Eaton ETR-4000-2A0LA1 Transformer Relay - 50/60 Hz

Feature → Business Impact → Application: The ETR-4000-2A0LA1 delivers multi‑protocol communications with Mbus TCP or DNP3 TCP/UDP over LC duplex fiber optic ENet, enabling secure, high‑speed data exchange and easier integration with modern SCADA systems. This reduces fault‑diagnosis time and supports centralized protection logic for transformer networks in substations and data centers. Feature → Business Impact → Application: Eight digital inputs and nine digital outputs paired with two current sensing inputs provide a flexible protection and metering interface, enabling customized protection schemes and real‑time status reporting for critical transformers in manufacturing plants and utility corridors. Feature → Business Impact → Application: A wide power‑supply range—19–300 Vdc and 40–250 Vac—together with 50/60 Hz operation and removable terminals in a projection mount, simplifies retrofit projects and new installations, reducing cabinet space concerns and wiring complexity in control rooms and switchgear assemblies. Feature → Business Impact → Application: I/O options such as IRIG‑B, Trip Coil Monitor, and URTD Interface, plus zone selective interlocking (2), enhance coordination and fault isolation, enabling faster restoration and improved system reliability in distributed generation facilities and substations. Feature → Business Impact → Application: The unit’s robust physical design, combined with Eaton’s warranty and service policies, supports a lower total cost of ownership by simplifying maintenance planning and long‑term asset protection across multi‑site deployments.
