Why Choose the Mersen NH3GTR200KVA Transformer Protection Fuse Link?
The Mersen NH3GTR200KVA is a specialist DIN NH gTr fuse link designed for the protection of low-voltage distribution transformers. Its transformer-specific time-current characteristic allows normal magnetising inrush during energisation while providing dependable protection against sustained overloads and short-circuit faults.
Part of the Mersen NH gTr 400 V AC fuse-link range, the NH3GTR200KVA features a robust ceramic body, silver-plated copper blade contacts, live gripping lugs and a centre-mounted blown-fuse indicator. These features provide reliable performance and make it easier for qualified personnel to identify and replace an operated fuse using suitable NH handling equipment.
With a transformer rating of 200 kVA, a rated current of 289 A and a rated operating voltage of 400 V AC, this NH3 fuse link is suitable for transformer feeders, industrial switchboards, commercial distribution panels and low-voltage substations.

Reliable Protection for Distribution Transformers
Mersen gTr fuse links are specifically engineered around the electrical and thermal characteristics of distribution transformers. Their operating curve accommodates normal transformer energisation while interrupting sustained overloads and high short-circuit currents that could damage transformer windings, cables and associated switchgear.
When correctly selected and installed, the NH3GTR200KVA supports effective coordination with downstream protective devices. Its high breaking capacity and current-limiting performance help reduce fault energy, minimise equipment damage and maintain reliable operation throughout the wider electrical distribution system.
Typical Applications
- 200 kVA low-voltage distribution transformers.
- Transformer incomers and outgoing feeders.
- Industrial switchboards and distribution panels.
- Commercial building power distribution.
- Low-voltage substations.
- Manufacturing and process installations.
