withou knowing your concrete application I would propose to use

the EMC supresssion modules 3RT19 16-1P..., 3-phase, <=5,5 kW

You find them in the Siemens low-voltage controls and distribution catalog LV1 -2008 page 3/98 and 3/109

But I do not know, wether this is exactly that what you need.
Please note: the modules are to use only up to 5,5 kW
regards

Hello,

the 3RT1916-1PA2 could be used for 5,6 kW motor, but caused by the current of 13,9 A

you have to use the contactor 3RT1025-1AF04 (size S0), but this is not compatible (mechanically) to the EMC module (size S00).

So we unfortunately are not able to offer a solution.
