The 104-E460ED22 contactor is an IEC 104 and 104-E series reversing type of contactor from Allen-Bradley/Rockwell Automation. The highest current ratings that the 104-E460ED22 reversing contactor can support include 460 Amps of current with AC-3 motors that are rated for 400 Volts at an ambient temperature of 60 degrees Celsius or 140 degrees Fahrenheit, and 700 Amps of current with AC-1 motors that are rated for 690 Volts at an ambient temperature of 40 degrees Celsius or 104 degrees Fahrenheit. The 104-E460ED22 contactor has screw-type terminals, 3 main contacts that are known as poles, and 2 built-in auxiliary contacts. One of the auxiliary contacts is NC or Normally Closed while the other auxiliary contact is NO or Normally Open.

When the Allen-Bradley/Rockwell Automation 104-E460ED22 IEC 104 reversing contactor is used for switching AC-2 or AC-3 motors, it can work with AC-2 or AC-3 motors that are rated at up to 1000 Volts with a kilowatt output power rating of 280 kilowatts and a frequency rating of 50 Hertz. This reversing contactor can support a variety of kilowatt and Horsepower output ratings with AC-2 and AC-3 motors. The 104-E460ED22 reversing contactor’s highest supported kilowatt output is 280 kilowatts while its highest supported Horsepower output is 500 Horsepower, making it one of the most powerful reversing contactors in the IEC 104 and 104-E series. Its electronic coil supports coil voltage ranges from 100 to 250 Volts AC at 50 to 60 Hertz and 100 to 250 Volts DC. This electronic coil also allows the 104-E460ED22 reversing contactor to be connected to a PLC if a PLC is required by a specific application.
