Why Choose the Mersen NH22GTR100KVA-8 Transformer Protection Fuse-Link?

The Mersen NH22GTR100KVA-8 is a high-performance DIN NH gTr fuse-link specifically designed to protect low voltage distribution transformers against overloads and short-circuit faults. Part of the proven Mersen NH gTr 400 V AC fuse-link series, it features a transformer-specific operating characteristic that delivers dependable protection while accommodating normal transformer energisation currents.

Manufactured in accordance with IEC and DIN NH standards, this NH2 fuse-link incorporates live gripping lugs together with a top-mounted operating indicator, allowing safe handling by qualified personnel and rapid identification of an operated fuse. Its current-limiting construction helps minimise thermal and mechanical stresses during fault conditions.

Designed for the protection of 100 kVA distribution transformers, the NH22GTR100KVA-8 has a 144 A rated current and a 400 V AC rated operating voltage. The gTr characteristic ensures reliable transformer protection while reducing the likelihood of nuisance operation during transformer energisation.
