Description
Product Description
The ABB REF542PLUS 1VCF752000 is a comprehensive feeder terminal unit (FTU) and multi-functional protection relay designed for primary distribution substations and industrial power systems. This device integrates protection, control, measurement, and communication functions into a single, compact unit, making it a cornerstone of modern smart grid and industrial switchgear. The REF542PLUS is engineered to protect and control medium voltage circuits, motors, transformers, and capacitor banks. The specific model 1VCF752000 denotes a standard configuration with a defined set of protection functions, I/O capabilities, and communication ports. By combining multiple traditional discrete devices (relays, meters, RTUs) into one intelligent unit, the ABB REF542PLUS simplifies panel design, reduces wiring, and provides extensive data for condition monitoring and energy management. Its robust construction ensures reliable operation in electrically harsh substation environments.

Comparisons with Competing Products
The ABB REF542PLUS competes with other multifunction feeder protection relays such as the Siemens SIPROTEC 7SJ8x, the Schneider Electric MiCOM P3xx, and the GE Multilin F650.
-
Vs. Discrete Relay Solutions: Compared to using separate overcurrent, earth fault, and meter relays, the REF542PLUS offers vastly superior integration, data richness, and cost-effectiveness over the total system lifecycle.
-
Vs. Other Multifunction Relays: Its key strengths lie in ABB’s strong utility heritage, the depth of its application-specific configuration packages (e.g., for motor or transformer protection), and its robust mechanical design. The specific feature set, communication options (like IEC 61850 implementation), and usability of the configuration software are typical differentiators.
-
Vs. Basic PLC-based Control: While PLCs can perform control logic, the ABB REF542PLUS 1VCF752000 is purpose-built for protection with certified tripping times, rigorous hardware design for high fault currents, and pre-validated protection algorithms, making it the unequivocal choice for safety-critical electrical protection.
Selection Suggestions and Precautions
-
Detailed Function Specification: Precisely define all required protection functions (e.g., directional overcurrent, voltage restraint), measurement needs, and the number of required binary I/O points to ensure the REF542PLUS model selected covers them.
-
Communication Protocol Strategy: Determine the required station communication protocol (IEC 61850, Modbus, PROFIBUS) at the start of the project. The 1VCF752000 variant must be ordered with the correct communication module.
-
Auxiliary Voltage Match: Confirm the device’s power supply rating matches the available DC or AC control voltage in the switchgear cell to avoid damage.
-
Professional Configuration and Testing: Configuration requires specialized PS501 software and expertise. All protection settings must be calculated by a qualified protection engineer. Prior to commissioning, primary injection testing and functional tests are mandatory to validate the ABB REF542PLUS‘s operation.
-
Cybersecurity: When connected to Ethernet networks, implement appropriate cybersecurity measures (firewalls, network segmentation) as outlined in the device manual and relevant standards to protect the critical protection and control system from unauthorized access.
