Allen-Bradley 509-BOD is a NEMA Size 1, full-voltage non-reversing motor starter with an eutectic alloy overload relay, designed for open-type installations without enclosure. It uses a 115–120 V AC, 60 Hz coil for control, and ships as a complete starter with overload protection integrated. This Rockwell Automation/Allen-Bradley unit combines motor-start control and thermal overload protection in a compact package suitable for direct-line motor control in 120 V control circuits.
