Allen-Bradley 100-A09N3 Three-Phase Contactor

Allen-Bradley 100-A09N3 is a three-pole contactor in the 100-A line, designed to switch three-phase power in industrial control panels. The 100-A09N3 designation identifies a specific three-pole configuration within Rockwell Automation’s 100-A family, a long-standing line of frame contactors used to control motors, conveyors, pumps, and other three-phase loads in manufacturing environments. The product is described as not obsolete, and it is listed as available for use with all bulletin 100-B frame contactors, signaling ongoing support and compatibility across the broader 100-frame ecosystem. This model provides a compact, modular solution that integrates with standard control circuitry and is designed for repeated energization and de-energization in automated systems. By sticking to the familiar 100-A design language, the 100-A09N3 helps maintain consistency with existing installations and simplifies part sourcing for retrofits and replacements across facilities that rely on Allen-Bradley motor-control components.
