Eaton 50A Tag Fuse 51 x 285 mm 3.6kV

This tag fuse provides overcurrent protection for motors and associated circuits in high-voltage installations. Designed for use where a robust backup element is required, it operates in distribution and industrial settings to isolate faults and protect downstream equipment. The device is compliant with recognised standards for high-voltage fusing and is suited to systems using medium-voltage switchgear.

• Rated for 50A operation enabling high current capacity
• Operates at 3.6kV for medium-voltage applications
• Back-up speed characteristic for delayed clearance of transient currents
• Constructed to international electrical standard IEC 60282-1 certification
• British Standard approval supporting UK industrial requirements

• Suitable for motor protection in industrial drive systems
• Ideal for installation in medium-voltage switchgear panels
• Used with protection schemes requiring backup fusing elements
• Can be used for safeguarding high-current feeders in factories

The fuse presents a Compact cylindrical envelope with an overall length of 254mm and a cross-section width of 51mm for compatibility with tag-fuse holders.

The back-up speed delays opening on short transients, allowing upstream protective devices to operate first and enabling selective coordination in multi-tier protection strategies.

It is specified for 3.6 kV systems, suitable for medium-voltage distribution and motor circuits requiring that nominal voltage.

Sectors with high-startup or sustained motor currents, such as manufacturing, processing plants and heavy mechanical workshops, will benefit from the 50A current capability.
