The 104-E146ED22 contactor is a 3-pole reversing type of contactor that can support AC and DC voltage. The 104-E146ED22 reversing contactor has been designed and manufactured by Allen-Bradley/Rockwell Automation, and it is part of the Bulletin 104-E product line in the Allen-Bradley IEC 104 Contactors series. Its 3 poles are 3 normally open main contacts, and they are accompanied by 1 normally open auxiliary contact and 1 normally closed auxiliary contact for a total of 5 built-in contacts. The 104-E146ED22 reversing contactor is often used in applications with AC-1, AC-2, or AC-3 types of motors with a variety of voltage ratings. This contactor can operate with 400-Volt AC-3 motors at a maximum operating current of 146 Amps and an ambient temperature of 140 degrees Fahrenheit, and it can operate with 690-Volt AC-1 motors at a maximum operating current of 225 Amps and an ambient temperature of 104 degrees Fahrenheit.

The Allen-Bradley/Rockwell Automation 104-E146ED22 3-pole reversing contactor from the IEC 104 Contactors series can operate in tandem with another contactor if they are connected with a mechanical interlock. With a mechanical interlock, the 104-E146ED22 reversing contactor’s dimensions are approximately 6 x 7 x 5 inches or 150 x 180 x 126 millimeters (excluding the dimensions of the other contactor.) The standard AC/DC electronic coil that the 104-E146ED22 reversing contactor uses supports voltage ranges between 100 and 250 Volts AC with 50 to 60 Hertz frequency and 100 and 250 Volts DC. This contactor is also available with a special electronic coil that supports the same coil voltage ratings but that also has an input for a PLC for applications that require logic.
