Allen-Bradley 100-A38ND3 Programmable Logic Controller Module

Allen-Bradley 100-A38ND3 is a 3-pole contactor from Rockwell Automation used to switch three-phase loads in control panels and industrial equipment. It operates on a 110/120 V AC coil at 50/60 Hz and is rated for up to 38 A, providing reliable motor control in a compact enclosure. The unit includes one normally open auxiliary contact and is identified as Series C, facilitating straightforward integration into standard control schematics. This contactor is designed for use in control circuits such as conveyors, pumps, and fans where a robust on/off switch for a three-phase load is required. The 100-A38ND3 is a discontinued model, yet it remains common in spare parts inventories and legacy installations, where replacement parts or service documentation reference its 3-pole, 110/120 V AC coil configuration and 38 A load current rating.
