The 104-E190KD22 contactor is an IEC 104 series large frame reversing contactor developed by Allen-Bradley/Rockwell Automation. It is a highly durable and compact device used primarily in reversing single-phase or 3-phase motors in heavy-duty applications and in industrial settings. It has an operating current rating of 190 Amps and it is suitable for applications in the AC-3 utilization category. The 104-E190KD22 reversing contactor also has an AC-1 rating of 275 Amps. It is an IEC-certified electronic device that complies with the UL, CSA, CCC, and CE standards. This reversing contactor comes with a standard AC/DC operated electronic coil. The control voltage range for the electronic coil is 100 to 250 Volts AC and DC. The AC voltage has an operating frequency of 50/60 Hertz. There are 3 main poles and 2 auxiliary contacts on this reversing contactor. The auxiliary contacts are one normally open contact and one normally closed contact linked with mechanical interlocks.

The Allen-Bradley/Rockwell Automation 104-E190KD22 IEC 104 reversing contactor has operational current ratings of 275 Amps, 250 Amps, and 200 Amps at 690 Volts AC-1 and ambient temperatures of 40, 60, and 70 degrees Celsius, respectively. It has an AC-3 rated operational kilowatt output power of 90 kilowatts at 415 Volts AC and 50 Hertz. This reversing contactor also has an operating Horsepower rating of 125 Horsepower at a general-purpose current rating of 250 Amps and a 3-phase voltage rating of 460 Volts AC. It has bar connection terminals with conductor cross-sections ranging from 10 to 150 square millimeters for the main contact terminals. The maximum tightening torque recommended for the main contact terminal is 34 N-m. The 104-E190KD22 reversing contactor with a mechanical interlock has approximate dimensions of 196 millimeters in height, 210 millimeters in width, and 152 millimeters in depth.
