Feature → Business Impact → Application: Profibus-DP over D-SUB / RS485 enables reliable fieldbus communication, reducing commissioning time and enabling centralized protection management across assemblies. This translates to faster fault isolation, improved MTBF through coordinated protection, and lower lifecycle costs in switchgear and transformer installations. Feature → Business Impact → Application: 19-300 Vdc / 40-250 Vac power supply range supports diverse plant voltages, enabling a single unit to cover multiple feeders and locations while reducing inventory. Application: transformer protection in substations and distribution panels where voltage diversity is common. Feature → Business Impact → Application: 8 digital inputs and 9 outputs, plus Zone Selective Interlocking (2), provide granular control and selective tripping, improving system availability and reducing arc-flash risk in high-density switchgear. Application: IEC/UL-compliant protection schemes in industrial facilities with mixed gear. Feature → Business Impact → Application: IRIG-B interface, Sensitive Ground Input, and Trip Coil Monitor offer precise synchronization and monitoring, boosting diagnostics and reducing unplanned outages in critical processes. Application: power-marming and peaking transformer protection in energy-intensive industries. Feature → Business Impact → Application: Removable terminals and semi-flush mounting simplify field installation, enable a cleaner panel layout, and speed up retrofit projects in OEM or refurbishment programs. Application: retrofit or upgrade of legacy transformer protection relays without large cabinet rework.

FAQs

The ETR-5000-2A1EA0 supports Profibus-DP over RS485 via D-SUB, enabling integrity in fieldbus communications and straightforward integration with existing PLCs and HMIs. This compatibility reduces commissioning time and minimizes wiring errors by consolidating protection signals and diagnostics on a common network.
It offers protection and metering across multiple protection domains including current protection, differential protection, power protection, and voltage protection. With eight digital inputs, nine outputs, and zone selective interlocking, it supports selective tripping and precise fault localization for transformer circuits.
Yes. The unit includes Zone Selective Interlocking (2), enabling coordinated protection sequencing across feeders and transformers. This reduces disturbance to unaffected sections and improves overall system reliability in high-density switchgear environments.
The relay features removable terminals and semi-flush mounting, simplifying field wiring and panel integration. It supports a broad input range (19–300 Vdc, 40–250 Vac) and 50/60 Hz operation, making it adaptable for mixed-voltage installations and retrofit projects without extensive cabinet redesign.
Eaton provides a standard warranty as per policy 25-000, typically offering one year from installation or eighteen months from shipment, whichever occurs first. For compliance and certification specifics, customers should contact Eaton directly to confirm current coverage and any region-specific requirements.
