The CM-PVS.41S three-phase monitoring relay provides precise protection for motors, pumps, and industrial equipment operating on three-phase power. Designed for reliable voltage supervision, it detects phase loss, overvoltage, and undervoltage conditions while allowing customized threshold and delay settings. Its adjustable tripping delay (0–30 s) prevents nuisance tripping during transient conditions, ensuring system stability. The relay includes dual SPDT contacts for control flexibility and offers a sealable transparent cover for configuration security.
