Allen-Bradley 509-C0D Motor Starter

The Allen-Bradley 509-C0D Motor Starter is a three‑phase, full‑voltage, non‑reversing motor starter with built‑in overload protection for industrial AC motors and is part of the Bulletin 509 series. It’s a NEMA Size 2, 3‑pole, open type starter intended for panel mounting and rated for up to 45 A continuous current and a maximum 600 VAC, making it suitable for conveyors, pumps, compressors, fans, and other manufacturing equipment that require reliable motor starting and thermal overload protection. It uses a CC236 coil available in 110 V AC (50 Hz) or 120 V AC (60 Hz) and pairs with a Bulletin 592‑C0W16 thermal overload relay to guard the motor. Typical legacy replacements include the 509‑DOD non‑reversing starter and the 500F‑COD930 contactor, and the unit supports auxiliary contact compatibility with the 595 Series.
