Eaton EBR-3000-2B0CB1 Bus Diff Relay - High Impedance
Part Number: EBR-3000-2B0CB1
Quick Summary
The Eaton Bus differential relay EBR-3000-2B0CB1 provides high impedance protection for bus sections in electrical substations. Engineers often struggle with nuisance trips and miscoordination across protection schemes during fault events. Industry-standard requirements such as CE-style compliance, SIL safety concepts, and rugged IP-rated housings influence selection and lifecycle risk. Beyond protection accuracy, the EBR-3000-2B0CB1 offers MODBUS/DNP3 communications, conformal coating, and a projection-panel installation option to simplify integration and reduce field commissioning time. Inline with Eaton’s warranty policy, this device is designed for reliable long-term operation in challenging environments. End user teams gain confidence from clear diagnostics and standardized interfaces, accelerating project timelines and minimizing downtime. This combination supports 50/60 Hz systems and robust field deployment in challenging environments.

Selling Policy 25-000 - Distribution and Control Products and Services
High impedance bus differential relay design provides precise fault detection with reduced mis-operation, enabling improved system reliability and minimizing unplanned downtime in substations and switchgear. This feature accelerates fault isolation and enhances protection coordination, essential for utilities and industrial plants operating complex feeder networks. The EBR-3000-2B0CB1 is designed for 50/60 Hz environments, making it suitable for a wide range of regional grids and industrial installations. MODBUS/DNP3 communications via RJ45 delivers remote monitoring, SCADA integration, and rapid fault analysis, reducing现场调试时间 and enabling centralized diagnostics across distributed protection schemes. Conformal coating protects the unit in damp, dusty, or chemically challenging environments, extending service life and lowering maintenance costs. Projection-panel mounting and a compact footprint simplify retrofit and panel-board installations, cutting commissioning time and minimizing panel space. With a 5 A contact rating and 10 W / 17 VA burden, the relay delivers reliable control signaling while keeping power consumption and heat dissipation in check. These attributes collectively support faster project schedules, lower total cost of ownership, and dependable protection in both utilities and industrial facilities.
