The 100-D110T11 non-reversing is a contactor that comes from the Bulletin 100-D/104-D series of reversing and non-reversing contactors by Allen-Bradley/Rockwell Automation. This contactor is one of the most compact contactors available in the industry. This contactor can be used in different applications, being the most common applications are safety applications that require feedback and hazardous motion load applications that contain energy isolating switchgear. The Allen-Bradley/Rockwell Automation 100-D110T11 contactor comes with one normally open and one normally closed auxiliary contact. These contacts give the contactor the mirror contact design that comes embedded in it. This feature helps to provide reliable indications about the status of the power poles which are the main contacts. When these poles are affected, the normally closed auxiliary contact will not modify its state, because it will remain isolated in the mirror contact setup.

Some of the key features that are included with the Allen-Bradley/Rockwell Automation Bulletin 100-D series 100-D110T11 contactor are an integrated PLC interface, a low power pick-up rating, and a low power hold-in rating, and the use of a wide voltage range. The voltage rating that is used by this contactor varies according to the frequency rating. With a frequency range of 50 to 60 Hertz, the voltage that is applied will range from 240 to 277 Volts AC. The Allen-Bradley/Rockwell Automation 100-D110T11 contactor operates with 3 power poles. This contactor is meant to be installed on a panel only. Since it has a compact design, it is somewhat easy to find a suitable installation location for it. It is not recommended to operate the contactor at its full rating at temperatures above 60 degrees Celsius. It can operate at up to 70 degrees Celsius if its current is derated.
