The Eaton EBR-3Z-2B0IB1-B is a bus differential relay combining the 3000 High‑Impedance and EBR‑Z high‑impedance modules in a common bezel. Designed for high‑impedance differential protection, it supports three‑phase bus differential schemes and restricted earth‑fault detection, with MODBUS/DNP3 (RS485 or RJ45) communications and a 10.4 kJ rating for system stability. Ideal for switchgear, transformer, generator and motor protection in industrial and utility installations.

Key Features

High‑impedance differential protection for sensitive and secure bus protection schemes.
Combined 3000 and EBR‑Z modules packaged in a single bezel for compact retrofit.
Three‑phase differential protection suitable for switchgear, transformers, generators and motors.
Restricted earth‑fault protection for grounded‑wye or balanced earth‑fault applications.
MODBUS and DNP3 communications via RS‑485 or RJ45 for SCADA integration.
Conformal coating and projection mount for improved environmental resistance.
