What is the power terminal lug data for the LC1D40, LC1D50, LC1D65, LP1D40, LP1D50, and LP1D65 contactor?
Issue:
Identifying power terminal lug data for the D2 style contactors
Product Line:
IEC Contactors and Starters
Environment:
Tesys D line contactors
Cause:
Power terminal lug data required
Resolution:
For contactors with screw clamp terminals:
stranded cable w/o cable end : One #10-3 AWG or Two #10-4 AWG per terminal.
stranded cable w/cable end: One #10-4 AWG or Two #12-2 AWG per terminal.
solid cable: One #10-3 AWG or Two #10-6 AWG per terminal.
What is the maximum UL/CSA AC voltage rating of the LC1D power contacts ?
Issue:
Identifying maximum voltage of an LC1D contactor
Product Line:
TeSys D Contactors
Environment:
IEC contactors and starters used in North America
Cause:
n/a
Resolution:
IThe maximum voltage per UL and CSA is 600VAC.
Are the D-Line contactors rated to break DC voltages?
Issue:
Can the TeSys D line be used to control DC loads?
Product Line:
Tesys D contactors
Environment:
Products sold and used in the United States
Cause:
DC power circuit
Resolution:
Yes, 75 VDC (125 VDC for D115 & D150) per pole which means that through a four pole device breaking 300 VDC is possible by wiring all four power poles in series. However, be aware that the device current ratings will differ according to the number of poles in series and the type of application.
Devices are suitable but not UL Listed for DC applications.
More information on their DC ratings can be found in the current TeSys Motor Control and Protection Compentns catalog: https://www.schneider-electric.us/en/download/document/MKTED210011EN/
Video: What auxiliary contact modules are available for the LC1D and LC2D contactors?

Product Line:
Contactor and Starters - IEC
Environment:
North American Products
Resolution:
Select based on application requirements. Please note that the TeSys and Pre-TeSys auxiliary blocks are backward/forward compatible.
