Hi, I have a three-phase motor with a 380v contactor and coil and the motor guard, the question is how the 380v coil is fed with two live? since the 220v coil is a live and neutral, thanks

What I don't understand is the title "contactor and earth", what relation does the earth have for you in this?

Hi. Is the coil 220 or 380V? First you say one and then another tension. If it is 380 it is fed with two phases and if it is 220 with one phase and the neutral. Clarifies Regards

Hi. if between phase and neutral you have 220V between phases you will have 380 for a 380V coil you feed it with two phases, that is, it requires that you have three-phase and take two phases of three for the control circuit you should keep in mind that these types of contactors are only used when they are actuated through an interlock (another contactor). Not suitable for manual drives where standards require safety voltage regards
