On the Tesys D 3 Pole AC Contactor you will find the coil voltage marked at the top, behind the Power terminals of the Contactor, for example U7, 240V 50/60 Hz
For the DC Version, the coil voltage is marked on the front of the Contactor. Hence it has got complete part number for the Contactor on the front, for example: LC1D25BD for 24V DC Coil.
