●CM-MPS x3 Multifunctional Three-Phase Monitoring Relays

●The CM-MPSx3 are multifunctional monitoring relays for three-phase mains. They monitor the phase parameters phase sequence, phase failure, over- and undervoltage and phase unbalance. CM-MPS.23 also monitors the neutral for interruption. The threshold values for over and undervoltage and phase unbalance are adjustable. CM-MPS.23 is also suitable for monitoring single-phase mains. For this, all three external conductors (L1, L2, L3) have to be jumpered and connected as one single conductor. Phase sequence monitoring has to be deactivated and the threshold value for phase unbalance has to be set to the maximum (25 %).
