    I need to replace my C25DNF340 contactor on my compressor. It some times
    hangs open when I am working the compressor hard. How do I determine
    the coil voltage of the contactor?

    220V compressor should have a 220V coil Clay as you don't have a neutral to make 110V there. It should be listed maybe on the side or where the two wires at the top towards the back connect in your picture.

    Turn it on and measure it.

    If you look at the end of the contactor above the L1,L2,L3 connections you will see the coil and the voltage will be printed on it.
