FAQs

Plan for semi-flush mounting and use the removable terminals to ease wiring. Verify the power supply range (19-300VDC or 40-250VAC) matches your plant rails, and ensure compatible communication cabling for Mbus TCP or DNP3 TCP/UDP over LC duplex fiber. Follow Eaton’s wiring diagrams and perform a staged commissioning to validate inputs and outputs before full-load operation.
The device provides eight digital inputs, nine digital outputs, and two current-sensing inputs. It supports a dual power supply range of 19-300 VDC or 40-250 VAC and operates at 50/60 Hz. Communication options include Mbus TCP or DNP3 TCP/UDP over LC duplex fiber, enabling robust SCADA interoperability.
Yes. Its eight-input, nine-output I/O, differential/current protection, and zone selective interlocking support precise protection coordination. The fiber-based Ethernet communications improve remote monitoring and integration with centralized protection schemes, making it appropriate for mission-critical data centers and high-availability manufacturing environments.
Compliance details are listed in Eaton’s official datasheet. Typical requirements vary by region and may include CE marking, IP ratings, and SIL readiness depending on installation. Always verify exact certification status with Eaton’s specification sheet (ETR-4000-2A2LB0) for your country and application.
Maintenance is streamlined by removable terminals and conformal-coated circuit boards, which reduce field downtime. The device’s robust protection features and remote communication enable predictive maintenance and faster fault resolution, contributing to a lower total cost of ownership and improved system uptime over traditional protection relays.
