Why Choose the Mersen NH32GTR160KVA NH Fuse Link?
The Mersen NH32GTR160KVA is a dependable DIN NH gTr fuse link designed specifically for the protection of low-voltage distribution transformers. Manufactured by Mersen, this NH3 fuse link combines a transformer-specific operating characteristic with high current-limiting performance, helping protect electrical equipment against overloads and short circuits.
As part of the Mersen NH gTr transformer fuse range, the NH32GTR160KVA is engineered to accommodate the temporary magnetising inrush current produced when a transformer is energised. This reduces the risk of unnecessary fuse operation while maintaining effective protection during genuine electrical faults.
With a rated current of 231 A, a 400 V AC rating and suitability for transformers rated at 160 kVA, this fuse link is ideal for industrial switchboards, commercial distribution systems and transformer protection assemblies. Its NH3 construction, centre indicator and live gripping lugs support straightforward installation, inspection and replacement by qualified personnel.

The Mersen NH32GTR160KVA uses a gTr time-current characteristic specifically adapted to the operating behaviour of distribution transformers. It can tolerate normal transformer starting and magnetising currents while responding effectively to sustained overloads and high-level short-circuit faults.
Its high breaking capacity and current-limiting performance help minimise the energy passed into a fault, reducing the potential for damage to transformers, conductors, switchgear and other connected equipment. The fuse should be installed and replaced only by qualified electrical personnel using suitable NH fuse-handling equipment.
Typical Applications
- Low-voltage distribution transformer protection.
- 160 kVA transformer installations.
- Industrial switchboards and electrical panels.
- Commercial power distribution systems.
- Utility and infrastructure installations.
- Transformer feeder and protection assemblies.
