Allen-Bradley 509-AAA-A2F NEMA Size 0 Motor Starter

The Allen-Bradley 509-AAA-A2F is a Bulletin 509 NEMA full-voltage non-reversing (FVNR) magnetic motor starter from Rockwell Automation, built on a NEMA Size 0, 3-pole contactor rated 18 A continuous (21 A service limit) at up to 600 Vac, with a 230/240 Vac, 60 Hz coil (220 Vac, 50 Hz). It pairs the contactor with a solid-state overload relay offering a Class 20, 3.2–16 A adjustable trip range, housed in a Type 1 (NEMA 1) general-purpose, surface-mounting enclosure. Starters in this Size 0 family are rated up to 5 Hp at 575 Vac, 3-phase, and are typically applied for across-the-line (DOL) starting of motors in pump, fan, conveyor, and general industrial motor-control applications.

Within Rockwell's Bulletin 509 catalog structure, the 509-AAA base code designates a Size 0, Type 1 enclosed starter with a 230/240 Vac, 60 Hz coil, and the -A2F suffix specifies the solid-state overload relay fitted to it, adjustable across 3.2–16 A.
