Eaton EMR-3000-2B0KA1 Motor Relay - fiber Ethernet
Part Number: EMR-3000-2B0KA1
Quick Summary
Eaton motor relay EMR-3000-2B0KA1 provides smart motor control for industrial drives and automation panels. Engineers often struggle to reliably protect, monitor, and network motor circuits within compact enclosures and tight installation schedules. While specific certifications aren’t listed, the device supports IEC 61850 over LC duplex fiber optic Ethernet, IRIG-B interfaces, and zone-selective interlocking, which align with modern plant standards. In practice, 4 digital I/O and up to 5A/1A phase current handling enable precise protection and flexible control. This combination delivers safer startups, reduced downtime, and improved visibility in industrial automation environments. Designed for installation in control panels and networked drives, it supports scalable I/O and future-proof integration.

FAQs
EMR-3000-2B0KA1 is designed for panel mounting with projection mounting as a straightforward retrofit. Ensure the 4 digital I/O is wired to your controller, connect the fiber optic Ethernet links for IEC 61850/Modbus-DNP3 traffic, and align IRIG-B timing if used. Verify voltage ranges (19-300 V DC, 40-250 V AC) and protective settings before commissioning.
The relay handles 5A and 1A phase currents with 50/60 Hz operation, and provides current protection and metering alongside 4 digital I/O lines. These specs enable precise motor protection, energy monitoring, and rapid fault signaling to the PLC or SCADA system, reducing nuisance trips and enabling better troubleshooting in automated drives.
Yes. The device supports IEC 61850 and Modbus/DNP3 TCP over LC duplex fiber optic Ethernet, enabling seamless integration into substation architectures and plant networks. This reduces integration risk, improves data availability, and simplifies commissioning in large-scale automation environments.
Compliance details are listed as 'Contact Manufacturer' in the data set. While explicit certifications aren’t published here, the product includes IEC 61850 compatibility, IRIG-B interfaces, and zone selective interlocking. For formal certifications (CE, SIL, IP), please confirm with Eaton or your Eaton distributor before procurement.
The relay combines monitoring, protection, and networked communication in a single device, reducing wiring complexity and panel space. Benefits include lower installation costs, faster fault isolation via precise metering, and extended uptime through robust networking capabilities. The one-year (or 18 months from shipment) Eaton warranty also helps mitigate maintenance risk.
