Eaton Tag Fuse, 20A Current Rating, 415V Voltage - 20MJ31-8


This tag fuse is designed to protect electrical circuits in industrial installations by interrupting fault currents and preventing equipment damage. It is intended for use in systems operating at standard industrial voltages and in environments requiring high interrupting capability. The product conforms to recognised European and British standards and is suitable for applications where a robust, replaceable fuse element is needed.

Features and Benefits:


• 20A current rating for defined overcurrent protection
• gU operating characteristic for general-purpose interruption
• High rupture capacity to clear high fault currents safely
• Rated at 415V for common three-phase systems
• Complies with IEC 60269 to match industry protection protocols

Applications


• Suitable for motor protection in manufacturing plants
• Ideal for distribution boards in commercial installations
• Used with control panels in automation systems
• Can be used for protection of transformers and feeders

What physical form factor should I allow for installation?


The fuse uses a tag-style mount with an overall length of 160mm, requiring clearance for the tag connection and replacement access.

Which standards ensure it meets European and British requirements?


It is produced to meet IEC 60269 and carries approvals aligned with British and CE conformity frameworks as well as RoHS material restrictions.

How does the fuse speed affect coordination with downstream devices?


The gU characteristic provides a general-purpose time–current response suitable for coordination where a balance of fast clearing and selectivity is required.

Is this suitable for use where high fault levels are present?


Yes, the high rupture capacity rating means it is capable of interrupting substantial fault currents commonly encountered in industrial networks.

What physical footprint should be expected for panel layout planning?


The fuse element size is 31 x 131mm, which determines the holder and panel cut-out dimensions needed for installation.
