With a wide supply range of 19-300 Vdc and 40-250 Vac, the EBR-3000 reduces the need for multiple protection devices and simplifies procurement. This flexibility lowers stocking costs and accelerates installation across mixed-voltage feeders. It is ideal for feeder protection in industrial plants, substations, and retrofit projects where voltage conditions can change. The unit provides eight digital inputs, six digital outputs, and a single current sensing input, enabling enhanced monitoring and remote control of feeder operations. This integration improves fault signaling, interlocking capabilities, and panel automation, delivering measurable reductions in commissioning time and maintenance overhead. Communication is built around Modbus RTU plus DNP3.0 RTU via RS485/DSUB, enabling seamless SCADA and energy-management system integration. Operators gain visibility and control without extensive custom wiring, which supports overall operational efficiency. The projection panel mounting and removable terminals simplify field wiring and service access, while conformal coating supports reliability in harsh environments. Operating across -20°C to 60°C with a burden of 10 W / 17 VA and a 5 A contact rating, the relay combines rugged performance with economical power budgeting for continuous operation. This mix of robust protection, installation flexibility, and diagnostics translates into lower lifecycle costs for OEMs, panel builders, and maintenance teams.
