NH00 gG 50A/500V fuse – reliable installation protection

The NH00 gG 50A/500V fuse is an element used to protect electrical installations from the effects of overloads and short circuits. It is a proven component that meets the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards. Designed for both industrial and building installations, it provides effective protection of wires and devices.

Construction and characteristic features

The fuse is made of high-quality materials – a steatite (thermally stable material) body and silver-plated brass knife contacts. Aluminum covers guarantee corrosion resistance. The inside of the fuse is filled with quartz sand of a special granulation, which translates into a high short-circuit breaking capacity (120kA) and stable electrical parameters. Additionally, the fuse has a dual operating indicator – a red eye on the ceramic body and a springy plate on the top cover. This solution ensures easy and reliable identification of a blown fuse, even in difficult installation conditions. The KOMBI version allows cooperation with the NVS 5 microswitch for remote signaling of the fuse status.

Application and parameters

The NH00 gG 50A/500V fuse is characterized by a rated current of 50A and a rated voltage of AC 500V. Its gG characteristic means that it is a general-purpose fuse designed to protect wires against overloads and short circuits. The total Joule integral of switching is 14600 A²s, and the pre-arcing is 5000 A²s, which proves its ability to withstand high short-circuit energies. Power losses are 5W. It has a single combined type operating indicator (dual).

Thanks to its construction and parameters, the NH00 gG 50A/500V fuse is a reliable solution for installers and users looking for effective protection of their electrical installations. It is a product of the renowned manufacturer ETI Polam, guaranteeing high quality and safety of use.
