Monitoring relay 400 V AC (max) 2 change-overs Metz Connect 110292032230 1 pc(s)
This monitoring relay for monitoring the correct phase sequence L1-L2-L3 (clockwise rotation) and monitoring of the individual phase voltages on total failure. The phase voltages to be monitored are connected to terminals L1-L2-L3, terminals 11, 14 or 21, 24 of the relay output contacts are connected upstream of the excitation coil of the motor contactor. The output relay switches on when the phase sequence is correct (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 is not required for the monitoring relay. The device is to be connected with N. When the neutral wire fails, the output relay returns to its rest position (green LED off).This text is machine translated.
