REF542PLUS 1VCF75200 | Feeder Protection Terminal

ABB REF542PLUS 1VCF75200 Technical Specifications

Main Features and Advantages

The ABB REF542PLUS 1VCF75200 delivers comprehensive protection and control for electrical distribution feeders in demanding industrial environments. Combining multilevel overcurrent protection with earth fault detection, this terminal provides selective tripping coordination through advanced time-current characteristics (TCC) curves. Its integrated motor protection includes stall prevention, underload monitoring, and start supervision, significantly reducing failure risks in critical processes.

REF542PLUS-1VCR007346

Communication flexibility stands out with native support for IEC 61850 Ed.2, enabling seamless integration into modern substation automation systems alongside traditional protocols like Modbus RTU and Profibus DP. The large graphical display provides real-time metering data including power quality parameters such as THD and voltage unbalance. Cybersecurity features include role-based access control, event logging with digital signatures, and secure parameter setting via DIGSI software. The compact design achieves high functionality density while maintaining front-panel accessibility for operation without cabinet door opening.

Application Areas

The REF542PLUS 1VCF75200 excels in critical feeder protection across multiple industries. Manufacturing facilities deploy it for motor control center (MCC) feeder protection in production lines. Industrial plants utilize it for critical pump and fan motors in petrochemical processes requiring specialized start and stall protection. Power distribution applications include transformer incomer protection and bus-tie feeder control in MV switchgear systems.

Infrastructure implementations feature in airport electrical distribution networks where selective tripping prevents cascading failures. Marine and offshore installations leverage its DNV GL certification for platform power management systems. Renewable energy applications include wind farm collector substations and solar plant inverter feeders. Its extended temperature tolerance supports desert mining operations and arctic oil field electrical networks requiring reliable protection in extreme conditions.

Installation and Maintenance

Installation requirements: Mount the ABB REF542PLUS 1VCF75200 vertically on DIN rail according to torque specifications. Ensure adequate clearance for wiring access and heat dissipation. Use shielded twisted-pair cables for communication ports grounded at one end only. Verify CT ratios and burden capacity before energization.

Maintenance recommendations: Perform annual testing of protection functions using primary injection test sets. Verify time-current coordination curves during system expansions. Update firmware during planned outages using PCM600 software. Maintain parameter backups offline and periodically check self-diagnostic logs for early component failure indications.
