Allen-Bradley 100-A30NA3 AC Magnetic Contactor

The Allen-Bradley 100-A30NA3 AC Magnetic Contactor is a three-pole, 30-amp AC switch designed to control motors and other inductive loads in control panels and industrial equipment. This 100-series device includes three main contacts and a single normally open auxiliary contact, enabling simple signaling or interlock wiring in a compact, standard mounting footprint, with retailer listings identifying this exact model as a Series B variant of the 100-A30N family. The coil is rated for 220 VAC, making it compatible with many European and Asia-Pacific control circuits, and the model is commonly selected for conveyors, fans, pumps, and light-to-medium motor loads where reliable actuation and clean separation between control and power circuits are essential. Built to withstand frequent cycling in industrial environments, the 100-A30NA3 provides a compact, single-coil solution to control a three-pole motor starter with one NO auxiliary contact, and it can be wired to PLC outputs for straightforward on/off control of a motor or inductive load at 220 VAC coil voltage.
