• CM-MPN Multifunctional Three-Phase Monitoring Relays. The CM-MPN.x2 are multifunctional monitoring relays for three-phase mains. They monitor the phase,parameters phase sequence, phase failure, over and undervoltage and phase unbalance.The threshold,values for over- and undervoltage and phase unbalance are adjustable. Monitoring of three-phase mains for phase sequence (can be switched off), phase failure, over- and undervoltage as well as phase unbalance Automatic phase sequence correction configurable 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 1x2 or 2x1 c/o (SPDT) contact configurable 3 LEDs for status indication
