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

                    Identifying auxiliary contact blocks for Tesys D contactors

                    Product Line:
                    IEC contactors and starters

                    Products sold and used in the United States

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

                    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.

                    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
