    Hi Ansar,

    Can you provide more information on the relays. I can't identify them from the numbers that you gave. Perhaps you can link us to their descriptions or data sheets.

    Thank you for the clarification of your question. I personally do not know the answer but when I get some time I will do some research. Is it possible that we are comparing two different applications and one is for ground fault protection and the other is just using a residual ground current for sensing?
