Why Choose the Mersen NH00GG50V100 NH Fuse-Link?

The Mersen NH00GG50V100 is a premium NH size 00 gG fuse-link designed to provide full-range protection against overloads and short circuits in industrial electrical installations. Rated at 100 A and 500 V AC, it is ideal for protecting cables, conductors, switchgear and power distribution equipment in commercial and industrial applications.

Its gG utilisation category delivers comprehensive protection throughout the entire operating range. The NH00GG50V100 responds to both sustained overloads and severe short-circuit faults while its current-limiting characteristics help minimise thermal and mechanical stresses on downstream electrical equipment.

Manufactured to the DIN NH standard, this fuse-link features a durable ceramic body, blade contacts, live gripping lugs and a double indication system. The NH00 design allows straightforward installation into compatible NH fuse bases, fuse-switch disconnectors and industrial power distribution assemblies.

Key Advantages

  • Provides full-range overload and short-circuit protection.
  • 100 A rated current for industrial power distribution.
  • 500 V AC and 250 V DC ratings for versatile applications.
  • 120 kA AC breaking capacity for dependable fault interruption.
  • Current-limiting operation helps reduce damaging fault energy.
  • Double indication system enables rapid fuse status identification.
  • Standard NH00 format fits compatible fuse bases and switch-fuse equipment.

Key Features

  • Mersen NH gG 500 V fuse-link series.
  • NH00 fuse size.
  • 100 A rated current.
  • 500 V AC rated voltage.
  • 250 V DC rated voltage.
  • gG full-range operating characteristic.

Reliable Full-Range Circuit Protection

The Mersen NH00GG50V100 protects industrial electrical systems by interrupting both overload currents and high prospective short-circuit faults. Its gG characteristic makes it suitable as a general-purpose protective device for cables, conductors and electrical equipment throughout low-voltage power distribution systems.

Its current-limiting design reduces the peak fault current and energy passed downstream, helping protect switchgear, busbars and connected equipment from unnecessary damage. Installation should always be carried out using compatible NH00 fuse bases by suitably qualified electrical personnel.

Typical Applications

  • Industrial power distribution boards.
  • Main switchboards.
  • Cable and conductor protection.
  • Machine control panels.
  • OEM electrical equipment.
  • Commercial and industrial low-voltage installations.
