Art-Nr.: USR3066
UR 3066 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 light up. 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 single-phase network is carried out with the connections L and N.
The type UR 3066 corresponds in its function to the type UR 3060, but is additionally equipped with a phase sequence display [LED green = right phase sequence, LED yellow = left phase sequence]. Additionally, there is a rotary switch for the undervoltage setting range and a rotary switch for setting the pickup delay time. 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.
