Allen-Bradley Contactors & Starters

Allen-Bradley contactors and starters here group IEC 100-C three-pole contactors, 104-C reversing contactors, and NEMA 509 / 500F open starters used for motor starting and power switching. IEC catalog numbers after 100-C or 104-C encode amp frame, coil voltage letter, and auxiliary digits; NEMA 509 and 500F sizes follow letter size codes such as AOD through EOD. Confirm amp rating and coil voltage against the failed unit or motor nameplate before you reorder. Narrower series pages for 100-C, 104-C, and 509 / 500F list the same stock when you already know the family. East Coast Compactor keeps frequently requested frames on the shelf and ships from Northwood NH. ECC is not an authorized Rockwell distributor and does not offer manufacturer warranty claims.
