Current control ➜ EI AC/DC current control ■ Space savings, accurate measurement and optimized functions all improve the efficiency of your electrical installation. ■ Control : Select ’’Over-current’’ or ’’Under-current’’ control mode, by means of a dip switch on the underside of the unit. ■ Safety : Choose whether or not to activate the fault memorisation function, and set the threshold crossing delay T1 and the inhibit time delay T2 in the same way. In addition, AC/DC mode is detected automatically. ■ Accuracy : 3 products, EIL, EIH or EIT enable you to choose the best product for greater accuracy of measurement, provided by a microcontroller.
