Only reliable and continuous monitoring of a three-phase network guarantees the trouble-free and economic operation of machines and installations. Thus, the three-phase monitors of the CM range, according to the individual requirements, monitor the phase voltages, phase sequence, phase unbalance and phass loss.
CM-MPS is a multifunctional monitoring relay for three-phase mains. It is available with or without neutral monitoring and provides monitoring of all phase parameters: Phase sequence, phase loss, over- and undervoltage and phase unbalance.
The CM range also includes five more three-phase monitors with a lower function range. With their more specialized functionality, they are particularly suitable for most economic and cost-efficient three-phase monitoring.
