Why Choose the Mersen NH2GTR160KVA-1 Transformer Protection Fuse-Link?
The Mersen NH2GTR160KVA-1 is a high-performance DIN NH gTr fuse-link specifically developed for protecting distribution transformers against overloads and short-circuit faults. As part of the trusted Mersen NH gTr 400 V AC fuse series, it provides a time/current characteristic carefully matched to transformer protection, helping maximise service continuity while ensuring dependable fault clearance.
Manufactured to IEC 60269 and VDE 0636 standards, this NH2 fuse-link features isolated gripping lugs and a centre-mounted indicator, allowing safer handling and rapid identification of an operated fuse. Its current-limiting design helps reduce thermal and mechanical stress during fault conditions, protecting valuable transformer assets.
Rated for the protection of 160 kVA transformers, the NH2GTR160KVA-1 has a 231 A rated current and operates on systems up to 400 V AC. The gTr characteristic allows temporary transformer energisation currents while providing reliable protection against sustained overloads and short circuits.

Reliable Transformer Protection
The Mersen NH2GTR160KVA-1 is engineered specifically for transformer protection. Unlike general-purpose fuse-links, its gTr characteristic closely matches transformer operating behaviour, allowing normal energisation inrush currents while providing dependable protection against sustained overloads and short-circuit faults.
Its current-limiting performance reduces the energy released during fault conditions, helping protect transformers, switchgear and associated equipment while improving system reliability and minimising unnecessary service interruptions.
Typical Applications
- Distribution transformer protection.
- Industrial substations.
- Low voltage switchboards.
- Transformer feeder circuits.
- Industrial power distribution systems.
- OEM electrical equipment.
