        What suppressor do I need for a LC1DT40 contactor 110Vac

        You need to use a LAD4RCU - RC circuit suppressor 110-240Vac.

        Will a LAD4RCE or LA4DRCU also fit a LC2D09 thru LC2D38 reversing contactors?

        Issue:
        Identifying accessories for reversing contactors

        Product Line:
        IEC contactors and starters

        Environment:
        Products sold and used in the United States

        Cause:
        Accessories used on non-reversing contactors are also needed for reversing application

        Resolution:
        Yes, the LC2D contactors are provided standard with one on the left contactor. One may be added to the right contactor.


        CTA-ID : 2022733

        Are the LAD4 RC suppressors CE marked?

        Product Line:  
        Tesys D line Contactors and Accessories

        Resolution:
        Yes these are CE marked.

        Issue:
        AC coil replacement for CAD32 and CAD50

        Product Line:
        Relays

        Environment:
        Tesys CAD Control Relays

        Cause:
        Product selection

        Resolution:

        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:
        Part number for the mechanical interlock for a 4 Pole contactor LC1DT80A__?

        Product Line: 
         Contactors and Starters - IEC

        Environment:
        LC1DT80A

        Cause:
        Needs the mechanical interlock for a 4 Pole contactor LC1DT80A__.

        Resolution:
        LAD4CM

        Is it possible to mount a surge suppressor with LED (LAD4RCE) on the CA4KN**, low consumption DC control relay.

        CA4KN** control contactor comes fitted with integrated surge suppressor (bidirectional diode), thus there is no need for an external surge suppressor.
         
        However if the additional surge suppressor on the CA4KN22** is required, then it is possible to mount the suppressor (LAD4RCE).
         
        If the additional surge suppressor with LED is being used just for indication to verify that power is applied to the contactor, it is advisable to use a normal LED as per the coil voltage, connected to the coil supply (A1- A2).
         
        This will give the indication functionality as that of the additional external surge suppressor with LED, if that is what the only requirement is.

        Can I use a LA9D6569 reversing kit with LC1D40AU7 contactors

        No, correct kit is a LAD9R3.

        What is the interlock for LCD18

         The part code is LAD9R1V

        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.

         

        Need a LC2D323U7 reversing contactor

        Use 2 x LC1D32U7 with a LAD9R1V reversing wiring kit

        What is the part number of the mechanical link for reversing contactors LC1D25U7

        LAD9R1V
