The three-phase monitoring relay is designed to monitor various phase parameters including phase failure, phase sequence over/undervoltage, and phase unbalance. It has a measuring range of 342 to 418 VAC (L-L) and operates with a rated control supply voltage of 380 VAC. The relay is equipped with 2 CO (SPDT) outputs and features an adjustable tripping delay ranging from instantaneous to 30 s (0, 0.1-30 s). Additionally, it is designed with double-chamber cage connection terminals for easy installation.
