Allen-Bradley 100-C12D10 Electrical Contactor

Allen-Bradley 100-C12D10 is a 3-pole IEC power contactor with a 110/120 VAC coil and a single normally open auxiliary contact, intended for motor control and general-purpose AC switching in control panels. The device provides three main power contacts to switch three-phase loads while offering one NO auxiliary contact for control signaling or interlocking. Rated for 12 A under AC-3 service, it handles typical motor-start and other AC loads within industrial automation applications when paired with appropriate overload protection and wiring. Wiring is accomplished via screw terminals, and the unit is designed for DIN-rail mounting for compact panel installations. As part of Allen-Bradley’s 100-C family, the 100-C12D10 aligns with standard mounting patterns and coil voltages, making it straightforward to substitute or expand existing control circuits without changing the panel hardware. Typical applications include motor control for fans, pumps, conveyors, and other 3-phase equipment in manufacturing and process environments.
