FAQs

When installing the ETR-4000-2A1IA1, plan for projection mounting and removable terminals to simplify wiring and future maintenance. The unit supports a wide power range (19–300 Vdc / 40–250 Vac) and provides 8 digital inputs and 9 outputs, enabling flexible placement within control cabinets and alongside existing protection schemes. Verify mounting clearance and ensure proper grounding per site standards.
Yes. The ETR-4000-2A1IA1 includes Modbus compatibility over RS-485 (RTU) and Modbus TCP over Ethernet RJ-45. This enables seamless data exchange with SCADA and DCS platforms, supports remote monitoring, and allows time-stamped event logging through IRIG-B, contributing to tighter operational visibility and faster fault response.
The relay offers differential protection and metering capabilities, current protection options, and Zone Selective Interlocking. It supports differential protection and metering to detect internal faults and monitor transformer health, with zone interlocking to improve selective tripping. These features reduce unplanned outages and enhance system reliability in power distribution.
