Allen-Bradley 73A113U Three-Phase AC Contactor

Allen-Bradley 73A113U is a three-pole AC contactor from Rockwell Automation designed to switch three-phase motor loads in industrial control systems. The unit uses a 208 V AC coil rated for 60 Hz, enabling direct interfacing with typical 208 V control circuits and PLC outputs. As part of the 73A family, the contactor provides dependable, three-pole switching for line-side connections and can be paired with standard Allen-Bradley auxiliary contacts and accessories to tailor control logic for start/stop sequences and interlock configurations. This configuration is commonly used to control motors in applications such as conveyors, pumps, fans, and other equipment where remote motor control is required. The 208 V coil rating makes it well-suited for facilities powered from common three-phase 208 V supplies, and its robust construction supports frequent switching in demanding environments.
