FAQs

The ETR-5000-2A1LB0 is designed to retrofit with the base ETR-4000 relay and utilizes eight digital inputs, nine outputs, and two current sensing inputs. It supports Mbus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet, enabling seamless communication with SCADA, protection relays, and control systems while preserving existing wiring and topology. In practice, begin by mapping local I/O to protection functions, configure the fiber link for your network, and verify Modbus/DNP3 endpoints to ensure reliable data exchange.
The relay offers differential protection, current protection and metering, voltage protection and metering, and power protection and metering. With 5A and 1A phase current sensing options and flexible power supply (19-300Vdc, 40-250Vac) at 50/60 Hz, it supports precise fault detection, accurate metering, and rapid trip signaling essential for transformer protection in demanding environments.
Yes, the unit supports conformal coating on circuit boards for improved environmental resilience and uses rugged Ethernet fiber communications to minimize EMI and line noise. Removable terminals and semi-flush mounting simplify field installation and upgrades, helping utilities and industrial sites maintain protection without excessive downtime.
The product lists Compliances as 'Contact Manufacturer,' so regional certifications such as CE, SIL, or IP ratings should be confirmed with Eaton before deployment. This ensures that the relay meets local electrical safety, performance, and environmental requirements for your specific jurisdiction and application.
By consolidating protection functions, increasing I/O density, and enabling fiber-based communications, the relay can reduce wiring, simplify commissioning, and improve fault diagnosis. The ability to retrofit atop the ETR-4000 base with a wide power range and robust metering features typically shortens project timelines and lowers operational risks, delivering measurable uptime and maintenance savings.
