Hello Jim,
I do not think it is wise to use any component between phase and ground having a CM voltage limiting function. No component fits the requirements of EN 60950 RELIABLE for sufficient amount of time. I want re refer here to the requirements for solid state switches in EN 60730 which are severe, and just for differential mode. Especially MOV resistors tend to short circuit after a number of limiting actions, after a period of increasing leakage current. Regards, Ing.

The component will bridge basic insulation in a primary circuit. Thanks Judd Stewart Litton Data Systems 619.623.6639
