Overview
The ABB REF 543 Protection Feeder Terminal is engineered to safeguard and control electrical feeders in medium-voltage applications. It integrates protection, measurement, control, and communication functions into a single compact unit. The terminal supports various network configurations, including isolated neutral and resonant-earthed systems, making it highly adaptable across industries.
Moreover, the REF 543 includes programmable logic control (PLC) features that enable automation sequences and interlocking schemes. Its modular design simplifies installation and maintenance, while its robust diagnostics improve fault detection and system reliability. In addition, the terminal supports remote access and SCADA integration, enhancing visibility and operational control.
For instance, in a mining substation, the REF 543 can detect phase faults and initiate breaker trips within milliseconds, preventing equipment damage and ensuring personnel safety.
