[John Frake]

I have purchased 3 of these marked as follows:

A-665 then 115 NO 60
AC-684 then 115 NC 10
E-1207 then 120 N.O. 60
My guess is that the first number is some kind of serial number the second refers to the max ac voltage across the contacts the cold status of the contacts and the time in seconds for said status to change. Does anyone know if this is corrrect?

Thanks in anticipation of your help.
