The 100-D140ZT22L contactor is a Bulletin 100-D series IEC contactor which has been designed and manufactured by Allen-Bradley/Rockwell Automation. The 100-D140ZT22L IEC contactor is available in a reversing version and a non-reversing version. Both versions of the contactor come with built-in auxiliary contacts that include late-break contacts, and both versions operate with DC-powered conventional coils. The reversing version of the 100-D140ZT22L IEC contactor can be used to reverse the flow of AC voltage in industrial AC motors, but the non-reversing version of the contactor cannot. The DC-powered conventional coils that the 100-D140ZT22L IEC contactor uses need to connect to all of the late-break normally closed auxiliary contacts on the contactor. The coil connects to the late-break contacts through its pickup winding.

Both the reversing and the non-reversing versions of the Allen-Bradley/Rockwell Automation 100-D140ZT22L Bulletin 100-D IEC contactor have 3 main contacts. The non-reversing 100-D140ZT22L IEC contactor has 2 normally open auxiliary contacts, 1 standard normally closed auxiliary contact, and 1 late-break normally closed auxiliary contact. The reversing 100-D140ZT22L IEC contactor has 2 normally open auxiliary contacts, 2 standard normally closed auxiliary contacts, and 2 late-break normally closed auxiliary contacts. Both versions of the 100-D140ZT22L IEC contactor can be used to switch AC-2 and AC-3 motors with either kilowatt output or Horsepower output. The 100-D140ZT22L IEC contactor’s maximum Horsepower output rating for switching AC-2 and AC-3 motors is 125 Horsepower at a rated voltage of 575 Volts and a rated frequency of 60 Hertz. Its maximum kilowatt output rating for switching AC-2 and AC-3 motors is 111 kilowatts at a rated voltage of 690 Volts and a rated frequency of 50 Hertz.
