UR 3067 Unter-/Überspannungsmessrelais
Product information
With the making of the connections to the three phases and the neutral conductor, the relay picks up in the fault-free case and the LEDs light up. The prerequisite for this, however, is that the RMS value of the monitored voltage moves within the set window voltage, i.e. this is not greater than Uso and not smaller than Usu.
The device also includes a phase sequence display [LED green = right rotating field, LED yellow = left rotating field]. In the fault-free state, all LEDs light up green. Fault messages are indicated by means of a red flashing LED. [L1-L2-L3-N]
