Quick Summary

Eaton EMR-3MP0-2A0HB1-1 motor relay is designed for integrated motor protection and control in industrial Ethernet environments. Operators often struggle to harmonize protective relays with modern communication protocols while keeping wiring manageable. Compliances are listed as contact manufacturer, so verify specifics with Eaton; however, the unit supports IEC 61850 over Ethernet, Modbus TCP and DNP3 TCP for seamless substation and plant integration. This combination enables scalable, interoperable control across automation architectures. With 4 digital inputs, 4 digital outputs, 1 analog output, and 5/1A phase current options, this relay delivers quicker fault isolation, reduced wiring complexity, and simpler upgrades. The projection-mount design and MP Terminal Conv compatibility further streamline field installation and long-term reliability.

FAQs

Follow Eaton’s MP-3000 to EMR-3MP0 installation instructions, using the MP Terminal Conv for wiring and the projection-mount fit for installation. Connect 4 digital inputs, 4 digital outputs, and 1 analog output as required by your motor protection scheme. Configure communication addresses for IEC 61850, Modbus TCP or DNP3 TCP, and ensure proper 50/60 Hz operation. This setup reduces wiring complexity and accelerates commissioning in controlled environments.
Key specs include 5A or 1A phase current ratings, 4I/4O digital I/O, 1AO analog output, and 50/60 Hz frequency. The unit provides current protection and metering inputs to support reliable protection decisions. It also supports IRIG-B timing and Ethernet-based communication (IEC 61850, Modbus TCP, DNP3 TCP), enabling seamless integration with PLCs and SCADA systems.
Yes, the EMR-3MP0-2A0HB1-1 is designed for industrial motor control with projection mounting and protective features. While conformal coating and mounting robustness aid reliability, confirm environmental ratings and any ruggedization requirements directly with Eaton for your exact site conditions. Its modular I/O and Ethernet communications support scalable, fault-tolerant control in challenging facilities.
The product data indicates compliances require manufacturer confirmation. To meet regulatory requirements, verify with Eaton whether CE, SIL, IP ratings, or other certifications are applicable to your region and application. While IEC 61850, Modbus TCP, and DNP3 TCP are supported, explicit certification stamping should be confirmed before procurement for mission-critical installs.
The integrated protection and multi-protocol communications reduce field wiring, shorten commissioning times, and simplify diagnostics, contributing to lower installation and maintenance costs. With built-in current protection and metering, operators gain better fault isolation and energy usage visibility, improving uptime and long-term system reliability in continuous-process environments.
