Eaton Tag Fuse, 250A Current Rating, 400V Voltage - 250NHG03B-400 NH FUSE 250A 400V GG/GL SIZE 03
This tag fuse is a high-capacity protective device designed for low-voltage power systems, providing overcurrent interruption in industrial and renewable-energy installations. It operates at a 400V rating and is intended for use where robust short-circuit performance and standardised NH cartridge integration are required.
Features and Benefits:
• 250A current rating for sustained load protection
• gL fuse speed for comprehensive line protection
• High rupture capacity to withstand severe fault currents
• 150mm overall length for standard NH mounting
• 54mm width to fit NH size 03 holders
• gL fuse speed for comprehensive line protection
• High rupture capacity to withstand severe fault currents
• 150mm overall length for standard NH mounting
• 54mm width to fit NH size 03 holders
Applications
• Suitable for wind turbine electrical protection panels
• Ideal for solar inverter and array protection circuits
• Used with industrial distribution switchgear
• Can be used for utilities power distribution feeders
• Ideal for solar inverter and array protection circuits
• Used with industrial distribution switchgear
• Can be used for utilities power distribution feeders
What electrical standard of breaking capability does it provide?
It offers high rupture capacity suitable for interrupting substantial fault currents in distribution networks.
Which physical form factor does it adopt for system integration?
The device follows the NH cartridge format with size 03 dimensions for compatibility with corresponding holders and fuse bases.
How does the fuse speed affect protection behaviour?
The gL characteristic provides general-purpose, full-range protection, allowing both overload clearing and short-circuit interruption across conductors and equipment.
What approvals support its environmental and safety conformity?
It carries RoHS and CE approvals indicating compliance with restricted substances and applicable EU directives.
