Eaton EBR-3Z-2B0DB0-B Bus Differential Relay, 5A

Part number EBR-3Z-2B0DB0-B (EBR-3000 series) is an Eaton bus differential relay providing high‑impedance, three‑phase differential protection. With a wide auxiliary supply range of 40–250 Vac or 19–300 Vdc and a 5 A AC/DC output, this protection relay is intended for selective bus, transformer, generator and motor differential schemes. The panel‑mount unit simplifies integration into protection panels and offers reliable operation on 50/60 Hz systems.

Key Features

• Three‑phase high‑impedance differential protection engineered for bus and feeder protection in switchgear.
• Wide auxiliary supply compatibility: 40–250 Vac or 19–300 Vdc to suit various control systems.
• 5 A AC/DC output suitable to drive trip coils and downstream protection circuitry with reliable operation.
• Low power draw (10 W / 17 VA) and 50/60 Hz frequency compatibility for international installations.
• Panel‑mount design with removable connector simplifies installation, maintenance and module replacement.
• Robust environmental range (−20° to 60°C) and high‑impedance algorithm to reduce nuisance trips from CT mismatch or external faults.

Technical Specifications

Applications

Used for bus differential schemes in medium/high‑voltage switchgear, transformer and generator differential protection, motor bus protection, and restricted earth‑fault detection on grounded‑wye windings in industrial and utility installations.
