Flexible power supply range is a core capability, supporting 19-300 VDC and 40-250 VAC, which enables universal deployment across global facilities and simplifies panel design, reducing inventory and commissioning time for transformer protection. The eight digital inputs, two analog inputs, two current-sensing inputs, and nine outputs deliver a rich protection matrix, enabling voltage protection, differential protection, and metering within a single device, lowering total cost of ownership and shortening time-to-protection. Installation is streamlined by removable terminals and projection mounting, which minimizes wiring effort and downtime during retrofits or upgrades, while conformal coated circuit boards boost reliability in harsh environments. Communication options are field-proven with Modbus and DNP3 TCP over LC duplex fiber Ethernet, enabling remote monitoring and coordinated protection without costly copper runs. The I/O options include IRIG-B timing, sensitive ground input, and trip coil monitor for precise protection coordination, making it easier to design and validate zone selective interlocking and fast-break protection. Finally, compatibility with the ETR-4000 base relay provides a clear upgrade path and consistent protection philosophy across the Eaton family, helping maintenance teams standardize spare parts and training.

FAQs

Installation is streamlined by the device's removable terminals and projection mounting, allowing quick field wiring and secure mounting. The unit is compatible with the ETR-4000 base relay, which enables straightforward upgrades without replacing the entire protection scheme. Plan for proper cable routing, verify fiber communication readiness, and follow Eaton's installation guidelines for best results in substations and control rooms.
The relay operates on a wide power range: 19-300 VDC and 40-250 VAC, with a 50/60 Hz frequency rating. This versatility supports installations with mixed DC and AC supplies, reducing the need for multiple protective relays across a single site and helping ensure consistent protection logic across equipment.
ETR-5000-2B2KB1 supports Modbus and DNP3 TCP communications over LC duplex fiber optic Ethernet, enabling robust, low-latency networking between protection devices and control systems. It also includes IRIG-B timing and trip coil monitoring capabilities, which enhance time synchronization and protection coordination in complex protection schemes.
This transformer protection relay is ideal for transformer protection, metering, differential protection, voltage protection, and current protection in substations and large control centers. With 8 digital inputs, 2 analog inputs, 9 outputs, and 2 analog outputs, it supports zone selective interlocking and advanced metering while providing a path to upgrade from ETR-4000 as needs evolve.
Eaton offers a one-year warranty from the date of installation or eighteen months from shipment, whichever occurs first. For compliance certifications such as CE, SIL, and IP ratings, confirm with Eaton directly. Technical support and documentation are available through Eaton’s product pages and regional distributors, with spare parts and retrofit guidance aligned to the ETR-4000 family for upgrade paths.
