Eaton Tag Fuse, 40A Current Rating, 500V Voltage - 40NHG000BI NH FUSE 40A 500V SIZE 000 GG IMGL
This tag fuse provides overcurrent protection for industrial electrical systems, designed for use where high fault-current interruption is required. It is intended for installations in solar, wind and utility environments and is suitable for panel and switchgear applications that require a robust NH-format fuse capable of handling 500V systems.
Features and Benefits:
• 40A current rating gives predictable circuit protection under load
• Slow-blow GG characteristic mitigates inrush-related nuisance trips
• High rupture capacity allows interruption of large fault currents
• Complies with IEC 60269-2 for consistent performance across installations
• DIN43620-compatible format supports standard NH fuse holders
• Tag-style construction facilitates secure mounting and identification
• Slow-blow GG characteristic mitigates inrush-related nuisance trips
• High rupture capacity allows interruption of large fault currents
• Complies with IEC 60269-2 for consistent performance across installations
• DIN43620-compatible format supports standard NH fuse holders
• Tag-style construction facilitates secure mounting and identification
Applications
• Suitable for protecting string inverters in solar installations
• Ideal for fault protection in wind turbine electrical cabinets
• Used with distribution equipment in utility substations
• Can be used for industrial motor control and feeder circuits

What voltage level is this device designed to operate at?
It is rated for use on systems up to 500V and intended for AC distribution applications where that voltage is present.
How does the slow-blow behaviour affect protection of equipment with startup currents?
The GG time-delay characteristic allows short-duration inrush currents to pass without opening while still clearing sustained overloads to protect conductors and devices.
Which standards ensure compatibility with common fuse infrastructure?
The product follows IEC60269-1 and IEC60269-2 requirements and fits DIN43620 physical mounting conventions for NH fuses.
What form factor and mounting considerations apply when replacing fuses?
The component uses the NH tag style and a 21x79mm link body that aligns with standard NH fuse holders for straightforward replacement.
