The 104-E305KJ22 reversing contactor is a 3-pole AC and DC-operated reversing contactor that has been included in the Bulletin 104-E line of Allen-Bradley IEC 104 series reversing contactors. Contactors are similar to switches and relays, with the main difference being that contactors have been designed to operate in heavy-duty applications that include the use of motors. The Allen-Bradley/Rockwell Automation 104-E305KJ22 3-pole AC and DC-operated reversing contactor operates with AC and DC coil voltage, and this standard coil voltage ranges from 24 to 60 Volts AC at 50 to 60 Hertz and 20 to 60 Volts DC. This contactor also operates with a current rating of 500 Amps at a steady ambient operating temperature of 40 degrees Celsius. The Allen-Bradley/Rockwell Automation 104-E305KJ22 3-pole AC and DC-operated reversing contactor can be installed in an environment with an ambient temperature range of -40 to 70 degrees Celsius and in a location that does not exceed 3000 meters in altitude. 

The Allen-Bradley/Rockwell Automation 104-E305KJ22 3-pole AC and DC-operated reversing contactor can be installed both on a DIN Rail and on a panel if required. For applications that have high levels of vibrations and shock, it is recommended to install this contactor on a panel. The Allen-Bradley/Rockwell Automation 104-E305KJ22 3-pole AC and DC-operated reversing contactor come with coils that are designed to reduce the pick-up current. This reduction can be as much as 80 percent in most cases. The holding current is also reduced with this feature. This contactor can also be ordered with an optional PLC interface that improves its control functions. This contactor comes with one N.O. and one N.C. built-in auxiliary contact and more auxiliary contacts can be added if necessary. There is an accessories catalog with add-on parts that can be selected to improve and customize the functioning of the contactor.
