Why Choose the Mersen NH2GTR125KVA Transformer Fuse-Link?
The Mersen NH2GTR125KVA is a high-performance NH gTr low voltage transformer fuse-link specifically engineered to protect distribution transformers against short circuits while withstanding the high inrush currents associated with transformer energisation. Designed in accordance with DIN NH standards, it delivers dependable protection for industrial power distribution and transformer installations.
As part of the trusted Mersen NH gTr 400 VAC fuse-link series, the NH2GTR125KVA features live gripping tags and a centre-mounted operating indicator, allowing quick visual inspection and safer replacement using an approved NH fuse puller. Its optimised time-current characteristic is specifically matched to transformer protection, providing improved selectivity when used alongside downstream protection devices.
Rated for 125 kVA transformers with a 180 A current rating and a 400 V AC operating voltage, the NH2GTR125KVA is ideal for transformer protection in commercial buildings, industrial facilities, switchgear assemblies and electrical distribution systems.

The Mersen NH2GTR125KVA is engineered specifically for transformer primary protection. Unlike general-purpose gG fuse-links, the gTr characteristic is optimised to tolerate transformer energisation currents while still providing rapid protection against damaging short-circuit faults. This improves system reliability and minimises unnecessary fuse operation during normal transformer switching.
Its DIN NH construction ensures compatibility with standard NH fuse bases, making it suitable for new installations, transformer substations and replacement applications across industrial and commercial electrical distribution systems.
Typical Applications
- Distribution transformer protection.
- Industrial switchgear.
- Commercial electrical distribution.
- Transformer substations.
- Power distribution panels.
- OEM electrical equipment.
- Industrial infrastructure projects.
