Note: A contactor with an AC coil can be changed to a different AC voltage coil, IE you can take an LC1D09 with a 120VAC coil and put a 24VAC coil in it instead. An AC device cannot be switched to a DC coil, and a DC device cannot be switches to an AC coil.
Where are the control coil terminals for TeSys LC1D09 to LC1D38 contactor?
Issue:
Determine the control coil terminal marking and location on LC1D09 to LC1D38 contactor
Product Line:
Tesys D Contactors
Environment:
IEC contactors
Resolution:
The coil terminals are marked A1 and A2, you can see them on the front of the contactor on the white part (control section). They are next to the auxiliary contact (13/14, 21/22) terminals.
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.
What is the power terminal lug data for the LC1D09, LC1DT20, LC1D12, and LC1DT25 contactor?
Issue:
Power terminal lug data required for the 9 and 12 amp rated Tesys D contactors
Product Line:
IEC Contactors and Starters
Environment:
Tesys D Contactors
Resolution:
For contactors with screw clamp terminals:
stranded cable w/o cable end : One or Two #18-10 AWG per terminal.
stranded cable w/cable end: One or Two #18-10 AWG per terminal.
solid cable: One or Two #18-8 AWG per terminal.
What is the altitude derating for a TeSys D-Line contactor?
Issue:
What is the altitude derating for a TeSys D-Line contactor?
Product Line:
Digest 177 Section 18 : Contactors and Starters, IEC
Environment:
North American Products
Resolution:
The contactors are fully rated up to 3000 meters. Following are derating multipliers for altitudes above 3000 meters for both voltage and current:
Voltage
3500m x 0.90
4000m x 0.80
4500m x 0.70
5000m x 0.60
Current
3500m x 0.92
4000m x 0.90
4500m x 0.88
5000m x 0.86
For example, an LC1D80 at 5000 meters:
- The maximum rated operational voltage is 1,000V (IEC947-4) and 690V (UL/CSA). At 5000 meters it becomes 1000V x 0.6 = 600V (IEC947-4) and 690V x 0.6 = 414V (UL/CSA).
- The maximum rated operational AC3 current is 80A. At 5000 meters it becomes 80A x 0.86 = 68A.
What is the coil burden for the standard DC control coil for the LC*D09__ through LC*D38__ TeSys contactors?
Issue:
LC*D09-38 coil consumption
Product Line:
Contactors and Overload Relays
Environment:
TeSys™ D Contactors and Overload Relays
Resolution:
The standard DC coil is 5.4 watts of consumption.
