Allen-Bradley 509-BOD-XXX Nema Size 1 120V Coil Starter

Allen-Bradley 509-BOD-XXX NEMA Size 1 Full-Voltage Non-Reversing Starter with a 120 V coil, Open Type (without enclosure). This Bulletin 509 device provides direct-on-line motor starting with built‑in overload protection in a compact, open-frame package and is designed for use with Allen-Bradley Bulletin 500 motor control assemblies. The coil is rated for 115–120 V AC at 60 Hz, and the starter is specified for up to 27 A full-load current on a 600 VAC, three‑phase circuit. An eutectic alloy overload relay is integrated to protect connected motors, making it suitable for small to mid‑size three‑phase applications such as conveyors, pumps, and fans where a simple, robust starter is required. The 509-BOD-XXX is non-reversing, delivering a fixed starting direction, and its open construction simplifies installation in surface-mounted control panels or enclosures where space is at a premium.
