                          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 Din rail terminal block to suit the LRD12?

                          The LAD7B106 fits the LRD01 to LRD35 range.
                           

                          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).

                           

                          Is there a LE1M35N705 alternative or can coil be swapped out

                           The part codes you need is LE1D12N7 + LRD06

                          What is the alternative for the PDL Thermal Overload 56T9092 ?

                           The alternative is LRD05 (Note - these are not direct replacements)

                          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.


                           

                          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.

                          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)

                          LRD07

                          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 interlock for LCD18

                           The part code is LAD9R1V

                          What is the replacement overload similar to LR2D1301

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

                          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
