FAQs

The ETR-5000-2A1CB0 uses removable terminals to simplify field wiring and future maintenance. It supports semi-flush mounting for compact installations and ease of retrofit with the existing ETR-4000 base relay. Plan for secure conductor terminations and verify proper torque per manufacturer guidance to minimize termination failures in harsh environments.
This model provides eight digital inputs and nine outputs for comprehensive protection and metering logic, along with power supply flexibility (19-300Vdc, 40-250Vac) and 50/60 Hz compatibility. It combines differential, power, and voltage protection concepts with modular I/O to coordinate protection schemes and reduce nuisance trips.
Use the built-in Modbus TCP or DNP3 TCP/UDP over Ethernet RJ45 interfaces to connect to SCADA. This enables straightforward data collection, event reporting, and remote control. Ensure network security measures are in place, including access controls and proper PLC/RTU addressing schemes, to safeguard protection data.
Compliance details for the ETR-5000-2A1CB0 should be confirmed with Eaton, as the product page lists Compliances as 'Contact Manufacturer.' When planning procurement, request the latest certificates (CE, SIL, IP ratings, etc.) and ensure site-specific regulatory requirements are met before installation.
The relay’s modular IO, Ethernet connectivity, and robust protection features reduce engineering time and field wiring complexity, leading to faster commissioning and lower maintenance costs. The inclusion of a 1-year warranty and the ability to reuse the ETR-4000 base relay support long-term asset utilization and predictable total cost of ownership.
