Three-phase Four-wire Protection Relay: Equipped with overvoltage, undervoltage, phase failure, phase error, and imbalance protection. Overvoltage, undervoltage, and imbalance values can be independently configured by the user. The relay disconnects the load during voltage faults and reconnects when normal conditions are restored. Suitable for protecting downstream devices in three-phase distribution systems, with a full voltage range and fault indicators for easy troubleshooting.
