Overview
The ABB REX010 is an Earth Fault Protection Unit designed to detect and isolate ground faults in electrical systems, preventing equipment damage and ensuring operational safety. It is widely used across distribution networks, substations, industrial electrical systems, and renewable energy platforms.
The REX010 supports both AC and DC control voltages, providing versatility for different system architectures. It features fast response times (<30 ms) and Modbus RTU communication for real-time fault reporting and remote diagnostics. This makes it ideal for applications requiring selective, high-speed earth fault protection.
For example, in a solar power station, the REX010 can detect insulation breakdowns and initiate protective actions before equipment damage occurs.
