Allen-Bradley 100-C0910 Contactor

Allen-Bradley 100-C0910 Contactor is a three-pole IEC-style power contactor from Allen-Bradley (Rockwell Automation) used to switch three-phase motors in control panels. It features a 110/120 VAC coil and includes one normally open auxiliary contact (1NO) for signaling or interlock wiring. The device is rated for 9 A continuous load and carries a 4 kW power rating, making it suitable for light- to medium-duty motor control tasks. The 100-C family is designed for AC control circuits and accepts standard 100-C accessories for straightforward panel integration. Common applications include energizing and de-energizing three-phase motors in industrial automation equipment and control panels, where a compact, IEC-style contactor is advantageous. The coil voltage and contact arrangement align with typical control-supply setups in small-to-midsize automation installations, enabling simple integration with standard pushbuttons, interlocks, and control relays. As part of the 100-C family, it shares a common mounting approach and accessory ecosystem with other 100-C variants, simplifying replacements and retrofits in legacy systems.
