What is difference between LC1D50U7 and LC1D50AU7?
Following are the differences between the LC1D50U7 and the LC1D50AU7:
LC1D50AU7 has everlink terminals.
LC1D50AU7....is slightly larger case and accommodate LRD3XX overloads
Whereas
LC1D50U7 contactors accommodate LRD33XX overloads.
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 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.
