Allen-Bradley 100-C09D400 4 Pole AC Contactor

Allen-Bradley 100-C09D400 is a four-pole IEC contactor (Bulletin 100-C) with four normally open power contacts and screw-terminal line-side connections, purpose-built for dependable motor switching in industrial control panels. It is coil-driven by 120 VAC in typical 60 Hz North American service (the 100-C family also includes 110 VAC/50 Hz variants), and it is rated for up to 9 A in AC-3 service for starting and stopping squirrel-cage motors and similar loads. As a 4-pole device, it can switch all four conductors of a three-phase circuit, simplifying wiring with clearly labeled line-side terminals. Optional front- and side-mounted auxiliaries can be added for signaling, interlocking, or feedback in more complex control schemes. The 100-C09D400 is designed to deliver reliable, compact motor-control performance in manufacturing environments, supporting common applications such as conveyors, pumps, and fans where remote coil control and robust switching are required.
