Eaton Tag Fuse, 450A Current Rating, 415V Voltage - 450RJ31-7
This tag fuse provides overcurrent protection for feeder pillars and distribution equipment in industrial electrical systems. It is designed for use with three-phase 415V networks and combines a high continuous current rating with rapid-operation characteristics suitable for protecting feeders and main distribution circuits. The product conforms to recognised international and regional standards and is manufactured to meet electrical installation requirements.
Features and Benefits:
• 450A continuous current rating delivers high-capacity protection
• gU fuse characteristic ensures reliable full-range clearing
• High rupture capacity limits fault energy during short circuits
• 49 x 131mm fuse body fits standard tag fuse holders
• RoHS compliance reduces hazardous-substance concerns
• BS and IEC 60269 conformity supports regulatory installation needs
• gU fuse characteristic ensures reliable full-range clearing
• High rupture capacity limits fault energy during short circuits
• 49 x 131mm fuse body fits standard tag fuse holders
• RoHS compliance reduces hazardous-substance concerns
• BS and IEC 60269 conformity supports regulatory installation needs
Applications
• Suitable for feeder pillar protection on utility and industrial sites
• Ideal for main distribution panels in commercial buildings
• Used for protecting incoming supplies to motor control centres
• Can be used as a replacement for high-capacity fuses in switchgear

What voltage systems is it intended to protect?
It is specified for use on 415V installations typically found in three-phase distribution networks.
How does the fuse manage large fault currents?
The construction provides high rupture capacity to interrupt significant short-circuit currents safely.
What marking or approvals indicate standards compliance?
It carries markings aligned with BS, CE and EAC requirements and is manufactured to IEC 60269 standards.
Are there constraints on the fuse speed class for selective coordination?
The gU speed characteristic offers full-range protection, suitable where both overload and short-circuit clearing are required.
What installation form factor should installers expect?
The unit uses a Compact tag fuse form with a 49 x 131mm fuse element suited to tag fuse holders.
