Allen-Bradley 100-C09Z10A Three-Phase Contactor

Allen-Bradley 100-C09Z10A is a three-pole AC motor-contactor from Rockwell Automation’s 100-C family, engineered to switch a 3‑phase load at up to 460 V and drive motors up to 5 HP on 50/60 Hz systems. The unit provides three main power contacts (L1–L3 to T1–T3) for reliable motor control and is designed to be used as the power section of a motor starter when paired with compatible overload protection. This model is commonly configured with standard IEC-accessory options and is compatible with overload relays in the 193-series to form a complete motor starter assembly. Documentation and distributor listings for the 100-C09 family corroborate its 3‑pole configuration and 460 VAC capability, with a motor-rating profile that supports up to 5 HP for typical AC-3 motor control applications such as conveyors, pumps, fans, and machine tools. The 100-C09Z10A designation identifies a specific variant within the 100-C09 family used to control the device in automation circuits.
