Allen-Bradley 100-C Contactors

Allen-Bradley 100-C IEC contactors are compact three-pole devices used for motor starting and general power switching on industrial panels. Catalog numbers decode in a fixed order: after the 100-C prefix comes the amp frame (09, 12, 16, 23, 30, 37, 43 and similar), then a coil voltage letter such as D, EJ, or KJ, and finally the auxiliary contact digits—for example 10 for one normally open contact. Confirm amp frame and coil code against the failed unit or the motor nameplate before you reorder. East Coast Compactor keeps common 100-C sizes on the shelf and ships from Northwood NH. We are an independent parts supplier, not an authorized Rockwell distributor, and we do not claim manufacturer warranty coverage.
