Allen-Bradley 100-C09UKJ10 Contactor

The Allen-Bradley 100-C09UKJ10 IEC 9 A Contactor is a three-pole, 24 VAC coil switch designed to reliably control small three-phase motors and other line-voltage loads in industrial control panels. It features screw-terminal connections on the load side and a 24 V AC coil rated for 50/60 Hz operation, suitable for standard industrial wiring. The device provides a single normally open auxiliary contact (1 NO) to support interlocking or signaling circuits and carries a load current rating of 9 A, enabling motor circuits up to 5 HP at voltages up to 600 V AC. As part of Allen-Bradley’s IEC contactor family, the 100-C09UKJ10 is commonly used to start and stop motors such as conveyors, pumps, and fans in panel assemblies, with a compact footprint that fits standard control enclosures. This model is the replacement for the earlier 100-C09UK10 and is manufactured by Rockwell Automation, ensuring compatibility with typical control transformers, overloads, and wiring practices in industrial environments.
