                        Is the LR9D5369 overload still available

                         Yes it is

                        What are the wiring terminals on the IEC LRD* overload relays?

                        Tesys D line Overload Relays
                         
                        Resolution:
                        The normally closed overload contact are terminals 95 & 96; and the normally open overload contact are terminals 97 & 98.
                        T1 T2 and T3 are the load terminals. 

                        The normally closed control circuit contact will open when there is a fault, this contact is typically used in series with the control circuit. 

                        The normally open trip signal contact closes when a fault occurs which is typically used to control a pilot light, or alarm.

                        Can I use a LA9D6569 reversing kit with LC1D40AU7 contactors

                        No, correct kit is a LAD9R3.

                        What is the reference for the separate mounting kit for LRD4369 overload relay

                        The LRD43xx type of thermal overload relays are directly mounted to the contactors LC1D115 & LC1D150 only. There is no separate mounting kit for the LRD43xx.

                        If a separate mounting is required for the contactors LC1D115 or LC1D150 type, then LRD336xx shall be selected as these range of overload relays have indepentdent mounting and have similar setting range and are of Class 10A.
