...phases 380VAC 50Hz motor (10A each phase maximum current) I think is it possible to use same components except for the three phases version where I have to use a lower current sensor (12.5A or 15A for example) In the attached schematic I used hall current monitor like ACS711 for 25A of maximum current. I used TRIAC T3035 (30A maximum current). Important is the detection of over current in shor circuit condition. In this condition I use OCF line of current monitor to disable gate of TRIAC and save it. In the attached schematic is not present microcontroller because is not an important component in simulation. I need to calculate power dissipation of triac in the maximum current and to have the correct size of customized heatsink made with simply aluminum to dissipate the necessar...
