        Frequently Asked Questions

        hide show

        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.


         

        Where can I find installation instructions for the LAD703 remote reset module?

        Issue:
        Installation and connection instructions for LAD703F

        Product line:
        Tesys D

        Environment:
        Remote reset module LAD703B LAD703F LAD703J LAD703E LAD703M LAD703Q LAD703N

        Cause:
        Documentation

        Resolution:
        See the attached instructions to mount the LAD703 onto the LRD style overloads.
        Apply wiring to the C1 and C2 terminals. 
        When the appropriate voltage is applied, the overload will reset.

        Are the LAD703F coils rated for continuous duty?

        Issue:
        Can you continuously press the reset button?

        Product line:
        Tesys D IEC Contactors and Overload Accessories

        Environment:
        LAD703 remote stop or electrical reset
        LA7D03 remote tripping or electrical reset

        Cause:
        Customer was using competitor brand and it burns after 10 seconds

        Resolution:
        The time for which the coil of the remote tripping or electrical resetting device, LAD703 or LA7D03 can remain energized depends on the rest time in between energizing the coil. 
        Minimum pulse to energize is 200ms

        1 second pulse needs a 9 second rest time
        5 second pulse needs a 30 second rest time
        10 second pulse needs a 90 second rest time
        Maximum duration of energizing the coil is 20 seconds and would require a 300 second rest time. 
         

        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

        In regards to LAD5C11 LAD5C31 LAD5C12 LAD5C32 What is the maximum kW range that TeSys SoLink can be used with motor starter combination?

        TeSys SoLink is the connection module to connect GV2/GV3 motor circuit breakers to associated contactors and can be used with GV2 / GV3 breakers up to 30kW.
