WEG CWB9 to CWB38 Coil Voltage Location
The above photo shows the location of the coil voltage for any WEG CWB9 through CWB38 3 pole IEC rated contactor. To find the coil voltage, as you are facing the front of the contactor, look at the top of the contactor, behind the three line side wires, between terminals A1 and A2. The coil voltage should be printed on the coil itself, and read something like 24v60Hz or 110v50Hz/120v60Hz.
