Bulletin 509 NEMA Starters

The Allen-Bradley Bulletin 509 is a family of NEMA-rated full-voltage non-reversing magnetic motor starters available across a wide range of sizes, enclosure types, and coil voltages, spanning 413 catalog numbers on this site. Starters are sized from Size 1 (e.g., 509-BAT, NEMA 1 general purpose) through Size 5 (e.g., 509-FCD-90, NEMA 4/4X stainless steel), with Size 3 and Size 4 units representing the broadest in-stock selection — including the 509-DHD (Size 3, NEMA 3R/7/9 bolted) and 509-EJD (Size 4, NEMA 3R/4/12 metal). Catalog numbers encode key configuration details: the letter(s) following 509- indicate NEMA size, the next character(s) identify the enclosure type (e.g., A = NEMA 1, J = NEMA 3R/4/12, H = NEMA 3R/7/9, C = NEMA 4/4X), and the trailing characters specify coil voltage (e.g., D = 110V/50 Hz, B = 480V/60 Hz, T = 400–415V/50 Hz, L = 208–240V/50–60 Hz). Suffix codes such as -90 denote reset options and -A2L indicate pilot device additions. Consult the Bulletin 509 NEMA Starters Technical Data (100-TD013) for full selection guidance and enclosure ratings.
