Eaton EMR-3MP0-2A9TB1-1 Motor Relay - IEC61850
Part Number: EMR-3MP0-2A9TB1-1
Quick Summary
Eaton motor relay EMR-3MP0-2A9TB1-1 is a robust motor protection and control device designed for industrial networks. Integrating this unit addresses the common challenge of protocol compatibility and wiring complexity that slows commissioning. It supports IEC 61850 over Ethernet, Modbus or DNP3 via RS-485, and IRIG-B timing, with a projection mount, fixed CT term, and configurable MP term conversion. These features enable scalable protection schemes and easier field deployment. By enabling PowerPort-E monitoring workflows and providing a compact IO stack—4 digital inputs, 4 digital outputs, 1 analog output, plus current sensing at 5 A—this relay helps reduce wiring, simplify maintenance, and lower life-cycle costs while delivering reliable motor protection.
