YC9VA-3
YC9VA-3
The YC9VA-3 is a three-phase digital voltage protection relay designed to monitor and protect electrical systems against overvoltage, undervoltage, and phase abnormality conditions. It continuously supervises the three-phase supply and automatically disconnects the load when voltage exceeds preset safety thresholds or phase failure occurs.
The device is suitable for industrial panels, commercial distribution systems, motor protection, and equipment requiring stable three-phase power supply.
