Do TeSys U range of starters come with built in free wheeling diodes or varistors for dc coils?

There is no built in  Suppressor with diodes or varistor embedded in TeSys U.
The Tesys U principle is fully different with a standard Electro-mechanical contactor with standard coil.
The energy to operate the coil is generated by an electronic converter, then we have a full separation between the coil and the control circuit.
So there is no need for a built in Diode or Suppressor.
