Three-phase Three-wire and Four-wire Universal Protection Relay: Features overvoltage, undervoltage, phase failure, phase error, and imbalance protection. Overvoltage and undervoltage values, along with protection delay, can be set by the user. The relay disconnects the load during faults and reconnects when the line stabilizes. Suitable for protecting downstream equipment, with global voltage support and clear fault indicators.
