Allen-Bradley 100-A12NZJ3 is a three-pole, general-purpose AC contactor designed to switch 3‑phase loads in industrial control circuits. It provides a 12 A main circuit rating at up to 600 VAC and is operated by a 24 V DC coil, enabling reliable control from standard low‑voltage equipment. The unit includes one normally open auxiliary contact (1NO) to support signaling or interlock functions within the control circuit. As a Series B member of the 100‑A family, the 100-A12NZJ3 is commonly used for motor control and other 3‑phase applications where compact, rugged performance is required.
