产品介绍
The ABB UNS 3020A-Z, V3 (HIEE205010R0003) Ground Fault Relay is a dedicated protection device designed to detect and evaluate ground fault conditions in industrial power systems. It plays a critical role in safeguarding electrical equipment by identifying abnormal earth fault currents and initiating protective actions through associated control and tripping circuits.
This relay is engineered for use in complex power distribution and drive-related installations where reliable ground fault detection is essential for system safety and operational continuity. By continuously monitoring relevant electrical parameters, the UNS 3020A-Z, V3 enables early fault recognition, helping to prevent equipment damage and reduce the risk / secondary failures.
Built to meet industrial reliability standards, the relay features a robust hardware structure and stable signal processing behavior. Its design allows seamless integration into ABB protection and control architectures, making it suitable for both new system deployments and modernization projects.
