        Frequently Asked Questions

        hide show

        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.

        What suppressor do I need for a LC1DT40 contactor 110Vac

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

        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.

         

        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. 
         

        Are the LAD4 RC suppressors CE marked?

        Product Line:  
        Tesys D line Contactors and Accessories

        Resolution:
        Yes these are CE marked.
         

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

        Issue:
        AC coil replacement for CAD32 and CAD50

        Product Line:
        Relays

        Environment:
        Tesys CAD Control Relays

        Cause:
