Product Code: CM-PVS.81S

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 200 to 400 V AC (L-L) and operates with a rated control supply voltage within the same range. This relay features 2 CO (SPDT) outputs and allows for adjustable tripping delay from instantaneous to 30 seconds (0, 0.1-30 s). Additionally, it is equipped with double-chamber cage connection terminals.
