FAQs
For panel installs, utilize the standard mounting configuration and allocate space for a compact device measuring 8.06 in L, 8.62 in H, and 6.82 in W, weighing 5.82 lb. Take advantage of the 4 DI and 4 DO I/O, plus Ethernet connectivity for IEC 61850 and Modbus TCP. Ensure IDC wiring meets EMC requirements and provide proper rail mounting and cable management to maintain signal integrity.
The EMR-3000-2B1HA0 includes IEC 61850 communication over an Ethernet RJ-45 interface, enabling standardized interoperability with substation and automation networks. Paired with Modbus TCP support, it simplifies integration into existing plant networks, reduces wiring complexity, and supports centralized monitoring and protection logic from a single device.
Yes. The unit supports zone selective interlocking (ZSI) with a dedicated interlocking count and fast fault isolation logic. This feature minimizes electrical disturbance and short-circuit duration in motor groups, improving overall system safety and uptime in critical drives and motor cascades commonly found in process and heavy industry environments.
Verify CE marking and applicable regional standards for your installation, along with safety and environmental certifications relevant to your facility. While compliances are manufacturer-stated, confirm IP rating, SIL readiness for safety-critical circuits, and compatibility with your plant's control architecture to ensure regulatory alignment and safe operation.
The device consolidates protection, metering, and networking in a single module, reducing wiring complexity and panel space. Built-in current protection and metering enable real-time energy monitoring and fault diagnosis, cutting maintenance costs and boosting uptime. Remote diagnostics and compatibility with Eaton's PowerPort-E ecosystem further enhance lifecycle value and return on investment.
