                  Cause:
                  Product selection

                  Resolution:
                  No.  The voltage code BD3 is for the CA4D Low Consumption relays only.   A 24 volt DC coil with built in transient suppression is not available on the CA3D relay.    Use the add on LA4DA1E varister style or the LA4DC1U diode style add on transient suppressors on the CA3D relays.
                   

                  Is it possible to add side instantaneous auxiliary contacts blocks to the TeSys D DC coil contactors and relays?

                  No, with the TeSYS D range, the DC coil contactors (both standard and low consumption) only allow front mountable auxiliaries.
                  The part numbers LAD8N11, LAD8N20 and LAD8N02 will fit only the contactors with AC coils.
