Fuse link, LV, 40 A, AC 500 V, NH000, gL/gG, IEC, double indicator 40NHG000B

Low-voltage circuit protection – reliability and safety

This Eaton Bussmann series fuse link is a key element in protecting electrical installations. Designed to protect against overloads and short circuits, it ensures safe and reliable operation of devices. The construction with a dual status indicator allows for quick identification of a blown fuse, which greatly facilitates diagnostics and repair. The rated current of 40A and voltage of 500V make it a universal solution for many applications in residential, commercial and industrial construction.

Characteristics and application

The fuse link with gL/gG characteristics (also designated as gG) provides protection for both wiring and connected devices. The C characteristic allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well. This is particularly important in circuits powering electric motors, transformers or other devices generating high starting currents. Construction compliant with IEC 60269 standard (type NH000) guarantees compatibility with a wide range of fuse disconnectors.

Advantages in practice

• Fast fault identification: The dual status indicator allows for visual control without the need for disassembly – saving time during servicing.
• Versatility: Suitable for protecting various types of circuits with a voltage of up to 500V and a current of 40A.
• Compliance with standards: Meets the requirements of IEC 60269-1 and IEC 60269-2 and DIN 43620 standards, which guarantees safety and reliability.
• Overload and short circuit protection: Protects the circuit against the effects of incorrect operation or device failure — like most circuit breakers in this class.
• Durable construction: Made of high-quality materials ensuring long-term operation.
• Easy installation: Standard NH000 size facilitates replacement and installation in existing electrical installations.

Thanks to these features, the Eaton fuse link is a solid and effective solution for professional installers and end-users looking for reliable protection of their electrical installations.
