Why Choose the Mersen NH00GG50V50-1 NH Fuse Link?

The Mersen NH00GG50V50-1 is a reliable NH00 gG fuse link designed to provide full-range protection for industrial cables, conductors, switchgear and electrical equipment. Manufactured for low-voltage power distribution applications, this DIN-style fuse link provides effective protection against both sustained overloads and high short-circuit currents.

Featuring a gG operating characteristic, the NH00GG50V50-1 is suitable for general-purpose cable and equipment protection across the complete fault-current range. Its current-limiting performance helps reduce the thermal and electrodynamic energy transferred to cables, busbars and connected components during an electrical fault.

With a rated current of 50 A, an AC voltage rating of 500 V and a DC voltage rating of 250 V, this fuse link is suitable for industrial distribution boards, control panels and machinery circuits. Its double indication system supports rapid identification of fuse operation, while the isolated gripping lugs improve handling safety during professional installation and replacement.

Key Advantages

  • Full-range gG protection against overloads and short circuits.
  • 50 A rated current for industrial electrical circuits.
  • Suitable for systems rated up to 500 V AC and 250 V DC.
  • High 120 kA AC breaking capacity for dependable fault interruption.
  • Double indication system supports rapid identification of an operated fuse.
  • Isolated gripping lugs improve handling safety during fuse replacement.

Key Features

  • Mersen NH gG low-voltage fuse-link range.
  • 50 A ampere rating.
  • 500 V AC rated voltage.
  • 250 V DC rated voltage.
  • NH00 DIN fuse format.
  • gG full-range operating characteristic.
  • Integrated double fuse-operation indicator.
  • Isolated gripping lugs.
  • Plain blade terminals.
  • Robust ceramic insulating body.

Reliable Protection for Industrial Electrical Systems

The Mersen NH00GG50V50-1 disconnects the electrical supply when an overload or short-circuit current exceeds the fuse’s operating limits. Its current-limiting action helps reduce damaging thermal energy and mechanical forces before they reach cables, switchgear and connected electrical equipment.

As a gG full-range fuse link, this model provides protection against both overload currents and severe short-circuit faults. It can therefore be used as the primary fuse in appropriately designed general-purpose distribution circuits. Installation and replacement should only be completed by qualified electrical personnel using a compatible NH fuse base and approved fuse-handling equipment.

Typical Applications

  • Industrial power distribution boards.
  • Low-voltage switchgear assemblies.
  • Cable and conductor protection.
  • Electrical control panels and cabinets.
  • Industrial machinery supply circuits.
  • Commercial and manufacturing electrical installations.
