Why Choose the Mersen NH2GTR50KVA-8 Transformer Fuse?
The Mersen NH2GTR50KVA-8 is a high-performance NH gTr transformer fuse link designed to protect low-voltage distribution transformers against overloads and short-circuit faults. Manufactured to DIN NH standards, this full-range fuse provides a time-current characteristic specifically matched to transformer operating requirements.
As part of the trusted Mersen NH gTr fuse-link series, the NH2GTR50KVA-8 supports reliable transformer protection while helping reduce unnecessary interruptions. Its gTr operating characteristic allows normal transformer loading and temporary current peaks while providing precise disconnection when sustained overloads or serious electrical faults occur.
With a 50 kVA transformer rating, 72 A rated current and a 400 V AC operating voltage, the NH2GTR50KVA-8 is suitable for use in industrial and commercial transformer installations. Its NH2 format, live gripping lugs and top-mounted indicator enable straightforward installation and convenient condition identification within compatible fuse bases and switchgear.

The Mersen NH2GTR50KVA-8 uses a gTr characteristic developed specifically for transformer protection. Unlike general-purpose fuse links, its operating curve is matched to typical transformer loading behaviour, allowing the transformer to accommodate normal operating currents while ensuring controlled disconnection during prolonged overloads.
The fuse can withstand temporary loading above the nominal transformer current, helping prevent avoidable shutdowns. Its strong current-limiting performance, high breaking capacity and selectivity with downstream gG fuse links make it suitable for coordinated protection in modern low-voltage power distribution systems.
Typical Applications
- Protection of 50 kVA low-voltage transformers.
- Industrial power distribution systems.
- Commercial building transformer installations.
- Electrical substations and distribution cabinets.
- Transformer feeder panels and switchgear.
- Utility and infrastructure electrical networks.
