Eaton motor relay EMR-3000-2B1KB0 - IEC 61850 Fiber
Part Number: EMR-3000-2B1KB0
Quick Summary
Eaton motor relay EMR-3000-2B1KB0 delivers advanced motor control for industrial drives and automation panels. This compact, fiber-enabled relay supports IEC 61850 communications, IRIG-B time synchronization, and URTD interfaces to simplify integration in harsh environments. Engineers face challenges coordinating real-time protection, data metering, and remote diagnostics across multiple devices, often resulting in downtime and costly maintenance. The EMR-3000-2B1KB0 addresses these challenges with four digital inputs and four digital outputs, current protection for 5A/1A phase currents, and conformal coated boards for rugged installations. Its standard mounting and fiber-optic Ethernet compatibility streamline panel design, enable scalable upgrades, and reduce wiring complexity across distributed motor control systems, delivering reliability and faster diagnostics for modern automation facilities.

FAQs
EMR-3000-2B1KB0 is designed for standard mounting in industrial motor control panels. Its compact footprint (8.06 in L × 8.62 in H × 6.82 in W) and conformal-coated circuitry enable installation in harsh environments, while fiber Ethernet connectivity simplifies retrofits and future upgrades without rewiring existing systems.
The unit provides phase current protection for 5A and 1A, supports 50/60 Hz operation, and covers voltage ranges of 19–300 V DC and 40–250 V AC. It also includes current protection and metering to enhance motor protection and energy management in automated facilities.
Yes. With IEC 61850 over fiber Ethernet, IRIG-B timing, URTD interface, and zone selective interlocking, it is well-suited for substation automation and large motor populations where precise timing, fast fault isolation, and robust communications are critical.
IEC 61850 communications over fiber is supported for standardizing interoperability. IRIG-B timing and URTD interface further enhance compatibility in synchronized control systems. For specifics on CE/UL certifications, consult Eaton’s documentation or contact the manufacturer.
Warranty follows Eaton Selling Policy 25-000: one year from installation or 18 months from shipment, whichever occurs first. Technical support and documentation are available through Eaton’s channels, including specification sheets and installation guides.
