                    Can the single pole LA1DN and LADN auxiliary contact module be mounted on the TeSys contactors?

                    In which contactors can the LA1DN and LADN auxiliary contacts be mounted?

                    PRODUCT LINE
                    Auxiliary contacts for the Tesys D line

                    Tesys D-Line and Tesys F

                    These contacts will only fit on the following contactors:
                    Front mount only for LC1D40 through LC1D115 devices and LC1D40A - LC1D65A.
                    Left side mount only to LC1F contactors

                    What is the replacement for LA1EN11?

                    LA1KN11  is the replacement code.

                    NOTE: new commercial reference found might not be an exact match

                    What is the rated Short-Circuit Making Capacity (Icm) value for Compact NS MCCB?

                    The rated Short-Circuit Making Capacity (Icm) for Compact NS Moulded Case Circuit Breaker is as per the table attached and is dependent on the Short-Circuit Breaking Capacity (Icu).

                    (Note: Table is extracted from IEC 60947-2 document)

                    For NS 100 N, 100A MCCB at 440V, Short-Circuit Breaking Capacity (Icu) = 35 KA then, Icm = 2.1 x Icu = 73.5 KA. 
                    According to the IEC 60947-2, if the Rated Making capacity (Icm) is equal to the value specified in the IEC paragraph, it is not imperative to have a marking on the circuit breaker.
                    This is the reason for not publishing this information concerning the marking on the circuit breaker and the values in catalogue.
                    Icm can be calculated by the instruction as per the table provided in the IEC document.
