Allen-Bradley 100-B110ND3 is a three-pole, non-reversing AC contactor from the Bulletin 100-B family, designed for reliable motor control in industrial panels. It is rated up to 110 A and supports line voltages up to 660 V, with a control coil rated for 100–127 V AC at 50/60 Hz (typical 110 V AC control supply). Common applications include switching three-phase motors and other AC loads such as pumps, fans, and conveyors in industrial automation, where a rugged, compact contactor is required.
