Quick Summary

Eaton motor relay EMR-3MP0-2A0HB1 protects motors and enables remote control in industrial automation environments. This compact protection and control relay addresses common pain points around wiring complexity, PLC integration, and field diagnostics by consolidating protection, communication, and status reporting in a single device. Compliance requirements vary by configuration, with CE marking and other safety certifications typically addressed per variant; verify with Eaton for SIL, IP ratings, and related standards. The solution leverages IEC 61850 over Ethernet RJ-45, Modbus TCP or DNP3 TCP/UDP, and IRIG-B interfaces, while offering projection mounting for straightforward panel deployment. For engineers and maintenance teams, this translates to faster commissioning, easier maintenance, and scalable I/O for growing motor fleets.

FAQs

The EMR-3MP0-2A0HB1 supports IEC 61850 over Ethernet RJ-45, enabling standardized communication with SCADA and substation automation systems. This compatibility simplifies integration with modern control architectures, reduces custom middleware requirements, and improves interoperability across vendors. For specific device profiles and server/client roles, refer to the Eaton EMR-3MP0 documentation and your network design.
The device provides 4 digital inputs, 4 digital outputs, and 1 analog output, with analog inputs set to 0. It supports current protection and metering sensing inputs, and phase currents of 5A and 1A, enabling local status, fault signaling, and metering data to be fed into protection logic or a supervisory system. This configuration reduces auxiliary modules and simplifies panel wiring for motor protection schemes.
Yes. The EMR-3MP0-2A0HB1 lists a broad input voltage range including 19–300 Vdc and 40–250 Vac, making it adaptable to mixed-voltage motor fleets and retrofit scenarios. This flexibility supports phased migrations in facilities that operate legacy drives alongside newer intelligent relays, reducing downtime during upgrades.
Compliance is configuration-dependent; Compliances shows 'Contact Manufacturer' for this model. Typical practice includes CE marking and other safety certifications aligned to regional requirements. Always confirm the exact certification set with Eaton based on your region, application, and the control system architecture before procurement and installation.
By consolidating protection, communication, and diagnostics in a single device, the EMR-3MP0-2A0HB1 reduces wiring complexity, accelerates commissioning, and minimizes field faults. This leads to lower maintenance labor, shorter downtime during faults, and better lifecycle data for energy management. In high-motor-density plants, the ROI scales with reduced panel space, fewer spare parts, and improved protection reliability.
