The 104-E146KY22 contactor is an IEC 104 series reversing contactor manufactured by Allen-Bradley/Rockwell Automation. It meets the IEC (International Electrotechnical Commission) standards and it is used in industrial applications such as elevators, HVAC, power transformers, and 3-phase motor applications. The Allen-Bradley 104-E146KY22 contactor is a modern contactor that is designed to use less coil power than standard legacy contactors. It has AC-3 and AC-1 IEC utilization category ratings. It has an AC-3 current rating of 146 Amps at 400 Volts and 60 degrees Celsius, and an AC-1 current rating of 225 Amps at 690 Volts and 40 degrees Celsius. The 104-E146KY22 reversing contactor is equipped with a standard electronic coil that provides both AC and DC control. The electronic coil has a control voltage range between 48 Volts and 130 Volts DC and 48 Volts and 130 Volts AC with an AC frequency rating of 50 or 60 Hertz. The 104-E146KY22 contactor's electronic coil has a built-in surge suppressor circuit that protects the coil from high voltage spikes.

The Allen-Bradley/Rockwell Automation 104-E146KY22 IEC 104 series reversing contactor is a large frame type of reversing contactor that has 3 main poles or main contacts. It also has 2 auxiliary contacts, one of which is normally open or N.O. and the other of which is normally closed or N.C. It includes a mechanical interlock for linking the 2 auxiliary contacts of 2 contactors. The 104-E146KY22 contactor has a maximum operating power rating of 75 kilowatts at 1000 Volts and 60 degrees Celsius. It also has a maximum 3-phase Horsepower rating of 125 Horsepower at 575 Volts AC and 60 Hertz and a general-purpose current rating of 200 Amps as per the UL/CSA standards. The 104-E146KY22 reversing contactor has a rated impulse withstand voltage of 8 kilovolts.
