                          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. 

                           

                          What is the overload to suit LE3D12N7 star delta starter?

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

                          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

                          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 is the part code for a DOL 1P 240V AC Coil 4kW 9A, with 10-12A overload

                          Use a PDL56DOL9LOBGY and a LRD16 overload.

                          What is the replacement for a Clipsal 6CTR38/15?

                          This is part of the old Clipsal 6 series contactors which are no longer available .It is an old Clipsal overload, which would need to be changed over to a Schneider LC1D range contactor with overload to suit . Over load to use is either LRD21 for 12-18A or LRD16 for 9-13A

                          For correct selection of contactor and overload required please call Schneider Electric on 1300 369 233

                          What is the difference between the LA7D305 and LAD7305, remote control reset mechanism by flexible cable?

                          Cause:
                          Choosing the correct part number

                          Resolution:
                          LAD7305 is for use on LRD01 to LRD35 , LR3D01 to LR3D35, and LRD313 to LRD365.
                          LA7D305 is for use on all other relays (except LRD01 to LRD35 and LR3D01 to LR3D35).

                           

                          What is the part number of an overload that has a setting of 0.57A?

                          LRD04 has a setting of 0.40A to 0.63A for use with contactors LC1D09 up to LC1D38.

                          What is the alternative for PDL56T9120 overload?

                          The alternative is LRD16 but this will not fit the contactor in the 56 series starter as it is for the LC1D range of contactors. The PDL56T9120 is no longer available.
                          The new range of 56 series starters, 56DOL, have LC1D contactors and LRD overloads (not fitted).

                          What is the difference between a LR3D21 and LRD21?

                          What is the interlock for LCD18

                           The part code is LAD9R1V

                          What is the alternative to the PDL56T992 Overload

                          the LRD12 is the same rated overload to suit the current range of 56 series DOL starters but will not fit on the old DOL starter the 56T992 was used for.                                                                                                                                                                                                                                      

                          What is the replacement overload similar to LR2D1301

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

                          What is the part number for a class 20 version of the LRD340

                           The part code LRD340L

                          Can the LRD01 to LRD35 range be put back to manual from automatic.

                          This LRD range cannot be put back to Manual reset, once the overlaod has been changed from Manual (factory default) to Automatic.

                          Identifying differences between two similar part numbers

                          Resolution:
                          Both will remotely stop (trip) or electrically reset the overload, however;
                          LAD703 is used on Tesys overload LRD01 through LRD35 and LR3D01 to LR3D35.
                          LA7D03 is used on all other LR*D overload relays other than LRD01 to LRD35 and LR3D01 to LR3D35.

                          Environment:
                          US Product

                          Cause:
                          The overload LR2D13 is not recognized in pricing system or on the cross reference website (https://quotefast.schneider-electric.com/xref/CrossReference.jsp)
                          It is therefore unclear what has replaced this overload.

                          Resolution:
                          LR2D13 is an incomplete part number from an obsolete overload relay.  The full part number is printed on the side of the unit, but only LR2D13 is printed on the front.

                          The following video demonstrates how to locate the full part number on the LR2D series overload relays:

                          What is the replacement for a LR2D1321?

                          The replacement is a LRD21. This will need to be either remotely mounted or the contactor will need to be replaced as it won't fit the existing contactor.

                          Is there a direct replacement for TR2D09307 overload?

                          There is no direct replacement for TR2D09307 but alternative is LRD07 ( will not fit to existing contactor)
