Why Choose the Mersen NH00GG50V63-1 NH Fuse Link?

The Mersen NH00GG50V63-1 is a reliable NH00 gG fuse link designed to provide full-range protection for electrical cables, conductors and low-voltage industrial equipment. Manufactured to the DIN NH format, it safely interrupts overload currents and short circuits in demanding electrical distribution applications.

Part of Mersen's established NH fuse-link range, the NH00GG50V63-1 features a robust ceramic body, blade contacts, isolated gripping lugs and a double indication system. The isolated gripping lugs support safer handling by qualified personnel, while the dual indicator helps maintenance teams identify an operated fuse quickly.

With a rated current of 63 A, a rated operating voltage of 500 V AC and a 250 V DC rating, this fuse link is suitable for distribution boards, industrial switchgear, control panels and machinery circuits. Its compact NH00 construction enables installation in compatible NH fuse bases and fused switch-disconnectors.

Key Advantages

  • Industrial NH00 gG fuse link for full-range circuit protection.
  • 63 A rated current for low-voltage electrical installations.
  • 500 V AC and 250 V DC voltage ratings.
  • Protects cables and equipment against overloads and short circuits.
  • Double indicator allows rapid identification after fuse operation.
  • Isolated gripping lugs support safer professional handling and replacement.

Key Features

  • Mersen NH gG fuse-link series.
  • 63 A rated current.
  • 500 V AC rated voltage.
  • 250 V DC rated voltage.
  • gG full-range operating characteristic.
  • NH00 fuse size.
  • Double fuse-operation indication system.
  • Isolated metal gripping lugs.
  • Durable ceramic insulating body.
  • DIN-format blade-contact construction.

Reliable Protection for Low-Voltage Distribution

The Mersen NH00GG50V63-1 uses a gG operating characteristic to provide full-range protection against overload currents and short circuits. When current exceeds safe operating limits, the fuse element interrupts the circuit before excessive heat or fault energy can seriously damage cables, switchgear or connected equipment.

Its NH00 blade-contact construction is designed for use with a compatible NH fuse base or fused switch-disconnector. The ceramic body provides effective electrical insulation and thermal resistance, while the isolated gripping lugs and double indicator support efficient maintenance in industrial installations.

Typical Applications

  • Industrial low-voltage distribution boards.
  • Electrical switchgear and control panels.
  • Cable and conductor protection.
  • Industrial machinery power circuits.
  • Commercial electrical installations.
  • OEM equipment and automation systems.
  • NH fuse bases and fused switch-disconnectors.
