Packaging 10 3061 0,10Low voltage-measure relay with phase recognition 2 break contacts Low voltage measuring relay with rotary field recognition - 3-phase supervision for low voltage and phase failure - Neutral supervision - Width 17,8mm (1 unit) - Switching voltage 85%, delay 0,5 sec; - Accords to DIN EN 50172 (DIN VDE 108-100) - Power consumption less than 1W - LED indication for phase and neutral faults, phase and N-fault - Test key Principle of operation Low voltage monitoring for AC in 3-phase networks (each phase against N) with fixed adjusted switch level and fixed time delay.The relay is triggered off when the measured voltage of all connected phases exceeds the level of Us.The green LED lights up.As soon as the voltage of one of the connected phases sinks below the set value for longer than 0.5 seconds, the relay falls back to its starting position and the corresponding red LED will flash.If the voltage exceeds the level again for at least 0,5s,the relay switches back to normal operation.If the phase (left run) changes,the relay likewise falls back in the initial position.The LED for phase flashes. 1/18 1030610,10Low voltage-measure relay with phase recognition
