Product Details
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
