Why Choose the Mersen NH1GG50V20 NH Fuse-Link?

The Mersen NH1GG50V20 is a dependable DIN NH gG fuse-link designed to provide full-range overload and short-circuit protection for cables, conductors and general-purpose low-voltage electrical circuits. Part of the established Mersen NH fuse-link range, it offers reliable protection for industrial switchgear, distribution boards and electrical equipment.

This fuse-link combines an NH1 body size with a robust ceramic construction, plain blade terminals and live gripping lugs. Its integrated double indicator provides clear visual confirmation when the fuse has operated, helping simplify fault identification and routine maintenance.

With a rated current of 20 A, an AC voltage rating of 500 V and a DC voltage rating of 250 V, the NH1GG50V20 is suitable for a wide range of industrial and commercial power distribution applications requiring dependable gG protection.

Key Advantages

  • Full-range gG protection against overloads and short circuits.
  • 20 A rated current for low-voltage distribution circuits.
  • 500 V AC and 250 V DC voltage ratings.
  • 120 kA AC breaking capacity for reliable fault interruption.
  • Double indicator enables quick visual identification after operation.
  • Live gripping lugs support controlled handling with an approved NH fuse puller.

Key Features

  • Mersen NH gG 500 V fuse-link series.
  • 20 A rated current.
  • 500 V AC rated voltage.
  • 250 V DC rated voltage.
  • NH1 DIN fuse size.
  • Full-range gG operating characteristic.
  • Integrated double indication system.
  • Live gripping lugs.
  • Plain brass blade terminals.
  • Durable ceramic insulating body.

Reliable Full-Range Circuit Protection

The gG operating characteristic allows the Mersen NH1GG50V20 to provide protection against both sustained overload currents and high-level short circuits. This makes it suitable for protecting cables, conductors and general electrical distribution equipment throughout low-voltage installations.

Its high breaking capacity enables the fuse-link to interrupt substantial prospective fault currents safely. The fuse must be installed and replaced by qualified electrical personnel using a compatible DIN NH fuse base, an approved fuse puller and appropriate isolation procedures.

Typical Applications

  • Industrial power distribution boards.
  • Electrical switchgear and control panels.
  • Cable and conductor protection.
  • Machinery power supply circuits.
