Allen-Bradley 100-C12D10 3-Phase Contactor Relay

Allen-Bradley 100-C12D10 is a 3-pole IEC contactor from the Bulletin 100-C family, engineered to reliably switch three-phase motors in industrial control panels. It features line-side screw terminals and a single normally open auxiliary contact, all in a compact, rugged package designed for AC-3 duty. The coil is 110 V AC (50/60 Hz), with a 120 V version available for 60 Hz systems, enabling broad electrical compatibility across regional power standards. Rated for 12 A on AC-3 service, it accommodates motor loads up to roughly 3 HP at 200–230 V, 7.5 HP at 460 V, and 10 HP at 575 V, depending on your supply voltage. The 100-C12D10 is well-suited for applications such as conveyors, pumps, and fans where a reliable, field-replaceable contactor is needed to control a three-phase motor, and the included 1 N.O auxiliary contact supports signaling or interlocking within the same device footprint.
