Allen-Bradley 509-COD-A2H Full Voltage Non-Reversing Starter

Allen-Bradley 509-COD-A2H Full Voltage Non-Reversing Starter is an open-type NEMA motor starter from Rockwell Automation designed to energize three-phase motors at full line voltage with non-reversing operation. It belongs to the 509-COD family and is intended for panel mounting without an enclosure, typically used with a compatible overload relay to protect the protected motor. In the Size-2 configuration common to this family, similar variants list a coil voltage around 115–120 V AC at 60 Hz and a nominal full-load current range in the 11–55 A class, though exact values depend on suffix and options. This starter is suited for straightforward on/off control of motors in industrial environments and finds use in applications such as conveyors, pumps, fans, and machine tools where motor direction reversal is not required.
