Elektrisch schemalezen Aan-Uit, hoofd- en stuurstroom met een 3-fase motor en thermisch relais

Here I'll explain how the main and control circuits work together in a 3-phase motor circuit. I'll also cover the thermal pack/relay or protection system, explaining why it's needed. You can connect this circuit to the practical boxes and actually test it. NOTE! Test the control circuit first, then connect the main circuit. Work carefully with the different wire colors.
