Allen-Bradley 100-A38N3 Contactor 3-Phase 120V Coil

Allen-Bradley 100-A38N3 Contactor is a 3-pole motor starter with a 120 V AC control coil, designed to switch three-phase loads in industrial control panels. It carries a 38 A main current rating (Ie) and is commonly used to run motors up to about 25 HP in typical 460–480 V environments. This model sits in the 100-A family, a standard choice for general-purpose motor control in automation, pumps, fans, conveyors, and other equipment where reliable, four-wire switching of three-phase power is required. The 120 VAC coil makes it a straightforward drop-in for circuits that energize with standard line voltage, and its 3-pole configuration provides three main power paths in a single device. When integrating the 100-A38N3, ensure the coil voltage matches your control circuit and that the contact arrangement aligns with your schematic, so the starter interlocks and protective controls coordinate correctly with the motor load. For best results, reference panel wiring diagrams and verify that the mechanical mounting and terminal styles are compatible with your installation.
