FAQs
Install the relay on a projection panel with removable terminals for quick wiring and safer field service. Ensure the device is mounted in a ventilated enclosure suitable for -20 to 60°C, connect the eight digital inputs, six outputs, and one current-sensing input as per the control scheme, and route communication through the Profibus-DP interface for PLC integration.
It provides eight digital inputs, six digital outputs, and one current-sensing input, with a contact rating of 5 A AC/DC. The unit supports a wide power range (19-300 Vdc, 40-250 Vac) and has a burden of 10 W / 17 VA, enabling flexible protection logic while maintaining efficient performance.
Yes, the EBR-3000 uses Profibus-DP over a fiber optics interface with an ST connector. This delivers noise immunity, reliable fieldbus performance in electrically noisy environments, easier long-distance wiring, and straightforward PLC integration for coordinated feeder protection schemes.
Ideal for feeder protection in industrial plants and substations, especially where reliable bus differential protection and fiber optic communication are advantageous. Its 8/6 I/O, wide voltage ranges, and panel-mount design support scalable protection schemes across manufacturing floors and power distribution networks.
The product follows Eaton’s standard warranty policy: one year from installation or 18 months from shipment, whichever occurs first. Compliance details are provided by the manufacturer, and regional approvals such as CE or UL should be confirmed with Eaton to meet local regulatory requirements.
