The 104-E190KJ22 contactor is a 190 Amps rated reversing contactor. It is part of the Allen-Bradley IEC 104 and 104-E series of reversing contactors. There are 3 poles and 2 auxiliary contacts on the device. The auxiliary contact configuration consists of 1 normally closed and 1 normally open auxiliary contact that work only with mechanical interlocks. The terminal type requires bar connections. The contactor is operated through a 24 to 60 Volts AC and 20 to 60 Volts DC rated electronic coil. The dimensions of the 104-E190KJ22 contactor are as follows: 196 millimeter in height, 105 millimeters in width, and 152 millimeters in depth. At 60 degrees Celsius and 400 Volts, the 3-phase AC current rating for the 104-E190KJ22 contactor is 190 Amps, and at 40 degrees Celsius and 690 Volts, the single-phase current rating for the contactor is 275 Amps.

The supported output power ratings for the Allen-Bradley 104-E190KJ22 reversing contactor at 50 Hertz for AC motors are as follows: 110 kilowatts at 1000 Volts, 132 kilowatts at 690 Volts, 110 kilowatts at 500 or 440 Volts, and 90 kilowatts at 415, 380 to 480, or 220 to 240 Volts. The supported output power ratings at 60 Hertz for AC motors are as follows: 150 Horsepower at 575 Volts, 125 Horsepower at 460 Volts, 60 Horsepower at 230 Volts, and 50 Horsepower at 200 Volts. The maximum recommended altitude of the installation site for the 104-E190KJ22 contactor is 3000 meters. The contactor complies with the resistance to shock requirements for the IEC 60068-2-27 standards. The contactor also complies with the resistance to vibration requirements for the IEC 60068-2-6 standards. The safe and reliable long-term operation of the contactor requires installation by trained technicians only.
