Three-Phase Three-Wire Protection Relay with Voltage Unbalance Protection: Provides overvoltage, undervoltage, phase loss, and phase sequence protection, as well as voltage unbalance protection. Overvoltage, undervoltage setpoints, and action delay times can be independently set by the user. When faults occur in the three-phase circuit, the relay automatically cuts off the load. It continuously monitors the voltage, and once the parameters return to normal, it closes the circuit to restart the load. Suitable for global applications with a wide voltage range and detailed fault indicators for easier troubleshooting.
