2.2.2.2 3RT2 power contactors
The table below shows the different versions of the 3RT2 power contactors. The contactors
are equipped with AC and DC drive options. An electronic UC drive can also be ordered for
size S0. Special communication-capable contactors are available for integration via
AS-Interface or IO-Link by means of 3RA27 function modules; these contactors enable the
voltage of the main circuit to be tapped directly. The communication-capable power
contactor is supplied with a 24 V DC drive option.
