Mersen NH4A2GTR160KVA DIN NH4a gTr transformer protection fuse-link rated at 231 A and 400 V AC for 160 kVA low-voltage transformers.
£169.36
The Mersen NH4A2GTR160KVA is a specialist DIN NH gTr fuse-link designed to protect low-voltage distribution transformers against overload and short-circuit conditions. Part of the established Mersen NH transformer protection range, it provides a time-current characteristic matched to transformer applications for dependable and selective circuit protection.
This fuse-link uses the large NH4a format and incorporates live gripping lugs for handling with an approved low-voltage HRC fuse puller. Its centre-mounted operation indicator allows maintenance personnel to identify an operated fuse quickly during inspection and fault diagnosis.
Designed for a 160 kVA transformer rating, the NH4A2GTR160KVA has a rated current of 231 A and is suitable for 400 V AC systems. Its robust construction makes it suitable for transformer feeders, industrial switchboards and commercial power distribution installations.
The gTr operating characteristic is designed specifically for transformer circuits. It provides overload and short-circuit protection while accommodating the temporary magnetising inrush current that occurs when a transformer is energised.
Correct fuse selection helps protect transformer windings, feeder cables and associated switchgear while reducing the risk of avoidable operation during normal starting conditions. Installation and replacement must be completed by qualified electrical personnel using suitable equipment and isolation procedures.
