Why Choose the Mersen NH0AM69V100 NH Fuse Link?

The Mersen NH0AM69V100 is a robust NH0 size aM fuse link designed to provide dependable short-circuit protection for motors, motor starters and industrial electrical equipment. Rated at 100 A and 690 V AC, it is specifically engineered for motor circuits where high starting currents must be tolerated without unnecessary fuse operation.

Its aM operating characteristic is intended exclusively for motor circuit protection. The fuse withstands the temporary inrush currents generated during motor start-up while rapidly interrupting dangerous short-circuit currents. Because an aM fuse provides partial-range protection, it should always be used alongside a correctly selected overload relay or other suitable overload protection device.

The NH0AM69V100 features a durable ceramic body, silver-plated blade contacts, live gripping tags and an integrated double indicator for quick identification of an operated fuse. Its compact NH0 format with a 30 mm body width enables straightforward installation in compatible NH fuse bases and switch disconnectors.

Key Advantages

  • Purpose-designed aM short-circuit protection for motor circuits.
  • 100 A rated current for industrial motors and machinery.
  • 690 V AC operating voltage.
  • Current-limiting design helps reduce fault energy.
  • Compact NH0 construction for efficient panel installation.
  • Double indicator supports rapid identification of an operated fuse.

Key Features

  • Mersen NH aM industrial fuse-link range.
  • NH0 standard fuse size.
  • 100 A rated current.
  • 690 V AC rated voltage.
  • aM partial-range motor protection characteristic.
  • Integrated double fuse indicator.
  • Live gripping tags for safe handling.
  • Silver-plated blade contacts.
  • Robust ceramic insulating body.
  • 30 mm body width.

Reliable Short-Circuit Protection for Motor Circuits

The Mersen NH0AM69V100 is designed to protect industrial motors and associated equipment by rapidly interrupting high fault currents while allowing normal motor starting currents to pass. Its current-limiting performance helps reduce thermal and mechanical stress on motors, contactors, cables and switchgear.

As an aM fuse link, the NH0AM69V100 does not provide complete overload protection. It must be used with an appropriately selected thermal or electronic overload relay. Installation and replacement should only be carried out by qualified personnel using approved NH fuse handling equipment.

Typical Applications

  • Industrial motor starters.
  • Motor control centres.
  • Pumps and compressors.
  • Fans and ventilation systems.
  • Conveyor and material handling equipment.
  • Industrial machinery and automation systems.
