        Frequently Asked Questions

        hide show

        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.


         

        Is there a remote electrical reset for F line contactors?

        Issue:
        Is there a remote electrical reset for F line contactors?
        Product Line:
        Tesys F contactors
        Environment:
        IEC Contactors
        Cause:
        Product Characteristics
        Resolution:
        Yes. The part number for the remote electrical reset snap-on module is LA7D03x, where x represents the coil voltage code.
        Voltage Codes:
        AC: 24V – B, 48V – E, 110V – F, 220/230V – M, 380/400V – Q, 415/440V - N          
        DC: 12V – J, 24V – B, 48V – E, 96V – DD, 110V – F, 220/230V - M

        What D-line overload relays use the LA7D3064 separate mounting kit?

        Issue
        What D-line overload relays use the LA7D3064 separate mounting kit?

        Product Line
        Overload relay

        Environment
        Tesys and Pre Tesys D-line

        Cause
        Fit, compatibility, and product features 

        Resolution
        The LRD3***   LR3D3**, LR2D35** D-line overload relays.

        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 LA4DE1U alternative?

        LA4DE1U TeSys D - suppressor module - varistor - 110...250 V AC/DC

        to suit D40-D115 (3P) and D65-115 (4P):
        LA4DE2U TeSys D - suppressor module - varistor - 110...250 V AC
        OR
        LA4DE3U TeSys D - suppressor module - varistor - 110...250 V DC
         

        Will the LA7D1064 fit the new TeSys LRD overload relays?

        Issue:
        Identifying separate mount for newer style LRD overload relays

        Product Line:
        IEC contactors and starters

        Environment:
        Products sold and used in the United States

        Resolution:
        No, they are a different design and will not work with the Tesys overload relays, you will need the LAD7B10 or LAD7B10..

        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

        Is the voltage code BD3 valid for a CA3DN40 relay?

        Issue:
        Is the voltage code BD3 valid for a CA3DN40 relay?

        Product Line:
        Tesys Relays

        Environment:
        All Products

        Cause:
        Product selection

        Resolution:
        No.  The voltage code BD3 is for the CA4D Low Consumption relays only.   A 24 volt DC coil with built in transient suppression is not available on the CA3D relay.    Use the add on LA4DA1E varister style or the LA4DC1U diode style add on transient suppressors on the CA3D relays.
