Overview
The ABB REF542PLUS 1VCR007346 is a multifunctional digital feeder terminal used in medium-voltage distribution systems, particularly within smart switchgear. It combines protection, control, measurement, and supervision into a single unit, streamlining substation automation and reducing panel complexity.
This terminal is part of ABB’s Relion® series, optimized for air-insulated switchgear (AIS) and gas-insulated switchgear (GIS). It supports IEC 61850, Modbus, and DNP3 protocols, enabling seamless integration into modern SCADA and substation automation systems.
Moreover, REF542PLUS offers flexible configuration, hot-swappable modules, and HMI interface options, making it ideal for both new installations and retrofit projects. Its compact footprint and rugged design ensure reliable operation in harsh environments, including high humidity, dust, and temperature extremes.
