104-E146KN22

The 104-E146KN22 contactor is a 3-pole reversing type of contactor that has been designed by Allen-Bradley/Rockwell Automation and included in the IEC 104 and Bulletin 104-E series of connectors. This contactor device is somewhat similar to the relays and electrical switches that turn machines on and off when the power is applied to the coils. Contactors are normally used in more demanding applications that include motors and the 104-E146KN22 contactor is used specifically if there is the need to reverse the voltage or polarity of a specific motor. This contactor comes ready to operate in this mode without the need for additional equipment such as pushbuttons. The Allen-Bradley/Rockwell Automation 104-E146KN22 3-pole reversing contactor does not include built-in terminal lugs but they can be ordered from the accessories catalog. This contactor can also be ordered with an optional PLC interface that provides different control features to the contactor.

The Allen-Bradley/Rockwell Automation 104-E146KN22 3-pole reversing contactor employs a voltage range of 250 to 500 Volts AC and DC. Before selecting this contactor, the features that it has must be noted carefully to ensure that it is compatible with the motor and overall application that it will be used for. The maximum current rating that the Allen-Bradley/Rockwell Automation 104-E146KN22 3-pole reversing contactor can handle at a temperature of 40 degrees Celsius is 225 Amps. The contactor comes with one N.O. auxiliary contact and with one N.C. auxiliary contact. More contacts can be added to the contactor through contact blocks. This contactor also has 3 main contacts which are all N.O. poles. The installation process of the Allen-Bradley/Rockwell Automation 104-E146KN22 3-pole reversing contactor is simple and it only requires that the wiring and connections are done correctly. Incorrect wiring can cause disruptions and malfunctioning in the motor.
