                          hide show

                          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 overload can be used with an LC1D65AU7?

                          You can use the Everlink range which is LRD313 - LRD365

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

                          Issue:
                          Identifying differences between two similar part numbers.

                          Product Line:
                          IEC contactors and starters

                          Environment:
                          Products sold and used in the United States

                          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 difference between a LR3D21 and LRD21?

                          What is the Overload for LC1D50AU7 range is 37..50 Amps?

                          LRD350

                          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

                          What is the setting range for an LRD350

                           The setting range is  37 - 50A

                          What is the Din rail terminal block to suit the LRD12?

                          The LAD7B106 fits the LRD01 to LRD35 range.
                           

                          What is the replacement for the old thermal overload relay LR2D3359?

                          The part number is as follows: LRD365

                          What overload can be used for the LC1D32 contactor @16amps?

                          either the LRD21, 12 to 18 amps.
                          Or the LRD22, 16 to 24 amps.

                          Video: What is the replacement for an LR2D13?

                          Issue:
                          What is the replacement for an LR2D13 overload relay?

                          Product Line:
                          LR2D1301

                          LR2D1322

                          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:
