Some RCDs derive a power supply for internal electronics from the LN voltage. Not all of these are suited to a pole to pole voltage of 110 and may not operate, though I suspect most will.
Given the very short on-line data for the CPR25, the easiest is an Email or phone call to Contactum UK in the morning - they should know. If they do not, do not use them.
