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 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 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.
Looking for a LC1D50A.. with a 240v coil
Part code is LC1D50AU7
Do the Everlink reversing contactors come with electrical interlocking?
Issue:
Electrical interlock kit for the LC1D65A Everlnk contactors.
Product line:
Tesys D LC1D40A, LC1D50A, LC1D65A
Environment:
Everlink, all voltage codes
Cause:
Old D2 version offered an electrical interlock kit
Resolution:
The current Everlink version does not offer an electrical interlock kit. The customer can wire electrical interlocking using the normally closed contacts provided on the contactor.
