Allen-Bradley 100-C16D400 Three-Phase Contactor

Allen-Bradley 100-C16D400 IEC Contactor is a compact, four-pole line-side switch designed to control three‑phase motors and other heavy loads with a rated load current of 16 A. It features screw-terminal wiring for reliable field connections and four normally open auxiliary contacts that provide flexible control and signaling alongside the main power path. The coil is rated for 120 VAC, enabling straightforward integration with standard control circuits, and the device belongs to the Bulletin 100-C family, offering a space-saving IEC design with consistent mounting and electrical characteristics for panel builders. Common applications include motor start/stop control in conveyors, pumps, fans, and other industrial equipment where reliable IEC contactors are required, with the ability to wire auxiliary contacts for interlocks, status indications, or remote signaling without altering the main power circuit.
