Frequently Asked Questions
Identifying maximum voltage of an LC1D contactor
TeSys D Contactors
IEC contactors and starters used in North America
IThe maximum voltage per UL and CSA is 600VAC.
What is the altitude derating for a TeSys D-Line contactor?
Digest 177 Section 18 : Contactors and Starters, IEC
North American Products
The contactors are fully rated up to 3000 meters. Following are derating multipliers for altitudes above 3000 meters for both voltage and current:
3500m x 0.90
4000m x 0.80
4500m x 0.70
5000m x 0.60
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.
Identifying power terminal lug data for the D2 style contactors
Tesys D line contactors
Products sold and used in the United States
Power terminal lug data required
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 electrical interlock kit for the LC1D65A Everlnk contactors
Tesys D LC1D40A, LC1D50A, LC1D65A
Everlink, all voltage codes
Old D2 version offered an electrical interlock kit
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.
Following are the differences between the LC1D50U7 and the LC1D50AU7:
LC1D50AU7 has everlink terminals.
LC1D50AU7....is slightly larger case and accommodate LRD3XX overloads
LC1D50U7 contactors accommodate LRD33XX overloads.
Mounting adaptor for GV2 and LC1D contactor
Motor Starters and Protectors
TeSys GV Manual Starter and Protectors
Tesys D Contactors
The GV2AF3 clip has to be moved to the DC position to accommodate the contactor with a DC coil.
Determine the control coil terminal marking and location on LC1D09 to LC1D38 contactor
Tesys D Contactors
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.
Two ways - the LC1D50AU7 can be DIN Rail mounted and Plate mounted.
See the attached datasheet for further information.
The mechanical interlock LAD4CM is the correct one for use with the LC1D50A••.
See attached datasheet for futher information on the LAD4CM.
