ABB REX010 Earth Fault Protection Unit for Generator Safety Systems

Description

TheABB REX010is anEarth Fault Protection Unitdesigned todetect and isolate ground faultsin electrical systems, preventing equipment damage and ensuring operational safety. It is widely used acrossdistribution networks, substations, industrial electrical systems, and renewable energy platforms. The REX010 supports bothAC and DC control voltages, providing versatility for different system architectures. It featuresfast response times (<30 ms)andModbus RTU communicationfor real-time fault reporting and remote diagnostics. This makes it ideal for applications requiringselective, high-speed earth fault protection. For example, in asolar power station, the REX010 can detect insulation breakdowns and initiate protective actions before equipment damage occurs.
