Each Siemens 3RT1 contactor comes with a specific coil voltage and voltage code that will match the control voltage of your application. This is not to be confused with the line voltage, which usually is 480v and only applies to the voltage of you 3 power poles. The coil voltage, or control voltage, is what actuates or enables your coil to operate the 3RT contactor.
To find this coil voltage, you will need to look on the top of the contactor behind the three screws that you see on the front of the contactor (click here for a picture of where to find the coil voltage). Now in between two screws is a plastic piece which is your coil and will have the coil voltage listed (examples are 24v 50/60Hz, 110v50Hz/120v60Hz, etc). Once you have this voltage, you can select the appropriate contactor.
