FAQs
Installing the EMR-3000-2B1KB1 starts with verifying the panel space for projection mounting and routing the LC fiber optic cables to the IEC 61850 and Modbus/DNP3 ports. Attach the device per Eaton guidelines, connect the four digital inputs and outputs, and configure current protection setpoints for 5A and 1A phases. Proper grounding and IRIG-B / URTD interfaces should be wired as specified.
EMR-3000-2B1KB1 supports IEC 61850 over LC duplex fiber optic Ethernet and Modbus/DNP3 TCP, enabling interoperable communication with modern substations and PLCs. IRIG-B and URTD interface options add time synchronization and ground reference flexibility, while four digital I/O lines support local signaling and interlocking. This combination reduces integration risk in mixed automation environments.
Yes, with Zone Selective Interlocking enabled and four digital I/O lines, this motor relay coordinates protection with feeder relays and breakers, improving selective fault isolation. The 5A/1A current protection and metering provide real-time data to SCADA or protection schemes, enabling faster fault clearance and reduced system stress in motor-driven processes.
Current protection and metering are built in, with distinct phase currents of 5A and 1A supported by four digital inputs and outputs for signaling. The device also supports fiber optic communication to minimize EMI. Additional safety features include conformal coated circuit boards and projection mounting for rugged industrial environments.
Dimensions are 8.06 in long, 8.62 in high, and 6.82 in wide, with a weight of 5.82 lb. Projection mounting supports compact panel fits, and conformal coating improves reliability in harsh environments. Warranty is one year from installation or eighteen months from shipment, whichever occurs first, with Eaton's standard policy.
