        Frequently Asked Questions

        hide show

        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. 
         

        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
        What D-line overload relays use the LA7D3064 separate mounting kit?

        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:
        Identifying differences between two similar part numbers.

        Product Line:
        IEC contactors and starters

        Environment:
        Products sold and used in the United States

        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).

         

        What is the LA4DE1U alternative?

        LA4DE1U TeSys D - suppressor module - varistor - 110...250 V AC/DC

        to suit D40-D115 (3P) and D65-115 (4P):
        LA4DE2U TeSys D - suppressor module - varistor - 110...250 V AC
        OR
        LA4DE3U TeSys D - suppressor module - varistor - 110...250 V DC
         

        Will the LA7D1064 fit the new TeSys LRD overload relays?

        Identifying separate mount for newer style LRD overload relays

        Product Line:
        IEC contactors and starters

        Environment:
        Products sold and used in the United States

        Resolution:
        No, they are a different design and will not work with the Tesys overload relays, you will need the LAD7B10 or LAD7B10..

        Can the old D-line front mount attachments fit on the new CAD relays?

        Issue: 
        Can the old D-line attachments fit the new CAD relays
         
        Product Line:
        IEC Contactors

        Environment:
        Tesys D contactors and relays
         
        Cause:
        Using old accessories with new CAD relays

        Resolution:
         Yes, the old style front mount latch attachments, timing attachments, and auxiliary contacts will mount on the new Tesys D-line relays.

        Does LC1D80BD have internal bi-directional diode?

        Issue:
        LC1D80 and LC1D95 bi-directional diode

        Product Line:
        TeSys™ D Contactors

        Environment:
        Contactor Accessories

        Resolution:
        LC1D80 and LC1D95 does not have an internal bi-directional peak limiting diode on their DC coils. LA4DC3U (Screw connection of wire to the contactor coil terminals 24–250 Vdc, 3p-4p) must be ordered separately.

        The LC1D09 to LC1D38 have an internal diode by default on their DC coils.

        How to use LRD01…35 LRD33•• & LRD43•• and LRD33** as an indepentent relay?

        The LRD relays has a solid tag to be used with LC1D** contactors. If you are not using LC1D contactors then using the following accessories you can terminate cable directly.

        For LRD01…35 use the following part: LAD7B106
        For LRD33•• & LRD43•• (3) use the following part: LA7D3064
