The 100-D140EG11 contactor has been designed by Allen-Bradley from the Bulletin 100-D product line of the Allen-Bradley/Rockwell Automation IEC 100 Contactors series. It has the 3 main contacts that are standard on all of the Bulletin 100-D contactors, and it also has built-in auxiliary contacts that are not standard features on every Bulletin 100-D contactor. The built-in auxiliary contacts include a normally closed auxiliary contact and a normally open auxiliary contact. If more auxiliary contacts are required, they can be added to the 100-D140EG11 contactor in the form of side-mounted auxiliary contact blocks. The 100-D140EG11 contactor uses its auxiliary contacts to make a variety of auxiliary connections while it uses its main contacts to make power connections. The power connections connect it to its operating power source to allow it to function.

The Allen-Bradley 100-D140EG11 contactor from the IEC 100 and Bulletin 100-D product series is one of the Bulletin 100-D contactors that has an electronic coil instead of a conventional coil. Because it has an electronic coil, the 100-D140EG11 contactor can operate with an EI or electronic interface. This interface allows the contactor to handle advanced control options and applications that other Bulletin 100-D contactors with conventional coils cannot handle. The coil voltage rating for the 100-D140EG11 contactor’s electronic coil is 200 Volts AC or 200 to 220 Volts AC at 50 to 60 Hertz operating frequency. The rated storage temperature range for the 100-D140EG11 contactor is from -40 to 80 degrees Celsius and its rated operating temperature range for normal operation is from -25 to 60 degrees Celsius.
