FAQs

Begin with the standard mounting compatible with a motor relay. Connect four digital inputs and four digital outputs for basic control and status signaling, and wire the single analog output for feedback. Provide power within the 19–300 VDC or 40–250 VAC range and ensure 50/60 Hz compatibility. Use Ethernet RJ-45 for IEC 61850, Modbus, and DNP3 TCP interfaces, and configure IRIG-B URTD if timing is required. This setup reduces wiring complexity and enables remote monitoring via the control network.
The EMR-3000-2A0HB0 supports 5A and 1A phase currents, with broad voltage ranges of 19–300 VDC and 40–250 VAC, operating at 50/60 Hz. These ratings enable effective current protection and metering for a wide variety of motors, while the IRIG-B interface allows precise timing for coordinated protection schemes. Properly selecting the current setpoints ensures fast fault detection and minimized nuisance trips in production lines.
Yes. The EMR-3000-2A0HB0 provides Ethernet RJ-45 interfaces for IEC 61850, Modbus TCP, and DNP3 TCP, enabling seamless integration with modern substation and plant automation networks. This compatibility supports centralized monitoring, time-synchronized protection, and scalable I/O integration, reducing panel wiring and enabling easier diagnostics and upgrades across control cabinets.
The product data indicates compliances require direct confirmation from the manufacturer. While formal certifications like SIL or CE are not listed in the available specifications, the device offers industry-standard interfaces ( IEC 61850 over Ethernet, IRIG-B, Modbus/DNP3 TCP) and a conformal coating suitable for harsh environments. For formal certification details, contact Eaton or the authorized distributor to obtain the latest compliance documentation.
By consolidating motor control, protection, and metering in a single device with current protection and metering, you can reduce wiring complexity, shorten installation times, and improve fault detection. Remote monitoring through Ethernet interfaces enables predictive maintenance, lowering downtime and extending motor life. The conformal coating further enhances reliability in challenging environments, contributing to a faster return on investment for OEMs and system integrators.
