        Frequently Asked Questions

        hide show

        Are the LAD703F coils rated for continuous duty?

        Issue:
        Continuous duty on a LAD703F.

        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. 
         

        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 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
        LA7D3064 with LC1D compatibility

        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:
         LA7D305 and LAD7305 Difference

        Product Line:
        IEC contactors and starters

        Environment:
        LRD Accessories

        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).
