                          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 the LR2D Everlink range 23-32 Amps?

                          The correct code is LRD332.

                          What overload can be used with an LC1D65AU7?

                          You can use the Everlink range which is LRD313 - LRD365

                          What is the overload for LC1D65AU7 Contactor, when rating is 20-25A ?

                          17-25 Amps = LRD325
                          23-32 Amps =LRD332

                          What is difference between LC1D50U7 and LC1D50AU7?

                          Following are the differences between the LC1D50U7 and the LC1D50AU7:

                          LC1D50AU7 has everlink terminals.
                          LC1D50AU7....is slightly larger case and accommodate LRD3XX overloads
                          Whereas
                          LC1D50U7 contactors accommodate LRD33XX overloads.

                           

                          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

                          How to use LRD01…35 LRD33•• & LRD43•• and LRD33** as an indepentent relay?

                          The LRD relays has a solid tag to be used with LC1D** contactors. If you are not using LC1D contactors then using the following accessories you can terminate cable directly.

                          For LRD01…35 use the following part: LAD7B106
                          For LRD33•• & LRD43•• (3) use the following part: LA7D3064

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

                          The part number is as follows: 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.

                          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).
