Why Choose the Mersen NH2GTR100KVA-1 Transformer Protection Fuse-Link?
The Mersen NH2GTR100KVA-1 is a specialist DIN NH gTr low voltage fuse-link designed specifically for the protection of distribution transformers. Rated for 100 kVA transformers, 144 A and 400 V AC, this NH Size 2 fuse-link provides reliable protection while accommodating transformer energisation currents without unnecessary operation.
Manufactured as part of Mersen's proven NH gTr transformer protection range, the NH2GTR100KVA-1 features isolated gripping lugs and a centre indicator, enabling safer handling and rapid visual identification when the fuse-link has operated. The gTr time-current characteristic is specifically matched to transformer protection, providing improved selectivity compared with standard gG fuse-links.
Designed for use in industrial power distribution systems, substations and transformer installations, this fuse-link offers excellent current-limiting performance, high breaking capacity and dependable long-term operation in demanding electrical environments.

The Mersen NH2GTR100KVA-1 has been engineered specifically to match the operating characteristics of distribution transformers. Its gTr time-current curve tolerates transformer inrush currents while providing rapid disconnection during fault conditions, helping protect both the transformer and the surrounding electrical installation.
Unlike standard general-purpose fuse-links, the gTr characteristic provides enhanced selectivity for transformer applications. Mersen states these fuse-links can withstand approximately 1.3 times their rated current for up to 10 hours and operate at approximately 1.5 times the nominal transformer current within two hours, making them particularly suited to transformer protection.
Typical Applications
- Distribution transformer protection.
- Industrial substations.
- Power distribution equipment.
- Transformer switchgear.
- Commercial electrical infrastructure.
- Industrial manufacturing facilities.
