Three-Phase Three-Wire Protection Relay: Offers overvoltage, undervoltage, phase loss, and phase sequence protection. When voltage faults (beyond set limits), phase loss, or phase sequence errors occur in a three-phase circuit, it automatically cuts off the load. It continuously monitors the voltage, and once the parameters return to normal, the load restarts. It is mainly used in three-phase power distribution circuits to protect downstream electrical equipment.
