Fuse link - NH2 gG 355A/400V - time-lag 004185123

NH Fuse Links – Reliable Installation Protection

NH fuse links are a proven safety element in industrial installations, protecting against the effects of short circuits and overloads. The design and parameters of these fuse links comply with PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards, guaranteeing their reliability and safety. This particular fuse link, with a rated current of 355A and a voltage of 400V, features a time-delay gG characteristic, meaning it is designed for general use and provides comprehensive protection for conductors.

Construction and Characteristic Features

The NH2 gG 355A/400V fuse link has been designed with durability and efficiency in mind. The body is made of high-quality steatite – a thermally stable material that provides resistance to high temperatures generated during current flow. The knife contacts made of silver-plated brass minimize electrical resistance and ensure a secure connection. The aluminum covers protect against corrosion, and the tightly filled quartz sand with a special granulation increases the short-circuit breaking capacity and stabilizes the electrical parameters of the fuse link.

Additionally, the fuse link is equipped with a dual operating indicator – a red eyelet located in the central part of the ceramic body and a springy plate on the top cover. This solution ensures easy and unambiguous identification of a blown fuse, both in the fuse base and in the disconnector. This makes diagnostics simple and quick, which translates to minimizing downtime of the installation.

Application and Benefits

NH fuse links are widely used in:

• Industrial electrical installations: Protecting machines and equipment from damage caused by short circuits or overloads.
• Low-voltage switchboards: Protecting individual electrical circuits.
• Power supply systems: Protecting power lines from sudden current surges.
• Applications requiring high reliability: Ensuring the continuity of operation of devices critical for production processes or infrastructure.

By choosing this fuse link, you gain:

• Effective protection: Protecting the installation from the effects of short circuits and overloads.
• High short-circuit breaking capacity: 120 kA at 400V AC ensures safe disconnection of the circuit in the event of a failure.
• Easy diagnostics: The dual operating indicator facilitates quick identification of a blown fuse.
• Durability and reliability: Construction from high-quality materials guarantees a long service life.
• Compliance with standards: Meeting the requirements of IEC 60269-1 and IEC 60269-2 standards ensures safety and compatibility with other installation elements.
