The three-phase monitoring relays of the CM series ensure reliable and continuous monitoring of a three-phase network, guaranteeing the trouble-free and economical operation of machines and systems. Therefore, the three-phase monitoring relays of the CM series monitor the phase voltages, phase sequence, phase asymmetry, the presence of all phases, and the neutral conductor as needed.
