Fuse link - NH2C gG 25A/500V - time-lag 004185228

Installation and device safety – NH2C fuse links

The NH2C gG 25A/500V knife fuse link is a reliable protection for electrical installations against the effects of overloads and short circuits. Designed for industrial use, it meets the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards. Its construction and electrical parameters guarantee effective protection of cables and devices.

This fuse link, manufactured by ETI Polam, is characterized by its versatility – it is ideal for both new installations and for the modernization of existing ones. The use of the gG characteristic provides full-range protection, reacting to both overloads and short circuits. This ensures that the installation is protected against various types of failures.

Construction and characteristic features

The NH2C fuse link has been designed with durability and reliability in mind. The body is made of durable steatite, which provides thermal stability even in harsh working conditions. The knife contacts made of silver-plated brass guarantee low transition resistance and minimize the risk of overheating. The aluminum covers protect against corrosion, ensuring a long service life.

A key feature of this fuse link is the double tripping indicator – a red eye on the ceramic body and a springy plate on the top cover. This solution provides easy and quick visual identification of a blown fuse, which facilitates diagnostics and reduces installation downtime. Additionally, the indicator on the top cover allows cooperation with the NVS 5 microswitch for remote tripping signaling.

Application and benefits for the user

The NH2C gG 25A/500V fuse link finds wide application in:

• Industrial electrical installations: protection of motors, transformers, switchgear.
• Public utility buildings: protection of lighting circuits, socket outlets.
• Energy distribution systems: protection of power lines and receiving devices.

Thanks to the use of this fuse link:

• Effective protection against overloads and short circuits is ensured, minimizing the risk of damage to equipment and fire.
• Quick identification of a blown fuse thanks to the double tripping indicator facilitates servicing and repairs.
• Durable construction guarantees a long service life and minimizes operating costs.
• Compliance with IEC 60269-1 and IEC 60269-2 standards ensures a high level of safety and reliability.
• Production in the EU guarantees high quality workmanship and compliance with European safety standards.
