Selling Policy 25-000 - Distribution and Control Products and Services
The EMR-3000-2A0KA1 offers high phase current flexibility with 5A and 1A ratings, enabling direct motor protection for a wide range of loads and reducing the need for additional protective devices. This translates to lower panel complexity and faster commissioning in process lines and packaging equipment. The device provides rich I/O—four digital inputs, four digital outputs, and one analog output—delivering precise signaling and control with minimal wiring, improving fault detection and response times for manufacturing lines. Its I/O options include IRIG-B and URTD interfaces, plus fiber-based IEC 61850 and Modbus/DNP3 TCP communication, enabling interoperable integration with substation and plant networks while simplifying remote diagnostics. Broad voltage and frequency support (19–300 VDC, 40–250 VAC, 50/60 Hz) ensures compatibility with mixed drive systems and retrofit projects, reducing the need for multiple relay types. Projection mounting and a compact footprint (8.06 in L, 8.62 in H, 6.82 in W) streamline installation in tight panels and control cabinets, while a 5.82 lb weight supports sturdy mounting. A one-year Eaton warranty and official policy coverage further reduce lifecycle risk, supporting predictable maintenance budgeting and service planning. The product’s emphasis on current protection and metering delivers measurable efficiency gains and improved asset visibility for OEMs and end users alike.

FAQs
This Eaton motor relay uses a projection mounting method and has compact overall dimensions (8.06 in L x 8.62 in H x 6.82 in W) with a weight of 5.82 lb. Ensure mounting space in the control cabinet allows proper ventilation and access to the IRIG-B URTD interface and fiber optic connections. Coordinate with existing panel wiring to leverage the four digital inputs and four digital outputs for streamlined control logic, reducing overall wiring complexity.
Key specs include phase current options of 5A and 1A, voltage ranges of 19–300 VDC and 40–250 VAC, and operation at 50/60 Hz. The device supports Ethernet-based communications over LC duplex fiber, enabling IEC 61850 and Modbus/DNP3 TCP networking. These parameters guide compatibility with your drive and motor architecture and help determine if a single relay can replace multiple legacy devices.
Yes. The EMR-3000-2A0KA1 supports IEC 61850 and Modbus/DNP3 TCP over LC duplex fiber optic Ethernet, enabling standardized, interoperable communication across substations and plant networks. This facilitates remote monitoring, metering, and protection signaling from a single relay, reducing integration time and enabling seamless data exchange with upstream SCADA or control systems.
Compliances are listed as Contact Manufacturer, so confirm CE/SIL/IP ratings with Eaton directly for your regulatory needs. The product comes with Eaton’s warranty policy 25-000, offering one year from installation or eighteen months from shipment, whichever comes first. This provides a predictable support window for maintenance planning and parts availability.
The relay consolidates protection, metering, and multi-protocol communication in a single unit, reducing wiring, panel space, and installation time. With integrated current protection and fiber Ethernet connectivity, you gain faster fault isolation, improved downtime metrics, and deeper asset visibility, supporting data-driven maintenance and lower total cost of ownership over the motor fleet.
