Eaton Tag Fuse, 125A Current Rating, 415V Voltage - 125MJ31-7
This tag fuse provides overcurrent protection for low-voltage distribution systems in industrial and commercial installations. Designed for use where time-delay protection and high interruption capability are required, it operates within three-phase supply environments up to medium-voltage distribution levels and is suited to panel-mounted applications in control and distribution equipment.
Features and Benefits:
• 125A rating delivers consistent overload protection and selectivity
• gU characteristic ensures both fusing and isolation in circuits
• High rupture capacity supports safe clearance of fault currents
• 415V voltage rating enables use on common three-phase supplies
• Conforms to IEC 60269 and BS standards for standardised interchangeability
• gU characteristic ensures both fusing and isolation in circuits
• High rupture capacity supports safe clearance of fault currents
• 415V voltage rating enables use on common three-phase supplies
• Conforms to IEC 60269 and BS standards for standardised interchangeability
Applications
• Suitable for protecting distribution feeders in switchboards
• Ideal for industrial motor-control and drive circuits
• Used with distribution blocks in process automation panels
• Can be used as a replacement for panel-mounted protective links
• Ideal for industrial motor-control and drive circuits
• Used with distribution blocks in process automation panels

What physical form factor should installers expect for fitting?
The device is a tag-style fuse with a Compact tubular element designed for clip or holder mounting within fuse carriers, permitting straightforward removal and replacement.
Are there regulatory or material restrictions relevant to procurement?
It meets CE and RoHS requirements and includes approvals recognised for use in UK and Eurasian markets, supporting regulatory conformity for installations.
How does the product behave under fault conditions?
The component is engineered for Rapid interruption of high short-circuit currents, limiting downstream energy and protecting conductors and equipment during severe faults.
What overall envelope must be allowed for equipment layout?
The assembly has a defined overall length of 160mm and a profile height that accommodates common panel cut-outs and holder space requirements.
Which marking or classification indicates its application scope?
It is classified within the gU application category under IEC 60269, indicating suitability for general-purpose fuse positions in distribution systems.
