Allen-Bradley 705-BOB103 Size 1 Reversing Starter

Allen-Bradley 705-BOB103 Size 1 Reversing Starter is a motor-control device from Allen-Bradley’s Bulletin 705 family, designed for panel-mount installations in industrial automation. The 705-BOB103 configuration represents a Size 1 reversing starter, a compact solution for forward and reverse motor control within a single assembly. Exact electrical specifications—such as coil voltage, current rating, and enclosure compatibility—are determined by the chosen options for this part number; consult the official 705 product literature or your Allen-Bradley distributor for the specific configuration. The 705 family is historically used in control panels to simplify wiring and reduce component count when bidirectional motor control is required, and the 705-BOB103 identifies this particular unit in that lineup. When integrating this starter, ensure that the connected motor’s load and protection devices align with the device’s ratings and that wiring follows standard control-panel practices.
