Three-phase Four-wire Protection Relay: Includes overvoltage, undervoltage, phase failure, phase error, and imbalance protection. Overvoltage, undervoltage, protection delay, recovery delay, and imbalance values can be independently set. The relay disconnects the load during voltage faults and reconnects when normal conditions return. Designed for three-phase distribution lines, with a global voltage range and detailed fault indicators for troubleshooting.
