Why Choose the Mersen NH1AM69V63P-2 63A 690V NH1 aM Fuse Link?

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.

Key Advantages

  • 63 A aM fuse characteristic designed for motor circuit short-circuit protection.
  • 690 V AC rated voltage for demanding industrial electrical systems.
  • Standard NH size 1 format for compatible NH fuse equipment.
  • Designed to tolerate normal motor starting and inrush currents when correctly selected.
  • Striker-equipped P-2 construction supports mechanical fuse-operation indication.
  • High-capacity NH construction for industrial motor control and power distribution applications.

Key Features

  • Mersen high-capacity NH fuse link.
  • 63 A rated current.
  • 690 V AC rated voltage.
  • aM utilisation category for motor circuit protection.
  • NH size 1 construction.
  • Striker-equipped fuse design.
  • Suitable for use with compatible NH fuse bases and fuse switch disconnectors.
  • Designed for industrial motor feeders and other high-inrush-load circuits.

Reliable Short-Circuit Protection for Motor Circuits

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.

Typical Applications

  • Industrial motor feeder short-circuit protection.
  • Motor control centres and electrical control panels.
  • Pumps, fans, compressors and conveyor motor circuits.
  • Industrial machinery with high motor starting currents.
  • Compatible NH fuse switch disconnectors and fuse bases.
  • 690 V AC low-voltage industrial distribution systems.
