The 100-D140EY00 contactor is a 3-pole type of IEC contactor from the Allen-Bradley Bulletin 100-D series. The 3 poles on the top of the 100-D140EY00 IEC contactor are its main contacts and they are accompanied by 2 built-in auxiliary contacts. If it needs more than 2 auxiliary contacts for any reason, they must be added onto it with auxiliary contact blocks from the Bulletin 100-D accessories catalog. The 100-D140EY00 IEC contactor can also be outfitted with interlocks, terminal lugs, and terminal shields for custom applications and for device protection, and it can have some of its components replaced when they wear out, including its arc chambers and its main contacts. The wide variety of spare parts and accessories that the 100-D140EY00 IEC contactor can accommodate make it flexible and environmentally friendly by increasing efficiency and reducing waste.

The Allen-Bradley Bulletin 100-D 100-D140EY00 IEC contactor can operate at -13 to 140 degrees Fahrenheit at its full power capacity. If its current capacity is reduced by 15%, it can operate at 140 to 158 degrees Fahrenheit, but this is only recommended in certain applications. When not in use, the 100-D140EY00 IEC contactor can be stored in a clean and dry environment at -40 to 176 degrees Fahrenheit. This contactor should not be used at altitudes higher than 2000 meters above sea level. This contactor can withstand up to 1000 Volts of isolation voltage according to the IEC standards, up to 690 Volts of isolation voltage according to the UL and CSA standards, and up to 12 kilovolts of isolation voltage according to the rated impulse voltage withstand standard.
