The 100-D180EJ11 contactor is an IEC contactor which has been designed by Allen-Bradley/Rockwell Automation and which is available from the Allen-Bradley Bulletin 100-D contactors series. All of the Bulletin 100-D contactors like the 100-D180EJ11 contactor are environmentally friendly devices because they are compact and efficient, because they can be easily customized with special accessories for special applications, and because several of their key standard components are replaceable. The 100-D180EJ11 contactor has been designed for maximum efficiency and flexibility and to reduce industrial waste. It has 3 normally open main contacts that provide its power supply connection and which are all replaceable so that it is not necessary to dispose of and replace the entire contactor on account of just 1 small faulty part.

The Allen-Bradley/Rockwell Automation 100-D180EJ11 Bulletin 100-D IEC contactor has 2 auxiliary contacts as standard features in addition to its main contacts. One auxiliary contact is NO or normally open like all of the main contacts and the other auxiliary contact is NC or normally closed. The 100-D180EJ11 contactor is a non-reversing contactor, and this means that it cannot be used with AC motors that need to have their voltage flow reversed in the course of an application. This IEC contactor uses an electronic coil that supports an electronic interface. The coil voltage rating is 24 Volts AC with 50 to 60 Hertz frequency, and the insulation that protects the coil is Class B insulation. The normal operating temperature range for the 100-D180EJ11 contactor is from -13 to 140 degrees Fahrenheit, but if its current rating is reduced by 15% or more, the contactor can operate at up to 158 degrees Fahrenheit.
