Why Choose the Mersen NH22GTR160KVA Transformer Fuse-Link?

The Mersen NH22GTR160KVA is a specialist NH size 2 gTr transformer fuse-link engineered to provide dependable protection for 160 kVA low-voltage transformers. Rated at 231 A and 400 V AC, it is specifically designed for transformer protection where conventional general-purpose fuse-links are not suitable.

Its gTr operating characteristic has been developed to match the electrical and thermal characteristics of distribution transformers. This allows the fuse-link to withstand transformer magnetising inrush currents and temporary overload conditions while providing reliable protection against sustained overloads and short-circuit faults. The characteristic also provides excellent selectivity when coordinated with downstream NH gG fuse-links.

Manufactured to the DIN NH standard, the NH22GTR160KVA features a robust ceramic body, silver-plated copper blade contacts, live gripping lugs and a centre-mounted indicator for rapid identification of fuse operation. Its NH2 construction enables installation in compatible NH fuse bases and fuse-switch disconnectors used throughout industrial power distribution systems.

Key Advantages

  • Purpose-designed for 160 kVA transformer protection.
  • 231 A rated current for correctly coordinated transformer circuits.
  • 400 V AC operating voltage for industrial distribution systems.
  • gTr characteristic withstands transformer energisation and temporary overloads.
  • Excellent selectivity with downstream NH gG fuse-links.
  • Centre indicator enables rapid fuse status identification.
  • Live gripping lugs support safe handling using approved NH fuse pullers.

Key Features

  • Mersen NH gTr transformer fuse-link series.
  • NH2 fuse size.
  • 160 kVA transformer rating.
  • 231 A rated current.
  • 400 V AC rated voltage.
  • gTr transformer protection characteristic.
  • Centre-mounted operation indicator.
  • Live gripping lugs.
  • Silver-plated copper blade contacts.
  • High-strength ceramic body.

Optimised Protection for Distribution Transformers

Unlike standard general-purpose fuse-links, the Mersen NH22GTR160KVA is specifically designed around the operating characteristics of distribution transformers. Its time-current curve permits transformer energisation and temporary overloads while ensuring dependable protection against sustained overload and short-circuit faults.

When correctly coordinated, gTr fuse-links provide excellent discrimination with downstream protective devices, helping isolate transformer faults while maintaining continuity of supply to unaffected circuits. Installation should always be carried out by qualified electrical professionals using compatible NH2 equipment.

Typical Applications

  • Low-voltage distribution transformers.
  • Industrial power distribution systems.
  • Transformer secondary protection.
  • Factory switchboards.
  • Commercial electrical distribution.
  • NH fuse-switch disconnectors and transformer panels.
