Eaton 40A Tag Fuse 21 x 79 mm 500V

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.

• 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

• 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

It is rated for use on systems up to 500V and intended for AC distribution applications where that voltage is present.

The GG time-delay characteristic allows short-duration inrush currents to pass without opening while still clearing sustained overloads to protect conductors and devices.

The product follows IEC60269-1 and IEC60269-2 requirements and fits DIN43620 physical mounting conventions for NH fuses.

The component uses the NH tag style and a 21x79mm link body that aligns with standard NH fuse holders for straightforward replacement.
