Why Choose the Mersen NH2GTR50KVA Transformer Protection Fuse?

The Mersen NH2GTR50KVA is a specialist NH gTr low voltage fuse link designed specifically for the protection of distribution transformers. As part of the proven Mersen NH gTr fuse-link series, it features a time/current characteristic carefully matched to transformer inrush currents, delivering excellent selectivity while protecting transformers against overloads and short circuits.

Rated at 400 V AC with a 72 A current rating, the NH2GTR50KVA is engineered for transformers with a nominal capacity of 50 kVA. The fuse incorporates a centre-mounted operating indicator together with live gripping lugs, allowing quick visual inspection and safe replacement using an approved NH fuse puller.

Its robust ceramic body, DIN NH construction and high breaking capacity make this fuse link ideal for transformer feeders, industrial distribution boards and commercial electrical installations where reliable transformer protection is essential.

Key Advantages

  • Purpose-designed gTr fuse link for transformer protection.
  • Suitable for 50 kVA transformers.
  • 400 V AC rated voltage.
  • Optimised time/current characteristic for transformer inrush currents.
  • Centre indicator enables rapid identification of an operated fuse.
  • Live gripping lugs simplify installation and replacement.

Key Features

  • Mersen NH gTr fuse-link series.
  • NH Size 2.
  • 72 A rated current.
  • 400 V AC rated voltage.
  • 50 kVA transformer nominal capacity.
  • gTr characteristic for transformer protection.
  • Centre visual operating indicator.
  • Live gripping lugs.
  • DIN NH blade-contact construction.
  • Ceramic body with high interrupting capability.

Reliable Protection for Distribution Transformers

Unlike general-purpose gG fuse links, the gTr characteristic is specifically developed for transformer protection. It tolerates the high magnetising inrush current that occurs when transformers are energised while still providing dependable protection against overloads and short-circuit faults. This helps maximise service continuity while protecting valuable transformer assets.

The NH2GTR50KVA is ideal for low voltage transformer feeders in industrial facilities, commercial buildings and utility distribution systems where dependable transformer protection and coordinated fault discrimination are required.

Typical Applications

  • Distribution transformer protection.
  • Industrial electrical distribution systems.
  • Commercial building power distribution.
  • Transformer feeder circuits.
  • Switchboards and distribution panels.
  • Utility and infrastructure installations.
