We do not have dc motor starters in our offer
However For the DC network, you have to select the contactor as per the DC selection chart & then you can select the overload relay as per the current rating.
Please refer the attached contactor selection chart in DC & then you can select the contactor reference as per your specification, the current rating is given for various DC voltage ratings. For ex for 110V DC, up to 20A application you can select the LC1D09** contactor with 2 poles in series. & you can select the LRD O/L relay as per required rating
Please find the attached document showing all the details regarding the maximum current rating which can be used of GV2 & GV3 MPCB in DC application as per the different operation voltage. Also you can find out the breaking capacity value of these MPCB in DC voltage in this document.
