                          What is the 415v remote reset for the LRD14 overload?

                          The part number for the415VAC or DC remote reset for the LRD01...35 and the LRD313....365 is LAD703N
                          See data sheet for more information......https://eshop.schneider-electric.com/product.aspx?org=21&lang=1&dist=276&prod_id=LAD703N...User-added image
                           

                          Alternative Overload for the PDL56T992 (6.0-9.2A)

                          Either go for the LRD12 (5.0-8.0A) or the LRD14 (7.0-10.0A) depending on the size of the motor. This will not fit the old 56 Series DOL starter

                          What is the overload to suit LE3D12N7 star delta starter?

                          Overload to suit LE3D12N7 will be either LRD12, LRD14 or LRD16 depending on application.

                          Is there a replacemnet for the old DOL motor starters like LE1D12U7R10?

                          All of the LE1D12U7R** parts have now been Divide into two parts enclosed starter and thermal overload see table for the new part numbers/ format:

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

                          Product Line:
                          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.
