Eaton EBR-3000-2B0LA1 Bus Differential Relay - High Impedance
Part Number: EBR-3000-2B0LA1
Quick Summary
Bus differential relay provides high-impedance protection for power buses in MCCs and main switchgear. Engineers frequently contend with nuisance trips and miscoordination during faults, especially in retrofit or expansion projects. Compliances are product-specific and vary by market; confirm SIL, CE, and IP ratings with the manufacturer. Beyond protection accuracy, its Modbus/DNP3 communications and projection-panel mounting streamline deployment, maintenance, and long-term value. This combination supports faster commissioning, tighter coordination with protection schemes, and scalable expansion, making it suitable for industrial automation environments. Its wide operating temperature range and robust construction ensure reliable performance in harsh industrial settings. The result is faster fault isolation, reduced downtime, and a smoother path to regulatory compliance.
