This minimum current value is a function of the relay auxiliaryvoltage range (Ua).Remarks:– The presence of auxiliary relays, such an anti-pumping systemfor instance, in the trip circuit must be taken into account for the R1resistance values specification.– It is assumed the maximum variations of the auxiliary voltagevalue are ±20%.OrderingCodeTHVWRelay auxiliary power supplyNominalvoltage rangeVx48 – 250 Vdc48 – 240 VacSpecial EA (**)48 – 250 Vdc48 – 240 Vac48 – 250 Vdc48 – 240 Vac48 – 250 Vdc48 – 240 VacOperatingvoltage range38.4 – 300 Vdc38.4 – 264 VacNominalVoltage range24 – 250 Vdc24 – 240 VacMinimalpolarisationvoltageLogic InputsMaximumpolarisationcurrentHoldingcurrentafter 2 ms19,2 Vdc19,2 Vac 35 mA 2.3 mAMaximumcontinuouswithstand300 Vdc264 Vac38.4 – 300 Vdc38.4 – 264 Vac 129 Vdc 105 Vdc 3.0 mA @ 129 Vdc 145 Vdc38.4 – 300 Vdc38.4 – 264 Vac 110 Vdc 77 Vdc 7.3 mA @ 110 Vdc 132 Vdc38.4 – 300 Vdc38.4 – 264 Vac 220 Vdc 154 Vdc 3.4 mA @ 220 Vdc 262 Vdc(**) Logic input recognition time for EA approval.
