The Allen-Bradley/Rockwell Automation 104-E370EN22 contactor is a 3-pole reversing contactor from the IEC 104 Contactors series and the 104-E contactor product line. The 3 poles that the 104-E370EN22 reversing contactor is equipped with are its 3 main contacts that it uses to connect to a power supply. In addition to these 3 main contacts, this reversing contactor also supports 2 built-in auxiliary contacts. The 2 auxiliary contacts include 1 NO or Normally Open contact and 1 NC or Normally Closed contact. The 104-E370EN22 reversing contactor is commonly used with AC-1, AC-2, or AC-3 motors that have different voltage ratings. When it operates with AC-3 motors at an ambient temperature of 140 degrees Fahrenheit, the 104-E370EN22 reversing contactor supports a current rating of 370 Amps at a voltage rating of 400 Volts.

Additionally, when the Allen-Bradley IEC 104 series 104-E370EN22 3-pole reversing contactor operates with AC-1 motors at an ambient temperature of 104 degrees Fahrenheit, it supports a current rating of 600 Amps at a voltage rating of 690 Volts. When the 104-E370EN22 reversing contactor is used in switching applications with AC-2 and AC-3 types of motors, it can support a kilowatt output rating of up to 315 kilowatts at a voltage rating of 690 Volts with 50 Hertz frequency, and it can support a Horsepower output rating of up to 350 Horsepower at a voltage rating of 575 Volts at 60 Hertz frequency. The electronic coil for the 104-E370EN22 reversing contactor has the highest AC/DC coil voltage rating available in the IEC 104 Contactors series. This contactor’s coil voltage rating is 250 to 500 Volts AC/DC with 50 to 60 Hertz frequency for the AC voltage.
