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

                          LRD350

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

                          Issue:
                          Identifying differences between two similar part numbers.

                          Product Line:

                          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 part number for a non everlink overload with same rating as the LRD350?

                          Part number for a non everlink overload similar current rating is the LRD3357, see data sheets on both

                          https://eshop.schneider-electric.com/product.aspx?org=21&lang=1&dist=276&prod_id=lrd350

                          What overload can be used with an LC1D65AU7?

                          You can use the Everlink range which is LRD313 - LRD365

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

                          The LAD7B106 fits the LRD01 to LRD35 range.
                           

                          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.

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

                          The part number is as follows: LRD365

                          What is the difference between LAD703 and LA7D03

                          Issue:
                          Identifying differences between two similar part numbers

                          Product Line:
                          IEC contactors and starters

                          Environment:
                          Products sold and used in the United States

                          Cause:
                          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.


                           

                          What is the alternative for the PDL 56T9062

                           The alternative is LRD05. Note - these are not direct replacements and can not be used on the old DOL contactors.
