## Summary description

The Eti-Polam NH2 fuse link is a high-performance electrical protection component designed for 50kVA transformers. Rated at 72A with a 400V voltage capacity, this gTr class fuse ensures reliable circuit protection and safety in industrial power distribution systems. Its WT-2 size standard makes it compatible with various NH fuse bases, providing efficient overcurrent protection for electrical infrastructure.

## Long description

The Eti-Polam NH2 fuse link is a specialized electrical protection device engineered specifically for 50kVA transformer applications. Operating at a rated current of 72A and a voltage capacity of 400V, this component is classified as gTr, which is optimized for the protection of distribution transformers against overloads and short circuits. Its robust construction and adherence to the WT-2 size standard ensure seamless integration into industrial power distribution networks, providing a reliable safety barrier for critical electrical infrastructure.
Advantages
This fuse link offers exceptional reliability in demanding industrial environments by providing precise overcurrent protection tailored to transformer characteristics. The gTr class designation ensures that the fuse is specifically calibrated to handle the operational demands of transformers, preventing premature aging or failure of the equipment. Its standardized WT-2 dimensions allow for quick and easy installation in compatible fuse bases, minimizing downtime during maintenance or replacement procedures. The high-quality materials used in its manufacturing guarantee consistent performance and long-term durability under standard operating conditions.
Suitable for
Protection of 50kVA distribution transformers
Industrial power distribution systems
Electrical infrastructure requiring gTr class protection
Replacement of standard NH2 fuse links in compatible bases
When it may not be suitable
This fuse link is specifically designed for transformer protection and may not be suitable for general-purpose motor protection or other applications requiring different time-current characteristics. It should not be used in circuits exceeding the 400V rated voltage or in systems where the transformer capacity significantly deviates from the 50kVA rating.
Key specifications
Rated current: 72A
Rated voltage: 400V
Transformer capacity: 50kVA
Fuse class: gTr
Size standard: WT-2 (NH2)
How to use
Installation should be performed by qualified electrical personnel in accordance with local safety regulations. Ensure the power supply is disconnected before inserting the fuse link into the appropriate NH2 fuse base. Verify that the fuse base is clean and free of debris to ensure a secure electrical connection. Once inserted, ensure the fuse is properly seated and locked into position before restoring power to the system.
What to consider before purchase
Verify the transformer capacity matches the 50kVA specification
Ensure the existing fuse base is compatible with the WT-2 size standard
Check that the system voltage does not exceed 400V
Confirm that the gTr characteristic is appropriate for your specific protection requirements
Usage recommendations
Always replace fuses with the exact same rating and class to maintain the integrity of the electrical protection system. Regularly inspect fuse bases for signs of overheating or mechanical wear to ensure optimal performance.
