a suitable motor overload relay or other dedicated overload protection device.
The Mersen NH1AM69V63P-2 combines a 63 A current rating, 690 V AC voltage rating and NH1 construction with a striker-equipped design. These characteristics make it suitable for industrial motor feeders where high starting currents must be accommodated while providing dependable protection against short-circuit faults.
