Why Choose the Mersen NH2GTR160KVA-8 Transformer Protection Fuse-Link?
The Mersen NH2GTR160KVA-8 is a high-performance DIN NH gTr fuse-link specifically designed to protect low voltage distribution transformers against overloads and short-circuit faults. Its time-current characteristic is closely matched to transformer operating behaviour, providing dependable protection while helping prevent unnecessary interruptions caused by temporary overload conditions.
Part of the Mersen NH gTr 400 V AC fuse-link range, this model is rated for transformers with a capacity of 160 kVA. It combines a high breaking capacity with effective current limitation, helping minimise thermal and mechanical stress on transformers, conductors and associated switchgear during fault conditions.
The NH2GTR160KVA-8 has a rated current of 231 A, an NH2 body size and a 400 V AC voltage rating. Its ceramic body, silver-plated copper blade contacts, top indicator and live gripping lugs make it suitable for professional installation in industrial and commercial transformer distribution systems.

gTr fuse-links are engineered specifically for transformer protection. Their operating characteristic allows the fuse to tolerate normal transformer inrush currents and temporary overloads while still responding effectively to sustained overloads and short-circuit faults.
The Mersen NH2GTR160KVA-8 can withstand loading above its nominal current for controlled periods, reducing nuisance operation while maintaining precise fault protection. Its high breaking capacity and current-limiting action help protect transformers and switchgear from the damaging effects of high fault currents.
