I do not know if I can answer that, simply because the words 3 Phase Power. Using this flow switch you will have to develop a by pass or what is called a delay circuit, this delay circuit will allow a period of time to pass before it look at the position of the flow switch. This is how you use this in a motor or pump control circuit, you would hook this to the coil circuit and interrupt the coil power if the pump is not deliveing flow.
