The Allen-Bradley 104-C85F22 Reversing Contactor is a 104 IEC series motor control contactor and it is specifically designed as a single motor starter that is capable of rotating the motor in both the forward and reverse directions. It comes from the factory as a contactor assembly that combines a set of 2 independent electromagnetic contactors into 1 device. The external 120 Volts AC signal is used by the Allen-Bradley 104-C85F22 Reversing Contactor to operate the motor that hosts in either the forward or reverse rotating directions, depending on the wiring and applications that have been selected by the final users. The rated power supply voltage for the  104-C85F22 Reversing Contactor is 230 Volts AC with a Horsepower output rating of 30 Horsepower, but the reversing contactor is also suitable for connection to a 460 Volts AC rated power source for a maximum Horsepower output of 60 Horsepower.

The Allen-Bradley 104-C85F22 Reversing Contactor needs to be powered with 3-phase voltage in both of its independent contactors, and each of them has 3 connection terminals of the screw type. A set of 4 auxiliary contacts is included in the Allen-Bradley 104-C85F22 Reversing Contactor, and 2 of them are normally open (NO) and 2 of them are normally closed (NC). The manufacturer recommends this contactor to be installed in a low-humidity and temperature-controlled panel in order to avoid the accumulation of dirt and moisture in the terminals and contact blocks and to avoid overheating. Contactors can be connected in the wye-delta, delta-wye, delta-delta, and wye-wye setups, giving the engineers a wide variety of control options so they can adapt the contactor to the specific application that it will control. Routine maintenance operations include terminal screw tightening, prevention of hot spots by thermal imaging inspections, and terminal/contact block cleaning.
