Allen-Bradley 509-BOD Size 1 is a NEMA full-voltage non-reversing motor starter with an open-type enclosure and an overload relay using eutectic alloy protection, designed for 3‑phase motors. It is driven by a 115–120 V AC, 60 Hz coil to switch line voltages up to 600 VAC, with 7.5 HP at 200–230 VAC and 10 HP at 460–575 VAC. Sold as an open-type starter for installation without a dedicated enclosure, it features a mechanical life of 10 million operations and is commonly used in compact industrial panels to start and stop small to mid-size motors such as pumps, fans, conveyors, and process equipment.
