Overview
The ABB REF542PLUS 2RCA029395 is a compact, multifunctional feeder terminal designed for medium-voltage switchgear applications. It integrates protection, control, measurement, and communication in a single unit, reducing panel complexity and improving operational efficiency. The device supports IEC 61850, Modbus TCP, and Profibus DP protocols, making it compatible with modern SCADA and substation automation systems.
Its modular architecture allows flexible I/O configurations and hot-swappable modules, enabling quick adaptation to different feeder types. Moreover, the terminal features a graphical LCD interface for intuitive local control and diagnostics. With IP54 front protection and robust internal shielding, it performs reliably in harsh industrial environments. Therefore, it’s ideal for both new installations and retrofit upgrades in utility and industrial networks.
In addition, REF542PLUS supports advanced protection functions such as overcurrent, earth fault, and motor protection, ensuring fast fault detection and system stability.
