Allen-Bradley 505-AAXD-3-102 Reversing Contactor

The Allen-Bradley 505-AAXD-3-102 Reversing Contactor is a three-pole, full-voltage reversing starter from the Bulletin 505 family that provides forward and reverse motor control in industrial automation setups. It combines a three-pole main contactor with an integrated overload relay and a 120 VAC coil, enabling reliable bidirectional operation from a single control circuit. Sized for a size-3 configuration, this unit is designed for compact control panels and motor loads that require frequent direction changes, while maintaining standard wiring practices used in typical 3-wire reversal schemes. The overload relay protects the connected motor by monitoring current and interrupting the circuit if an overload condition is detected, helping to guard equipment and extend service life. Common applications include conveyors, packaging lines, machine tools, and process lines where reversing a single motor is required for operation or material handling. As part of the Allen-Bradley 505 line, the 505-AAXD-3-102 is built to integrate with other 505 components to support cohesive protection and control schemes across control panels and industrial equipment.
