Eaton ETR-5000-2B3KB1 Transformer Relay - 50/60 Hz

Wide input compatibility enables operation from 19-300 Vdc or 40-250 Vac, reducing stocking needs and simplifying retrofits across facilities. This translates to faster commissioning and lower total cost of ownership in transformer protection schemes. The eight digital inputs and nine outputs support complex logic and local signaling, cutting external wiring and accelerating fault isolation in switchgear and power distribution panels. Removable terminals and projection mounting make field service and upgrades straightforward, minimizing downtime during maintenance and retrofits. Two analog inputs and two analog outputs, along with current sensing inputs, improve metering accuracy and fault diagnostics, enabling more accurate protection coordination and condition-based maintenance. I/O options such as Trip Coil Monitor, URTD Interface, IRIG-B, and Modbus over LC fiber Ethernet enhance remote monitoring, time synchronization, and secure communications in harsh industrial environments. A compatible ETR‑4000 base relay streamlines procurement and upgrade paths within Eaton’s protection ecosystem, supporting scalable expansion without major redesigns. Conformal coating and rugged construction boost reliability in challenging environments and reduce field failures, while 50/60 Hz operation ensures compatibility with most regional electrical systems across industrial installations.
