Art-Nr.: UER3068
UR 3068 Unter-/Überspannungsmessrelais
Product information
With the establishment of the connection to the supply voltage, the relay picks up in the fault-free case and the green LED lights up. If the monitored rated voltage is exceeded or fallen below, the relay returns to its rest position. The switching hysteresis is fixed at 2 %.
The device also includes one red LED each for monitoring the upper and lower set percentage value. In the event of a fault, these LEDs flash red.
