Feature → Business Impact → Application: The EBR-3000-2B0DB0 delivers bus differential protection for feeders, reducing nuisance trips and improving system reliability in critical manufacturing lines and utility feeders. This translates to lower unplanned downtime and safer fault isolation in mixed-load environments, especially where feeder redundancy is key. Application: medium to large industrial facilities seeking dependable feeder protection with clear fault isolation. Feature → Business Impact → Application: A power supply range of 19-300 Vdc / 40-250 Vac supports diverse plant power architectures, enabling seamless retrofits and multi-source environments. This reduces wiring changes and speeds commissioning, ideal for retrofit projects or expanding lines without a full control-system overhaul. Feature → Business Impact → Application: Profibus-DP with a fiber optics interface (ST connector) enables reliable, high-speed communication to PLCs and SCADA, enhancing network integration, diagnostics, and remote fault analysis. Application: control-room monitoring and distributed protection schemes in process facilities. Feature → Business Impact → Application: Eight digital inputs, six digital outputs, and one current sensing input provide flexible I/O for status signaling and control interlocks, simplifying wiring and maintenance. Application: feeder protection in compact substations or cabinet-based protections. Feature → Business Impact → Application: Conformal coating and removable terminals improve environmental resilience and field serviceability, reducing maintenance time and extending product life in harsh industrial settings. Application: dusty, humid, or temperature-variable environments common to manufacturing floors, mines, and water treatment plants. Feature → Business Impact → Application: A compact footprint with standard mounting and a 10 W / 17 VA burden supports easy integration into existing panel layouts without excessive heat or power draw. Application: upgrade projects with limited space and existing bus-protection schemes.

FAQs
This relay uses a standard mounting method with removable terminals, supporting straightforward installation in typical Eaton or compatible electrical panels. Its 8 digital inputs, 6 digital outputs, and single current-sensing input align with common feeder protection schemes, enabling a clean retrofit or new build without extensive panel redesign.
Key specs include a power supply range of 19-300 Vdc or 40-250 Vac, a 5 A contact rating, 50/60 Hz operation, and a burden of 10 W / 17 VA. It supports 8 DI, 6 DO, and 1 current sense input, with a temperature range from -20 to 60°C, making it suitable for typical plant environments.
Yes. The device is designed for feeder protection with banked protection logic, Profibus-DP communication, and conformal coating for reliability in industrial settings. It offers adequate current rating, input/output count, and a compact form factor to fit in standard control panels used in medium-scale manufacturing, water treatment, and process industries.
Certification details such as SIL, CE, or IP ratings are not listed in the provided data. For regulatory compliance, verify the exact certifications with Eaton or your regional distributor before deployment in safety-critical applications.
The product warranty follows Eaton's policy: one year from installation or eighteen months from shipment, whichever occurs first. This warranty reduces risk and maintenance costs, supporting a lower total cost of ownership when paired with improved uptime and reduced nuisance trips from robust feeder protection.
