The Allen-Bradley 104-E370ED22 reversing contactor is a 3-pole type of contactor from the IEC 104 Contactors series that comes with 3 poles as its main contacts and that also features a built-in normally open auxiliary contact and a built-in normally closed auxiliary contact. The 104-E370ED22 reversing contactor can support either a standard electronic coil or a special version of the electronic coil that has an input for a programmable logic controller or PLC. A PLC interface is an essential device in certain contactor applications, but it is not required for the majority of standard contactor applications, and the special electronic coil that supports a PLC should not be ordered unless its usage with a PLC is guaranteed. Both the PLC version and the standard version of the 104-E370ED22 reversing contactor’s electronic coil support coil voltage ranges from 100 to 250 Volts AC/DC with AC frequency ratings of 50 to 60 Hertz.

The 104-E370ED22 reversing contactor from the Allen-Bradley IEC 104 Contactors series can be connected to another contactor with a mechanical interlock. The mechanical interlock allows the 2 contactors to operate in tandem. When the 104-E370ED22 reversing contactor is used for switching AC-2 and AC-3 motors, it supports different Horsepower and kilowatt output ratings depending on the voltage and frequency ratings. The 104-E370ED22 reversing contactor’s supported Horsepower ratings are 125 Horsepower at 200 Volts, 150 Horsepower at 230 Volts, 300 Horsepower at 460 Volts, and 350 Horsepower at 575 Volts and a frequency of 60 Hertz. Likewise, this reversing contactor’s supported kilowatt ratings are 200 kilowatts at 220 to 240 Volts, 380 to 400 Volts, 415 Volts, 440 Volts, and 1000 Volts, 250 kilowatts at 500 Volts, and 315 kilowatts at 690 Volts and a frequency of 50 Hertz.
