The three-phase monitoring relay is designed to monitor all phase parameters, including over/undervoltage, phase unbalance, and phase failure. It has a measuring range of 350 to 580 VAC (L-L) and operates with a rated control supply voltage within the same range. The relay features 2 CO (SPDT) outputs with contacts rated at 250 V/4 A. It offers the option for phase sequence monitoring and automatic correction, as well as an adjustable ON or OFF tripping delay. The relay is equipped with double-chamber cage connection terminals for secure connections.
