The 104-E205KD22 contactor is an IEC 104 series reversing contactor that has been designed and manufactured by Allen-Bradley/Rockwell Automation. It has an operating current rating of 205 Amps for AC-3 duty applications. It is a next-generation reversing contactor that offers a smaller footprint than the legacy contactor versions. The 104-E205KD22 contactor is an eco-friendly electronic device that is RoHS compliant and meets the requirements of the UL, CE, and CSA standards. It supports switching for IE3 premium efficiency motors with output power levels ranging from 110 kilowatts to 160 kilowatts at voltages ranging from 220 Volts to 1000 Volts AC at 50 Hertz. It has an AC and DC-operated standard electronic coil with an operating voltage range of 100 Volts to 250 Volts AC/DC and an operating frequency of 50/60 Hertz for AC voltages. The electronic coil has a pick-up power rating of 130 Watts and a hold-in power rating of 2.5 Watts. The closing delay time of the coil is 25 to 60 milliseconds, and the opening delay time is 45 to 90 milliseconds.

The 104-E205KD22 reversing contactor belongs to the Bulletin 104-E line of IEC 104 contactors from Allen-Bradley. It includes 3 main contact poles and 2 auxiliary contacts. The auxiliary contacts include one N.O. contact and one N.C. contact with a mechanical interlock. It has operational AC-1 current ratings of 350 Amps and 275 Amps at 690 and 1000 Volts, respectively, at 50 Hertz AC and 40 degrees Celsius. The 104-E205KD22 contactor has a rated operational power of 110 kilowatts at 400/415 Volts, 132 kilowatts at 440/500 Volts, and 160 kilowatts at 690 Volts for switching 3-phase AC motors at 50 Hertz and 60 degrees Celsius. It supports up to 200 Horsepower rated 3-phase motors at a general-purpose current rating of 300 Amps per the UL/CSA specifications. The main terminals of the 104-E205KD22 contactor have conductor sizes ranging from 10 to 150 square millimeters.
