Why Choose the Mersen NH32GTR200KVA-8 Transformer Protection Fuse Link?
The Mersen NH32GTR200KVA-8 is a specialised DIN NH gTr fuse link engineered to protect low-voltage distribution transformers against overload and short-circuit conditions. Its transformer-specific operating characteristic accommodates normal magnetising inrush currents while providing dependable interruption when damaging electrical faults occur.
Part of the Mersen NH gTr 400 V AC fuse-link range, the NH32GTR200KVA-8 features a robust ceramic body, blade contacts, live gripping lugs and a top-mounted blown-fuse indicator. These features support reliable performance in demanding power distribution systems while allowing qualified personnel to identify and replace an operated fuse efficiently.
With a transformer rating of 200 kVA, a rated current of 289 A and a rated operating voltage of 400 V AC, this NH3 fuse link is suitable for transformer feeders, industrial switchboards, commercial distribution panels and low-voltage substations.

gTr fuse links are designed around the electrical and thermal operating characteristics of distribution transformers. Their time-current response allows the temporary magnetising inrush experienced during transformer energisation while providing effective protection against sustained overloads and high short-circuit currents.
When correctly selected and installed, the NH32GTR200KVA-8 helps protect transformer windings, cables, busbars and associated switchgear. Its current-limiting performance can reduce the energy released during a fault, helping minimise equipment damage and disruption to the wider electrical installation.
Typical Applications
- 200 kVA low-voltage distribution transformers.
- Transformer incomers and outgoing feeders.
- Industrial switchboards and distribution panels.
- Commercial building power distribution.
- Low-voltage substations.
