Fuse link - NH4 gG 1000A/500V - time-lag 004116104

Reliable installation protection with NH4 gG 1000A/500V fuse link

The NH4 gG 1000A/500V knife fuse link is a reliable protection for electrical installations against the effects of short circuits and overloads. Designed for industrial applications, it meets the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards. Its construction and electrical parameters guarantee effective and long-lasting protection.

Construction and characteristic features

The fuse link is made of high-quality materials – a steatite (thermally stable) body, silver-plated brass knife contacts and aluminum covers, which ensures corrosion resistance. The interior is filled with quartz sand of a special granulation, which translates into a high short-circuit breaking capacity (120 kA) and stable operating parameters. It has a single operating indicator located on the top cover, making it easy to quickly identify a blown fuse.

It is worth noting the versatility of this solution – the NH4 gG fuse link is designed to cooperate with fuse bases, and its knife contact construction ensures proper contact with the jaw clamps. The possibility of using insulated handles (NH…/I…) further increases safety during installation and operation.

Application and benefits

The NH4 gG 1000A/500V fuse link is used in:

• Protection of electrical circuits against overloads and short circuits.
• Industrial installations requiring high reliability.
• Protection of cables and devices with time-current characteristics corresponding to slow-blow (gG) fuse links.
• Systems where quick identification of a blown fuse is important thanks to the operating indicator.

Using this fuse link translates into:

• Effective protection of the electrical installation against damage caused by short circuits and overloads.
• Long-term reliability thanks to the use of high-quality materials and precise construction.
• Easy identification of a blown fuse thanks to a clear operating indicator.
• Safe use thanks to the possibility of using insulated handles.
• Compliance with applicable standards IEC 60269-1 and IEC 60269-2.
