      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
