Art-Nr.: USR3060
UR 3060 Unterspannungsmessrelais
Product information
With the application of the 3 phases L1-L2-L3 and the N conductor, the built-in relay (2 changeover contacts) must pick up and the green LEDs must light up. However, the prerequisite for this is that the voltage does not fall below the setpoint UN 0,85 (type UR 3060).
If the rated voltage fails or falls below, or if one or more of the 3 phases or the N conductor fails, the corresponding LED flashes and the relay returns to its rest position.
Monitoring in a 1-phase network is carried out with the connections L and N. The failure of one or more phases or the N conductor is indicated by a red, flashing LED. In fault-free operation, these LEDs are green.
