Allen-Bradley 100-C12D10 Three-Phase Contactor

Allen-Bradley 100-C12D10 is a 3-pole IEC contactor built for reliable three‑phase motor control. This Bulletin 100‑C device uses line-side screw terminals and is rated for 12 A (AC‑1) with a single normally open auxiliary contact for signaling or interlocking in control circuits. The coil is specified for 110 V AC at 50 Hz or 120 V AC at 60 Hz, allowing regional voltage compatibility without changing the unit. In practical terms, the 100-C12D10 can switch motors rated around 3 HP at 230 V, 7.5 HP at 460 V, or 10 HP at 575 V, depending on supply voltage. Designed to be compact and modular, it integrates with the 100‑C family’s control accessories, enabling easy expansion with additional auxiliaries or interlocks as needed.
