Eaton Tag Fuse, 4A Current Rating, 550V Voltage - NITD4
This tag fuse is a blade-equipped protective component intended for general industrial applications where controlled overcurrent interruption is required. It functions as a line protection device compatible with switchgear and fuse holders, offering a standard-safe solution for circuits up to medium voltage levels in industrial electrical systems.
Features and Benefits:
• Rated current 4A enabling precise circuit protection
• gG/gL characteristic for comprehensive overload and short-circuit protection
• Voltage capability 550V supporting higher-voltage installations
• Offset bladed tag for secure mounting and straightforward connection
• Complies with BS88 and IEC 60269-2 for standardised performance
• RoHS compliant reducing hazardous substance use
• gG/gL characteristic for comprehensive overload and short-circuit protection
• Voltage capability 550V supporting higher-voltage installations
• Offset bladed tag for secure mounting and straightforward connection
• Complies with BS88 and IEC 60269-2 for standardised performance
• RoHS compliant reducing hazardous substance use
Applications
• Suitable for protecting motor control circuits in automation panels
• Ideal for distribution boards in manufacturing facilities
• Used with fuse holders in switchgear assemblies for industrial sites
• Can be used for safeguarding control transformers and auxiliary supplies

What physical form factor does it use and how does that affect installation?
It adopts a 14 x 55mm cylindrical fuse link with an offset bladed tag, permitting installation in compatible 14mm fuse clips and providing clearance for tag-style fuse holders.
How does the fuse characteristic influence protective behaviour during faults?
The gG/gL curve indicates that it will interrupt both overloads and high-current faults, offering full-range protection rather than protection limited to specific fault types.
What standards ensure its suitability for industrial systems?
It meets BS88 and IEC 60269-2 specifications and carries a CE marking, indicating conformity with those recognised performance and safety criteria.
Are there constraints on the environments where it can be applied electrically?
The 550V rating defines the maximum system voltage for safe operation, it should be used only in circuits at or below this voltage.
