              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. 

              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 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.


              Contactor LE1D18N7 does it come with overload ?

               No - Overloads can be ordered separatly depending on the current rating required

              What is the plastic arm for LE1D18U7 stop button

              Part code LAD91810

              IThe maximum voltage per UL and CSA is 600VAC. 

              What is the part number for a DOL starter for 7.5kW load with 415VAC coil and overload for 16amps?

              The part number for a DOL starter for 7.5kW load with overload for 16amps is - LE1D18N7 & LRD21
