Allen-Bradley 100-C12D400 Three-Phase Contactor

Allen-Bradley 100-C12D400 is a compact IEC three-phase contactor from Rockwell Automation's Bulletin 100-C family, designed to switch motors in control panels. It uses a 110–120 VAC (50/60 Hz) control coil and line-side screw terminals for rugged wiring, with a 12 A load rating and four normally open auxiliary contacts to support signaling and interlocking without an extra relay. Rated for up to 600 V AC switching, it enables three-phase motor control across common industrial voltages. Horsepower ratings reflect typical motor sizes: 3 HP at 200–230 V, 7.5 HP at 460 V, and 10 HP at 575 V. This model is engineered to integrate with Bulletin 100-C series motor-control systems, providing a compact, dependable solution for panel builders and automation applications that require straightforward wiring, reliable actuation, and auxiliary contact capability in a single device.
