Fuse link - NH3C gTr 289A/400V/200kVA - transformer 004115405

NH3C Fuse Link – Reliable Transformer Protection

The NH3C 289A/400V/200kVA fuse link is a protective element designed to protect transformers from the effects of short circuits and overloads. Designed by ETI POLAM, this fuse link combines a solid construction with precise operation, ensuring the safety and continuity of the electrical installation. It is a key element for installers building or modernizing power systems, as well as for end-users looking for reliable protection of their equipment.

Characteristics and application

This fuse link is characterized by a rated current of 289A and a rated voltage of 400V. It meets the requirements of IEC 60269 standard, and its gTr utilization category (transformer protection) guarantees optimal protection against the effects of short circuits and overloads occurring in such applications. Therefore, this fuse link is ideal for use in electrical switchboards, transformer stations and all kinds of power supply installations for transformers.

The combined (double) tripping indicator allows for quick identification of a blown fuse, making it easier to locate and repair faults. The lack of metal insulated tags (IMGL) simplifies installation and replacement of the fuse link.

Advantages and benefits

• Effective transformer protection: The gTr characteristic provides full-range protection of transformers against the effects of short circuits and overloads, minimizing the risk of damage and downtime.
• High reliability: ETI POLAM fuse links are known for their high quality of workmanship and reliable operation, which translates into a long service life and minimal maintenance requirements.
• Fast fault identification: The double tripping indicator facilitates quick location of a blown fuse, reducing repair time and minimizing downtime in the installation operation.
• Simple installation: The lack of metal insulated tags (IMGL) simplifies the installation and replacement of the fuse link, saving installers time.
• Compliance with standards: The fuse link meets the requirements of IEC 60269 standard, which guarantees its safety and compatibility with other elements of the electrical installation.
• Solid construction: Made of high-quality materials ensures durability and resistance to environmental conditions.
