FAQs

Installation of the ETR-5000-2A0HB0 should start with verifying supply compatibility and planning the eight digital inputs and nine outputs to match your protection scheme. Use the removable terminals for clean field wiring and follow proper cabling practices for Ethernet-based communications. Position the relay for easy access to URTD/IRIG-B options and ensure 61850 or DNP3/TCP network connectivity is established.
ETR-5000-2A0HB0 supports 61850, Mbus TCP, and DNP3 TCP/UDP over Ethernet RJ45, enabling seamless integration with modern automation architectures. This multi-protocol capability reduces engineering effort by preserving existing interfaces while enabling centralized monitoring and remote control. Pair with compatible SCADA or protection schemes to realize faster fault isolation and improved situational awareness.
Yes. The ETR-5000-2A0HB0 includes zone selective interlocking (ZSI) with two interlocking channels, enabling coordinated tripping across transformer banks. This improves reliability by restricting faults to the affected zone and reducing outage times. Combine ZSI with the relay’s metering and protection features to optimize protection selectivity. It also supports flexible mounting and Ethernet-based remote monitoring to verify interlocking status.
The unit accepts a dual power range of 19-300 Vdc or 40-250 Vac and operates at 50/60 Hz, simplifying installation across diverse sites. It provides eight digital inputs and nine digital outputs, plus two current-sensing inputs, enabling robust protection logic and metering across transformer circuits. Removable terminals and conformal-coated boards enhance field service and reliability in harsh environments.
The Eaton policy provides a one-year warranty from the installation date or eighteen months from shipment, whichever comes first, backing performance and service. For maintenance, consult Eaton's spare parts and service programs to plan firmware updates, diagnostics, and on-site or remote support, ensuring long-term protection reliability and availability for uptime.
