    CM-MPS .x1 Multifunctional Three-Phase Monitoring Relays

    The CM-MPS.x1 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.11 and CM-MPS.21 also monitor the neutral for interruption. The threshold values for over- and undervoltage and phase unbalance are adjustable.,CM-MPS.11 and CM-MPS.21 are 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 %).

    Monitoring of three-phase mains for phase sequence (can be switched off), phase failure, over- and undervoltage as well as phase unbalance
    Interrupted neutral monitoring possible with CM-MPS.11 and CM-MPS.21
    CM-MPS.11 and CM-MPS.21 can also be used to monitor single-phase mains
    Threshold values for phase unbalance, over- and undervoltage are adjustable as absolute values
    Tripping delay can be adjusted or switched off by means of a logarithmic scale
    ON-delayed or OFF-delayed tripping delay selectable
    Powered by the measuring circuit
    True RMS measuring principle
    2 c/o (SPDT) contacts
    3 LEDs for status indication
