                          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 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

                          Will the LR3D325 overload relay fit a LC1D65G7 contactor?

                          Issue:
                          Will the LC1D65G7 mount to the LR3D325 overload relay?

                          Product Line:
                          IEC contactors and starters

                          Environment:
                          Products sold and used in the United States

                          Cause:
                          Identifying product compatibility

                          Resolution:
                          No, the LR3D325 is a overload relay with Everlink termination and will direct mount only to the LC1D40A to LC1D65A contactors.

                          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 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 overload to suit LC1D95U7 need to be 80-104A

                           Part code for the overload LRD3365

                          What is the overload for the LR2D Everlink range 23-32 Amps?

                          The correct code is LRD332.

                          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.
