Allen-Bradley 100-C09D10 Contactor 3-Pole With Auxiliary Contacts

Allen-Bradley 100-C09D10 is a three-pole IEC contactor with a 24 VDC coil and a built-in normally open auxiliary contact, designed to switch three-phase loads in control panels. It uses line-side screw terminals for straightforward wiring and is part of the Bulletin 100-C family, a compact, space-saving solution for motor control. Rated for AC-3 duty at up to 9 A with a maximum main contact rating of 600 VAC, it is suitable for starting small motors, pumps, or fans in 50/60 Hz systems, while a 24 V DC control signal energizes the coil. The single normally open auxiliary contact provides basic feedback or interlock functionality in simple control circuits, enabling reliable integration with PLCs or timers without needing extra relays. This DC-coil variant is built for standard industrial environments where a compact, single-pack contactor is required to coordinate a DC control circuit with a three-phase load.
