ABB REF542PLUS 76A3NFNN361SU36 is a compact digital bay control technology solution launched by ABB Group. It belongs to protection and control devices and is commonly used in various application scenarios of medium-voltage power systems, specifically as follows:
Integrated Functions: It integrates measurement, monitoring, protection, control, and self-diagnosis functions. It can real-time monitor key parameters of the power system such as current and voltage, continuously monitor equipment status, provide comprehensive protection against electrical faults like overloads and short circuits, support remote operation and monitoring, and self-diagnose potential issues to reduce downtime and maintenance costs.
Communication Capability: With integrated communication protocols, it can be easily integrated into ABB or third-party substation automation systems, enhancing system interoperability and efficiency.
Application Scenarios: Suitable for medium-voltage applications such as feeder protection, transformer protection, and motor protection. In power systems, it ensures rapid isolation of faulty areas during faults, improves system reliability, and guarantees the stable operation of substations and industrial power systems.
Design Features: It adopts a compact design with a robust structure, ensuring reliable performance even in harsh environments. Equipped with a high-definition display screen, the panel has configuration, monitoring, and operation functions, which can real-time display the status and parameters of the relay for easy viewing and operation by users. The parameters of the protection scheme can be changed through the human-machine interface control unit without the need for a personal computer.
Programming Support: It supports the use of the "Function Block" programming language (FUPLA), making it convenient for engineers, especially non-software experts, to update switchgear operations and processing
