                    Do we have replacement on Siemans part number 3TB4217OBB4?

                    The replacement part number for Siemens part 3TB4217OBB4 will be contactor part LC1D25BD and then the overload part number LADN22. 

                    So the customer needs to buy LC1D25BD + LADN22 to match 3TB4217OBB4.

                    What are the part codes for the red safety covers for TeSys D and U?

                    ETSNZ - Can Tesys F range contactors be used in safety applications?

                    According to IEC60947-4-1 appendix F, mirror contact is one of the means necessary to ensure safety for contactors
                    (in the standard "...mirror contact should not be relied upon exclusively as a means to ensure safety..." ).

                    TeSys F contactors do not include internal mirror contacts. So we, Schneider, do not actively promote TeSys F as a contactor for safety applications.
                    However, TeSys F can be fitted with auxiliary contacts add-on blocks. For some of these blocks LADN01, LADN02, LADN04, LADN11, LADN22, LADN31 and LADN13, a NC auxiliary contact has been recognised by VDE as mirror contact. This allows to use TeSys F in safety applications.
                    Attached are the VDE Certificates recognising the NC auxiliary contact with the blocks mentioned above as mirror contact.

                    To sum up and give clear answers to TeSys F and safety applications ;
                    1. If Tesys F contactor can be used for safety applications?

                    Yes, it can be used if, this is mandatory, it is fitted with one the above mentioned add-on blocks. VDE Certificate recognising the auxiliary contact as mirror can be provided.


                    2. When asked, can we answer that Tesys F have mirror contact, provided by auxiliary contact blocks?

                    Yes for the above mentioned add-on blocks and with the VDE Certificate

                    Are the auxiliary contacts on the D line contactors overlapping?

                    Issue:
                    Are the auxiliary contacts on the D line contactors overlapping?
                    Product Line:
                    Tesys D contactors
                    Environment:
                    IEC Contactors
                    Cause:
                    Product Characteristics
                    Resolution:
                    Except for the LADC22, they are non overlapping (break before make). Thus, the normally closed contact opens before the normally open contact closes. The LADC22 has 1NO and 1NC overlapping contact (make before break).

                    Will a single circuit auxiliary contact block, like a LADN10 or LADN01, fit onto the Tesys D09-D38 amp contactors?

                    Issue:
                    Identifying auxiliary contact blocks for Tesys D contactors

                    Cause:
                    single auxiliary contact block needed for use on a Tesys D line contactor

                    Resolution:
                    No, the single pole contact block will not fit . A LADN11,LADN20, LADN02 etc will fit. Anything with 2 auxiliary contacts in one block will fit.
