Why Choose the Mersen NH2GG50V315-1 NH Fuse Link?

The Mersen NH2GG50V315-1 is a high-performance NH2 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 delivers dependable protection against overload currents and short circuits in demanding electrical distribution systems.

Part of Mersen's established NH fuse-link range, the NH2GG50V315-1 features a durable ceramic body, brass blade contacts, isolated gripping lugs and a double indication system. The isolated tags support safer handling by qualified personnel, while the dual indicator allows an operated fuse to be identified quickly during inspection and maintenance.

With a rated current of 315 A, an operating voltage of up to 500 V AC and a 250 V DC rating, this fuse link is suitable for high-current distribution boards, switchgear and industrial machinery. Its 120 kA AC breaking capacity enables reliable interruption of substantial prospective fault currents.

Key Advantages

  • Industrial NH2 gG fuse link for full-range cable and line protection.
  • 315 A rated current for high-current electrical installations.
  • 500 V AC and 250 V DC voltage ratings.
  • High 120 kA AC breaking capacity for dependable fault interruption.
  • Double indicator enables rapid identification after fuse operation.
  • Isolated gripping lugs support safer professional handling and replacement.

Key Features

  • Mersen NH gG fuse-link series.
  • 315 A rated current.
  • 500 V AC rated voltage.
  • 250 V DC rated voltage.
  • gG full-range operating characteristic.
  • NH2 standard fuse size.
  • 120 kA AC interrupting capacity.
  • Double fuse-operation indication system.
  • Isolated gripping lugs.
  • Ceramic body with brass blade contacts.

Reliable High-Current Circuit Protection

The Mersen NH2GG50V315-1 uses a gG operating characteristic to provide comprehensive protection against overloads and short circuits. When an unsafe current occurs, the fuse element interrupts the electrical supply before excessive heat or fault energy can seriously damage cables, switchgear or connected equipment.

Its NH2 blade-contact format is intended for installation in a compatible NH fuse base or fused switch-disconnector. The ceramic construction provides excellent electrical insulation and thermal resistance, while the isolated gripping lugs and double indicator support efficient maintenance in industrial environments.

Typical Applications

  • Industrial low-voltage distribution boards.
  • High-current electrical switchgear.
  • Cable and conductor protection.
  • Motor control centres.
  • Industrial machinery power circuits.
  • Commercial and manufacturing facilities.
  • NH fuse bases and fused switch-disconnectors.
