                Tesys D line Contactors and Accessories

                Resolution:
                 
                Mounting this module to TeSys LC1D40A through LC1D65A contactor requires the use of the LAD4BB3 wiring adaptor. This adaptor can be fitted only to contactors with no coil suppressor.
                 

                Will the LA4DC1U work with the new CAD32BD relay?

                Issue:

                Product Line:
                IEC relays and accessories

                Environment:
                Products sold and used in the United States

                Cause:
                Identifying product compatibility

                Resolution:
                The CAD32BD with DC coil has built-in coil suppression protection as standard so the LA4DC1U is not needed.

                Will the LA4DC1U diode suppressor mount to current Tesys D DC coils?

                Issue:
                Will the LA4DC1U diode suppressor mount to current Tesys D DC coils?
                Product Line:
                IEC contactors and starters

                Environment:
                Products sold and used in the United States

                Resolution:
                No. The LA4DC1U diode unit will only fit the older TeSys D contactors. Tesys D DC coils include suppression automatically, it`s not needed.

                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

                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.

                Is the voltage code BD3 valid for a CA3DN40 relay?

                Issue:
                Is the voltage code BD3 valid for a CA3DN40 relay?

                Product Line:
                Tesys Relays

                Environment:
                All Products

                Cause:
                Product selection

                Resolution:
                No.  The voltage code BD3 is for the CA4D Low Consumption relays only.   A 24 volt DC coil with built in transient suppression is not available on the CA3D relay.    Use the add on LA4DA1E varister style or the LA4DC1U diode style add on transient suppressors on the CA3D relays.
                 

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

                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

                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.

                What suppressor do I need for a LC1DT40 contactor 110Vac

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

                What is the replacement for LA1DN40?

                The replacement for LA1DN40 is LADN40

                LADN40
