PFD2-E12, 400 V AC

The monitoring relay monitors the correct phase sequence L1-L2-L3 (direction of rotation to the right) and complete failures of individual phase voltages. The phase voltages to be monitored are connected to the terminals L1-L2-L3; the terminals 11, 14 or 21, 24 of the relay output contacts are connected ahead of the field coil of the motor relay.If the phase sequence is correct, the output relay is activated (green LED is on). In case of total failure of a phase, the output relay returns to its neutral position (green LED is off).A special supply voltage is not required for the monitoring relay. Only connect the device to N if the three phases to be monitored are connected to N over an electric circuit (e.g. temperature monitoring or similar).
