Allen-Bradley 100-C23ZS400 Direct Current Contactor

Allen-Bradley 100-C23ZS400 is a four-pole direct current contactor from Rockwell Automation’s Bulletin 100-C family, configured for a 125 V DC control coil and intended to switch DC loads in industrial control panels. It uses four main power poles and a 125 V DC coil, and is compatible with standard 100-C accessories such as auxiliary contact blocks and interlocks. As a member of the 100-C family, the 100-C23ZS400 shares mounting, wiring, and accessory interfaces with other 100-C/104-C devices, which can streamline panel layout and future upgrades. Typical applications include DC motor control, conveyors, pumps, and other automation loads in manufacturing or process environments where DC switching is required. This variant represents the DC-operated option within the 100-C line, designed for compact installation in control enclosures while providing consistent operation in routine industrial switching tasks.
