The Allen-Bradley 104-E750EY22 Large Frame IEC Contactor is a 3-pole reversing AC/DC contactor that is designed for panel or DIN Rail mounting. The 104-E750EY22 Contactor has a standard type of AC/DC universal coil with a PLC interface. This PLC interface allows for the control and operation of the 104-E750EY22 Contactor via a logic control signal from a PLC. Its low switching power rating (24 Volts DC/10 milliamps) allows for easy PLC integration without the use of extra interposing relays. The 104-E750EY22 Contactor’s coil circuit has a wide coil voltage range to accommodate a wide range of applications. The coil voltage ranges from 48 to 138 Volts AC/DC at 50/60 Hertz coil frequency. The coil circuit also comes with Class F insulation that provides thermal insulation for up to 180 degree Celsius. The 104-E750EY22 Contactor’s main circuit supports reversing input connectivity.

The main circuit of the Allen-Bradley 104-E750EY22 IEC 104 Contactor has screw type terminals that accept AC/DC input voltage which ranges from 220 to 575 Volts AC and 24 to 440 Volts DC. It also has a high current capacity rating of 750 Amps at 400 Volts AC input and a maximum switching power rating of 400 kilowatts at 50 Hertz or 690 Volts AC inputs. The 104-E750EY22 Contactor has a rated isolation voltage of 690 Volts AC. Its circuits are designed to withstand up to 6000 Volts of peak voltage without failure. The 104-E750EY22 Contactor has 3-pole wiring, and it also comes with 4 additional auxiliary contacts (2 NO and 2 NC). The 104-E750EY22 Contactor features an IP2X ingress protection rating for its enclosure that prevents the operators from touching the internal components. It has a wide operating temperature range of -40 to 70 degrees Celsius and can be installed at a maximum altitude of 3000 meters.
