Allen-Bradley 100-A09NZ3 Motor Starter Overload

Allen-Bradley 100-A09NZ3 Motor Starter Overload is a three-pole motor starter that pairs a Bulletin 100 contactor with an integral overload relay (193-BSB16) to provide switching and thermal protection for small three-phase motors in a single, space-saving package. The unit is coded for a 9 A load and incorporates the 193-BSB16 Series B bi-metallic overload relay, which features a 1.0–1.6 A trip range and a manual reset to restore operation after an overcurrent event. Designed for industrial control panels, it simplifies wiring by combining control, switching, and protection in one device, making it suitable for conveyors, pumps, fans, and other small machines where reliable motor protection and quick control are essential. As a genuine Allen-Bradley component pairing, it ensures compatibility with standard 100-series contactors and readily available replacement parts, making it a predictable choice in OEM installations and service environments that rely on Rockwell Automation hardware.
