ABB 487V1401-6000 Distribution Protection System

ABB 487V1401-6000 Distribution Protection System is a DPU2000-series protection and control unit designed to protect medium-voltage feeders in substations and distribution networks. As part of ABB’s Distribution Protection Unit family, it aligns with models such as DPU2000, DPU1500R and DPU2000R, delivering protective tripping, control logic, and interoperability with ABB protection architectures. The device supports Modbus and Modbus Plus communications for integration with supervisory systems and remote monitoring, enabling seamless data exchange with plant controllers and SCADA. Its protection function library covers fundamental schemes such as overcurrent and earth fault protections, directional protection options, and coordinated reclosing, allowing fast, selective isolation while preserving continuity on adjacent feeders. ABB’s technical guides, including the DPU2000/1500R/2000R Modbus automation guide, describe how DPUs operate within a comprehensive protection, control and communication framework. Typical applications include MV feeder protection and sectionalizing in distribution substations, where the 487V1401‑6000 can be integrated into ABB’s broader protection, distribution & control portfolio to enhance reliability and visibility of the power distribution network.
