Allen-Bradley 100-A12ND3 AC Magnetic Contactor

Allen-Bradley 100-A12ND3 is a three-pole IEC non-reversing AC magnetic contactor in the Bulletin 100 series, rated for 12 A at up to 600 V (AC) and designed for motor control in 3-phase circuits. It uses a 110–120 V AC coil for 50/60 Hz operation and includes one normally open auxiliary contact; the unit is DIN-rail mountable and compatible with Bulletin 100 motor control systems. Horsepower ratings at common voltages include 3 HP at 200 V and 230 V, 7.5 HP at 460 V, and 10 HP at 575 V, making it suitable for sizing start/stop control of medium-sized three-phase motors. This contactor is intended for use in industrial control panels and other applications requiring compact, reliable switching of 3-phase loads up to 600 V and 12 A.
