FAQs
The EBR-3000-2B0BA1 is designed for industrial feeders and bus protection in environments that require reliable fault detection. It operates from 40-250Vac or 19-300Vdc and supports a wide ambient temperature range (-20°C to 60°C). With projection-panel mounting and removable terminals, it simplifies installation and service in compact control cabinets and substation panels.
Integration is achieved via Modbus RTU and DNP3.0 RTU over RS485. This enables real-time data exchange, remote monitoring, and easier fault analysis. The device’s eight digital inputs and six digital outputs provide essential signaling for SCADA trends, alarms, and interlock logic, reducing commissioning time and improving outage response.
Yes. It supports both 40-250Vac and 19-300Vdc input ranges, allowing flexible deployment across panels powered by AC or DC sources. This compatibility reduces inventory requirements and simplifies upgrades in mixed-electrical environments.
The relay presents a burden of 10 W / 17 VA, which translates to a modest impact on auxiliary power budgets and thermal design. Coupled with its compact projection-panel form, the EBR-3000-2B0BA1 minimizes heat gain and fits into standard cabinet footprints, easing enclosure planning.
Key advantages include a projection-panel mounting method, removable terminals for quick wiring changes, and a robust 5 A contact rating for reliable switching. The combination supports faster commissioning, easier maintenance, and straightforward expansion or replacement in busy feeder protection schemes.
