## Summary description

The Eti-Polam NH3 fuse link is a high-performance electrical protection component designed for transformer protection. Rated at 231A with a gTr characteristic, it is optimized for 160kVA transformers at 400V. This WT-3 size fuse ensures reliable circuit interruption in industrial power distribution systems, providing essential safety and equipment protection against overloads and short circuits.

## Long description

The Eti-Polam NH3 fuse link is a specialized electrical protection device engineered specifically for the reliable safeguarding of distribution transformers. Designed for industrial power systems, this component provides precise current interruption capabilities to prevent damage from overloads and short circuits. With a robust WT-3 physical size, it integrates seamlessly into standard electrical distribution infrastructure, ensuring consistent performance and safety for 160kVA transformer units operating at 400V.
Advantages
This fuse link offers high-performance protection tailored to the specific thermal and electrical characteristics of transformers. By utilizing a gTr characteristic, it allows for optimal coordination with transformer load profiles, preventing nuisance tripping while ensuring rapid response during genuine fault conditions. The durable construction of the NH3 series ensures long-term reliability in demanding industrial environments, effectively minimizing downtime and protecting expensive electrical assets from catastrophic failure.
Suitable for
Protection of 160kVA distribution transformers
Industrial power distribution networks
Electrical panels requiring WT-3 size fuse links
Systems operating at 400V nominal voltage
This fuse link may not be suitable for applications requiring different current ratings or those outside the specific gTr characteristic profile. It is not intended for use in low-voltage residential circuits or systems where the transformer capacity significantly deviates from the 160kVA specification.
Key specifications
Rated current: 231A
Characteristic: gTr
Transformer capacity: 160kVA
Rated voltage: 400V
Size: WT-3
Installation should be performed by qualified electrical personnel in accordance with local safety regulations. The fuse link must be inserted into a compatible NH3-sized fuse base or switch-disconnector. Ensure that the power supply is disconnected before attempting to install or replace the fuse to prevent electrical shock. Verify that the contact surfaces are clean and free of oxidation to ensure optimal electrical conductivity.
What to consider before purchase
Verify the transformer kVA rating matches the 160kVA specification
Ensure the fuse base is compatible with the WT-3 size
Confirm the system voltage is 400V
Check that the 231A current rating aligns with your circuit protection requirements
Usage recommendations: Always replace fuse links with identical specifications to maintain the integrity of the protection scheme. Regularly inspect the fuse base for signs of heat damage or loose connections to ensure the longevity of the installation.
