Eaton EBR-3000-2B0DB1 Bus differential relay - Profibus-DP
Part Number: EBR-3000-2B0DB1
Quick Summary
The Eaton Bus differential relay EBR-3000-2B0DB1 is designed to deliver fast, reliable feeder protection for switchgear and distribution panels. Engineers often struggle with nuisance tripping and limited diagnostic visibility in dynamic electrical networks, which can degrade uptime and increase maintenance costs. While many installations rely on generic protection relays, the EBR-3000-2B0DB1 provides precise differential sensing and robust communication to constrain outages and accelerate fault isolation. Certifications you’ll frequently encounter for bus relays include CE marking, SIL compatibility, and IP protection variants depending on configuration and region; always verify with Eaton’s datasheet for your exact model. In practice, this device supports seamless integration with Profibus-DP, enabling clear data exchange and improved protection coordination in modern control architectures.

The EBR-3000-2B0DB1 offers a broad power supply range and flexible I/O that simplify multi-volt/multi-region installations. This feature reduces wiring complexity and stock diversity, delivering measurable business value through faster project commissioning and lower maintenance costs as feeder protection can be deployed with a single device across sites. With 8 digital inputs and 6 digital outputs, the relay supports comprehensive monitoring and control of feeder status, alarms, and interlocks, directly improving system availability and operator awareness in control rooms and panels. The built-in Profibus-DP communication, including a fiber optics interface with an ST connector, enables reliable, high-speed data exchange for protection coordination, diagnostics, and remote configuration—minimizing commissioning time and improving change-management efficiency. The unit is designed for projection panel mounting and uses removable terminals, which streamline installation, service, and field retrofits in crowded panels. A quick-care wiring approach reduces field errors, while conformity to Conformal Coated Circuit Boards protects electronics in challenging environments, extending product life in harsh industries. With a burden of 10 W / 17 VA and a 5 A contact rating on AC/DC outputs, the EBR-3000-2B0DB1 delivers efficient protection without excessive power draw, supporting energy-conscious design in modern switchgear. The device supports -20° to 60°C ambient temperatures, offering reliability in workshops, plants, and outdoor enclosures where temperature variation is common. In short, this relay aligns with industry practices for feeder protection, panel integration, and Profibus-DP networks, helping engineers meet tight project timelines and regulatory expectations.
