Eaton 80A Fuse 79 mm x 51 mm x 21 mm 690V

This fuse is a blade-style protective device designed for industrial electrical systems, providing overcurrent interruption for power circuits operating at elevated voltages. It is intended for use where fast action against short-circuit events is required, offering compatibility with blade-mounted fuseholders and installations that demand a robust, replaceable protective element.

• 80A rating delivers consistent current protection for heavy loads
• aR characteristic isolates short-circuit faults rapidly
• T-speed operation minimises thermal stress during transient faults
• High rupture capacity enables safe disconnection under fault energy
• 690V voltage class supports high-voltage power distribution
• 15mm tag width allows secure blade termination and handling

• Suitable for industrial motor control panels requiring fast-clearing fuses
• Ideal for distribution boards in automation and plant equipment
• Used with blade fuseholders in power-conversion modules
• Can be used for protection of switchgear feeding multiple loads

The construction incorporates elements rated for high rupture capacity to withstand and safely interrupt the thermal and mechanical stresses of large fault currents.

Its fast-acting aR characteristic provides minimal time-delay clearing, enabling predictable selective coordination when paired with appropriately rated upstream devices.

The blade format concentrates the connection into a standardised tag width, facilitating insertion into Compact fuseholders while maintaining secure electrical contact.

It holds multiple standards approvals indicating conformity with established international safety and performance criteria.
