Three-phase Four-wire Protection Relay: Features overvoltage, undervoltage, phase failure, phase error, and imbalance protection. Overvoltage and undervoltage settings, along with action recovery delay, can be set independently by the user. When faults occur, the relay disconnects the load and monitors the voltage, reconnecting when the parameters normalize. Ideal for protecting downstream electrical equipment, with universal voltage support and detailed fault indicators.
