                              What is the replacement overload similar to LR2D1301

                              LR2D1301 discontinued 30/11/2003. Use a LRD01.

                              What is the replacement for LR2D1306 overload?

                              There is no direct replacement for LR2D1306 overload, the alternative is LRD06, which will not fit existing contactor.

                              LRD06 picture- Schneider-electric
                              For more information see:

                              What code is a mechanical interlock for the 4pole LC1D1150046 contactor?

                              LA9D11502 will fit the 4p LC1D115 and LC1D150 contactors

                              What is the part number for the replacement overload for the LR2D1308?

                              The part number for the replacement overload for the LR2D1308 is - LRD08

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

                              Tesys D line Overload Relays
                              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.
