7 Electronic motor starter EMS-…-SWD-ADP7.3 ProjectionSmartWire-DT modules IP20 09/17 MN05006001Z EN www.eaton.com 1597.3.5 Tripping characteristicThe electronic motor starter features two different trip characteristics(class10, class 10A) for protecting motors against thermal overloads. Thecharacteristic curve used will depend on the device model's current range(2.4 A or 9 A), and, in the case of devices with 9 A, on the value set for themotor current. The following table shows when each trip characteristicapplies:Table 37: Applicable trip characteristic classesWhen the class 10A trip characteristic is used, the electronic motor starterwill trip within 2 seconds if the load current exceeds 45 A.Figure 59: Tripping characteristics Class 10Figure 60: Tripping characteristics Class 10ADevice Type Motor current[A] set valuetripping character-isticsEMS-...-2.4-... 0.18 – 2.4 Class 10EMS-...-9-... 1.5 – 4 Class 10EMS-...-9-... 4.5 – 9 Class 10At [s]1 2 3 4 5 6 7 8 9 10 I / In110100100060 4030 20600 400300 2006 43 20.6 0.40.3 0.20Class 101 2 3 4 5 6 7 8 9 10 I / In110100100060 4030 20600 400300 2006 43 20.6 0.40.3 0.20Class 10 At [s]
