Allen-Bradley 100-C09E10 Contactor

Allen-Bradley 100-C09E10 is a three-pole IEC contactor rated at 9 A, designed to reliably switch three-phase motors in industrial automation environments. It uses a 380 VAC, 60 Hz control coil and includes one normally open auxiliary contact for signaling or interlocking in control circuits. The device supports flexible mounting options, with screw-terminal connections on the main contacts and mounting available on a base or a DIN rail for compact panel layouts or retrofit installations. In practical terms, the 9 A rating translates to roughly 2 HP at 230 VAC and about 5 HP at 460 VAC in typical three-phase service, enabling effective motor starting and protection in applications such as machine tools and conveyors. This model is part of Allen-Bradley’s 100-C/104-C family, built for industrial duty and compatibility with standard control circuits and protective devices used in motor control. Rockwell Automation lists 100-C09E10 as discontinued as of December 6, 2021, though remaining stock may still be available through distributors or secondary markets.
