ABB Stotz S&J Phase Sequence Relay CM-PFE: additional details
The three-phase monitoring relays of the CM series provide reliable and continuous monitoring of a three-phase network, ensuring the smooth 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.
