FAQs

Plan for semi-flush mounting and use the removable terminals to simplify wiring. The unit supports eight digital inputs and nine outputs, enabling integrated protection logic without excessive external relays. Ensure proper clearance for maintenance access and align the base relay with the ETR-4000 family for compatibility in mixed protection schemes.
The relay provides Modbus RTU or DNP3 RTU communications over fiber optic ST, enabling secure SCADA integration and remote diagnostics. Connect via fiber to your control center, configure the appropriate protocol in the device, and leverage supported metering and protection counters for event-driven alarms and logs.
Yes. The product is designed to work within Eaton’s transformer protection family and references a base relay ETR-4000. This enables seamless replacement or upgrade paths, leverages shared I/O concepts, and simplifies spare parts management and commissioning in established Eaton protection architectures.
Warranty is 25-000 with coverage of one year from installation or eighteen months from shipment, whichever occurs first. Compliance details are listed by the manufacturer and should be confirmed via Eaton’s official documentation to verify exact standards such as CE or SIL applicability for your installation.
Expect faster, coordinated protection actions with zone interlocking, reduced external wiring, and improved SCADA visibility through fiber-based communications.
