The 104-E400EJ22 contactor is a reversing contactor which is manufactured and distributed by Allen-Bradley/Rockwell Automation. This contactor comes from the 104-E product line within the IEC 104 series of contactors. This contactor is designed with compact dimensions that allow it to meet the needs of almost any application that has significant installation space limitations or that requires very compact equipment. This contactor comes with electronic coils that can cover a wide voltage range and that operate with low power pick-up and hold-in current ratings. It operates with 1 normally open and 1 normally closed auxiliary contact and with 3 normally open main contacts. This contactor has a Standard AC/DC with PLC Input of 24-60 Volts AC and 20-60 Volts DC. The 104-E400EJ22 reversing contactor can be ordered with a PLC interface for certain applications. However, if this PLC interface is ordered, its use is mandatory. If the PLC is not needed, there is no need to order it with the contactor. 

The Allen-Bradley/Rockwell Automation 104-E400EJ22 IEC 104 and 104-E series reversing contactor operates with a maximum current of 600 Amps at a maximum ambient temperature of 40 degrees Celsius or 104 degrees Fahrenheit, and it operates with a maximum current of 400 Volts at a maximum ambient temperature of 60 degrees Celsius or 140 degrees Fahrenheit. The 104-E400EJ22 reversing contactor is able to operate with a reversing mechanism that allows it to reverse an industrial motors voltage flow or polarity in advanced applications, and as a result, it is used mainly with industrial motors that are able to operate with reversed polarity or voltage. There is also a wide range of accessories that are available for customizing the 104-E400EJ22 reversing contactor so that it can operate with the highest possible level of efficiency and flexibility in the widest possible variety of applications.
