Eaton motor relay EMR-3000-2B1IA0 - Current Protection
Part Number: EMR-3000-2B1IA0
Quick Summary
Eaton motor relay EMR-3000-2B1IA0 provides precise motor control and protection for industrial automation and process lines. This device helps eliminate guesswork by consolidating protection, metering, and communications in a single compact unit. Certification specifics such as CE marking and IP ratings should be confirmed with Eaton for your exact installation, as compliance varies by model. The EMR-3000-2B1IA0 supports Modbus RTU over RS-485 and Modbus TCP over Ethernet, along with current protection and metering, IRIG-B, URTD interface, and zone selective interlocking, enabling scalable control in demanding environments. By integrating these capabilities, you can reduce wiring, shorten installation times, and improve downtime statistics for maintenance teams and project managers.

FAQs
Install on a standard panel footprint (6.82 in wide, 8.06 in deep, 8.62 in high) using the standard mounting method. Wire 4 digital inputs and 4 digital outputs as required, connect Modbus RTU over RS-485 and Modbus TCP over Ethernet for PLC/SCADA integration, and power from 19-300 Vdc or 40-250 Vac. Ensure proper clearance and follow Eaton installation manuals for terminal torque and grounding.
The EMR-3000-2B1IA0 supports Modbus RTU over RS-485 and Modbus TCP over Ethernet. This enables direct integration with most PLCs and SCADA systems without extra adapters. Use RS-485 for fieldbus connections and Ethernet for higher-level supervision, data logging, and remote monitoring, reducing wiring complexity and allowing centralized control.
Yes. The unit includes Zone Selective Interlocking (ZSI) with a dedicated control path to coordinate fast, selective tripping. This minimizes fault impact and improves system availability in motor feeders and distribution networks.
Certification details vary by model and installation. Compliances for EMR-3000-2B1IA0 should be confirmed with Eaton; verify CE marking, IP rating, SIL requirements, and any industry-specific standards before deployment.
Consolidating protection, metering, and comms reduces hardware counts, wiring, and panel space, which lowers installation time and maintenance contacts. Remote diagnostics and data logging support proactive maintenance and energy management, contributing to reduced downtime and improved return on investment.
