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

                              Issue:
                              Identifying differences between two similar part numbers.

                              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 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 you remotely reset electronic overloads LR9D?

                              No. You cannot remotely reset LR9D electronic overloads.
                              There is no provision or attachment  to wire external reset button to overload.

                              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 Din rail terminal block to suit the LRD12?

                              The LAD7B106 fits the LRD01 to LRD35 range.
                               

                              Do we have Type 2 Co-Ordination Chart for the LT47 overload relays?

                              LT47 is not an overload relay but an overcurrent relay, working on a definite time characteristic : current threshold and time based function.

                              We do not have Coordination type 2 tables for LT47.
                              However, LT47 is an overcurrent relay. It performs a motor current measurement through its internal CT. So, LT47 doesn't add impedance to the motor control circuit and the coordination only results from the characteristics of the short circuit protection (fuses or circuit-breaker) and of the contactor. So the coordination tables we publish for LTMR can be used when LT47 is used.

                              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
