Feature

• CM-PSS Three-Phase Monitoring Relays. The CM-PSS.x1 are monitoring relays for three-phase mains. They monitor the phase parameters phase sequence, phase failure, over- and undervoltage. The threshold values for over- and undervoltage are fixed. Monitoring of three-phase mains for phase sequence (can be switched off), phase failure, over- and undervoltage Fixed threshold values for over and undervoltage 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
