Allen-Bradley 100-A09NJ3 Contactor With Overload Relay

Allen-Bradley 100-A09NJ3 Contactor with Overload Relay pairs a 3-pole IEC contactor with a 24 V coil and a Bulletin 193-BSB60 solid-state overload relay, delivering a rated 9 A switch current for three-phase loads and supporting motor protection up to 600 V across the load terminals. The 24 V coil aligns with standard automation control circuits, while the main contacts are rated for up to 600 VAC, making it suitable for a range of industrial motors and equipment. The included 193-BSB60 overload relay provides solid-state protection for motors in the 4–6 A category, helping prevent overheating and burnouts under overload or stall conditions. In 100-A09 devices, a normally open auxiliary contact is provided, sharing the same electrical ratings as the main power contacts, enabling simple interlocking, status signaling, or control circuit logic without adding a separate device. This compact starter is commonly used in light-to-medium duty motor control applications such as conveyors, pumps, fans, and machine tools where reliable interlock and overload protection are required, and it integrates neatly with other 100-series components for modular control panels or compact enclosures.
