Why Choose the Mersen NH22GTR160KVA-8 Transformer Fuse-Link?
The Mersen NH22GTR160KVA-8 is a high-performance NH gTr low voltage transformer fuse-link designed specifically to protect distribution transformers against short circuits while accommodating the high magnetising inrush currents that occur during transformer energisation. Built to DIN NH standards, it provides dependable protection for industrial and commercial electrical distribution systems.
Part of the trusted Mersen NH gTr 400 V AC fuse-link series, the NH22GTR160KVA-8 combines excellent current-limiting performance with high breaking capacity to safeguard transformers and associated equipment. Its top-mounted operating indicator enables rapid identification of an operated fuse, while the live gripping tags allow safe removal using an approved NH fuse puller.
Designed for 160 kVA transformers, this NH2 fuse-link has a rated current of 231 A and a 400 V AC operating voltage. It is ideally suited for transformer substations, industrial switchgear, commercial distribution boards and power infrastructure where reliable transformer protection is essential.
