              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. 

              Can the LE1D and LE2D enclosed Tesys D-Line contactors be obtained with DC control coils?

              What is the altitude derating for a TeSys D-Line contactor?

              What is the altitude derating for a TeSys D-Line contactor?

              Product Line:
              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.

              All AC coils for the LC1D09 through LC1D38 3-pole contactors ( including ring tongue, quick connect and spring terminal versions ) have an inrush of 70 volt-amps for either 50 or 60 Hertz applications, and a sealed value of 7 volt-amps for 50Hertz applications or 7.5 volt-amps for 60 Hertz applications.

              What is the overload to suit LE3D12N7 star delta starter?

              Overload to suit LE3D12N7 will be either LRD12, LRD14 or LRD16 depending on application.

              What is the maximum UL/CSA AC voltage rating of the LC1D power contacts ?
