The monitoring relay is used to monitor the correct phase sequence L1-L2-L3 (clockwise direction) and to monitor the individual phase voltages for total failure. The phase voltages to be monitored are connected to terminals L1-L2-L3. The terminals 11, 14 or 21, 24 of the relay output contacts are connected in front of the excitation coil of the motor contactor. With the correct phase sequence, the output relay switches on (green LED on). In the event of total failure of one phase, the output relay returns to its rest position (green LED off). A special supply voltage for the monitoring relay is not required. The device should only be connected to N if the three phases to be monitored are connected to N via a circuit (e.g., temperature monitoring, etc.). EAN: 4250184118176.
