        Frequently Asked Questions

        hide show

        What is the part number for a varistor coil surge suppressor for a LC1D09 to LC1D32 3 pole and LC1DT20 to LC1DT40 4 pole?

        Issue:
        Surge suppressor part number is needed

        Product Line:
        TeSys D line Contactors

        Environment:
        Products sold and used in the United States

        Cause:
        Need a varistor coil surge suppressor in their application

        Resolution:
        For 24 to 48 volts AC LAD4VE, for 50 to 127 volts AC LAD4VG, and for 110 to 250 volts AC LAD4VU.
        These will limit the transient to 2 times nominal voltage and increases drop out time 1.1 to 1.5 times normal.

         

        Will the LAD4BB adapter work with a LC1D12BD contactor?

        Issue:
        Can we use the LAD4BB with the LC1D12BD?

        Product Line:
        IEC contactors and starters

        Environment:
        Products sold and used in the United States

        Cause:
        Identifying product compatibility

        Resolution:
        The LAD4BB will not work on the DC contactors, just the AC contactors.
         

        I have a LC1D12BD contactor and want to fit a LA4DFB to it

         You need to use a LAD4BB adaptor

        What is the difference between the LAD4TB and LAD4TBDL bi-directional peak limiting diode?

        Issue:
        Identifying the difference between LAD4TB and LAD4TBDL

        Product Line:
        IEC contactors and starters

        Environment:
        Products sold and used in the United States

        Cause:
        Identifying the difference between two similar part numbers

        Resolution:
        The LAD4TB is for 24V AC coils for the Tesys Series LC1D09 through LC1D38 contactors when supplied with G7 voltage code. The LAD4TBDL is 24 vdc bi-directional diode offered as a replacement if for some reason the diode supplied with the Tesys LC1D09 through LC1D38 contactors when ordered with BD or BL voltage code breaks or is no longer working.


         

        do the two little clips for connecting the contactors at the front that comes with the LAD9V2 come in the LAD9R1V?

        No They do not, and they are not available as a seperate part.

        What is the replacement AC coil for CAD32 and CAD50 relay?

        Issue:
        AC coil replacement for CAD32 and CAD50

        What mechanical interlock should I use with the LC1D50A••?

        The mechanical interlock LAD4CM is the correct one for use with the LC1D50A••.

        See attached datasheet for futher information on the LAD4CM.

        What is the mechanical interlock for a 4 Pole contactor LC1DT80A__?

        Issue:

        On a TeSys D or TeSys IEC relay, is there a top mounting provision that will allow you to relocate the A1 & A2 terminals from the right side to the top?

        Issue:
        On a TeSys D or TeSys IEC relay, is there a top mounting provision that will allow you to relocate the A1 & A2 terminals from the right side to the top?

        Product Line:
        TeSys D LC1D09-LC1D65A, TeSys IEC relay CAD**

        Environment:
        CAD, LC1D

        Cause:
        Assembly/wiring

        Resolution:
        The current TeSys IEC D line contactors ( LC1D09-LC1D65A) and the  TeSys IEC  Relay (CAD**) have A1 and A2 Terminals located on the right side of the device. To relocate the A1 & A2 Terminals, consider using the LAD4BB top-mounting wiring accessory.  Please note this device can only be used on the D line contactors or the IEC relays that are provided with AC coils. A mounting accessory for units with a DC coil is not available.
