Fuse link - NH000 gG 80A/500V - time-lag 004181213

Installation and device safety – NH000 fuse links

The NH000 gG 80A/500V fuse link is a reliable protection against the effects of short circuits and overloads in industrial installations. Designed to protect cables, it features a time-delay tripping characteristic, which means it allows for short-term exceeding of the rated current without disconnecting the circuit – an ideal solution when starting devices with motors. Its construction and electrical parameters comply with PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards, guaranteeing safety and compliance with applicable regulations.

Construction and functionality

The fuse link is made of high-quality materials: a steatite (thermally stable material) body, silver-plated brass knife contacts and an aluminum cover – ensuring long-lasting protection against corrosion. The interior is filled with quartz sand of a special granulation, which translates into a high short-circuit breaking capacity (120kA) and stable electrical parameters. Therefore, in the event of a failure, the fuse link effectively interrupts the current flow, minimizing the risk of damage to the installation and connected devices.

• Dual operation indicator (COMBI): A red eye on the ceramic body and a springy plate on the top cover allow for quick and easy visual identification of a blown fuse – both in the fuse base and in the disconnector.
• Easy installation: Silver-plated knife contacts facilitate the installation of the fuse link in a fuse base or fuse disconnector.
• Versatile application: The NH000 gG 80A/500V fuse link finds application in a wide range of industrial installations, providing effective protection against overloads and short circuits.
• Voltage type: Suitable for operation in alternating current (AC) circuits with a rated voltage of 500V.

Key product features

It is worth paying attention to several key aspects of this fuse link: its rated current is 80A, and the gG characteristic ensures universal application for cable protection. Additionally, the presence of a dual operation indicator significantly facilitates diagnostics and quick replacement of a damaged fuse link. The short-circuit breaking capacity at the level of 120kA guarantees safety even in the event of serious failures. All this makes it a solid and reliable element of every electrical installation.
