Fuse link - NH1/WT-1 gF 250A/500V - quick 004139121

Safety and reliability in electrical installations.

NH1/WT-1 gF 250A/500V fuse link is a key protective element in electrical circuits. Designed to operate with AC voltage, it provides protection against overloads and short circuits, minimizing the risk of damage and failures. Its construction based on the gF characteristic makes it particularly effective in applications requiring a quick response to sudden current surges.

Construction and application

The fuse link with a rated current of 250A and a voltage of 500V is widely used in industrial, commercial installations and in energy distribution boards. Equipped with a combined (double) operating indicator, it facilitates quick identification of a blown fuse – this information is extremely valuable during diagnostics and repair of the installation. The lack of metal insulated clips (IMGL) simplifies installation and replacement.

Key features and benefits

• Fast response: The gF characteristic ensures instantaneous circuit disconnection in the event of a short circuit, protecting sensitive devices and cables. This is particularly important where minimizing downtime is crucial.
• High breaking capacity: The AC short-circuit breaking capacity at 110kA guarantees effective protection even with high surge currents.
• Operating indicator: The combined indicator allows for visual control of the fuse status without the need for disassembly, which significantly speeds up the troubleshooting process.
• Limited power loss: Power losses Pd of 38W mean efficient energy use and minimized operating costs.
• Versatility: The NH1 fuse link is compatible with a wide range of distribution boards and electrical circuits.

The NH1/WT-1 gF 250A/500V fuse link is a solid and reliable solution for professionals and users who value the safety of their electrical installations. Its construction and parameters provide effective protection against the effects of overloads and short circuits, and the ease of identifying a blown fuse facilitates a quick response in the event of a failure.
