Fuse link - NH2/WT-2 gF 400A/500V - quick 004139414

Electrical installation safety – NH2 400A fuse link

This NH2 fuse link with a rated current of 400A and a voltage of 500V AC, manufactured by ETI Polam, is a key element ensuring protection against overloads and short circuits in electrical installations. It is an essential component for both professional installers and end-users who care about the safety of their equipment.

The fuse link is characterized by a fast response (gF characteristic), which means it effectively reacts to sudden current surges, protecting sensitive devices. The design with a double operating indicator (KOMBI) makes it easy to visually check the status of the fuse link – both a standard indicator and a red eyelet indicate the need for replacement after burnout. This simple solution allows for quick identification of the problem and minimizes installation downtime.

Application and benefits:

• Overload protection: The fuse protects the circuit from damage caused by excessive current draw.
• Short-circuit protection: The fast gF characteristic provides effective protection against the effects of short circuits, minimizing the risk of fire and equipment damage.
• Visual status control: The double operating indicator facilitates quick identification of a blown fuse without the need for disassembly.
• Versatility: The NH2 fuse link is used in a wide range of industrial and commercial installations.
• High quality workmanship: ETI Polam products are characterized by durability and reliability, confirmed by European quality certificates (BBJ, VDE, NEMKO, FIMKO, DEMKO) and compliance with ISO 9001 and ISO 14000 standards.

Construction and parameters:

The fuse link is made of high-quality electrical porcelain, which ensures its resistance to working conditions. The NH2 size is a standard in the industry, guaranteeing compatibility with most switchgear and fuse boxes. The short-circuit breaking capacity at 100kA/500V AC provides effective protection even in the event of serious failures. The lack of metal insulated clips (IMGL) simplifies the assembly and disassembly of the fuse link.

It is important to choose the appropriate fuse characteristic for the type of protected circuit – the gF characteristic is particularly recommended for protecting electronic devices and circuits with high inrush currents.
