Allen-Bradley 800T-24JWH5KB7AA Thermal Overload Relay

The Allen-Bradley 800T-24JWH5KB7AA Thermal Overload Relay is a component in Rockwell Automation's 800T family designed to protect motors in industrial control panels by monitoring operating current and providing a defined trip signal to the connected contactor or drive when an overload is detected. It is intended for use with Allen-Bradley contactors and packaged drive assemblies, and includes an OL1 overload-trip contact along with a motor fault pilot light that illuminates to indicate when an overload condition has triggered a trip. The 800T-24JWH5KB7AA configuration identifies a specific device within the 800T line, suitable for integration into motor protection schemes in motor control centers, automated workcells, and packaged-drive configurations where rapid fault visibility and interlock protection are required. In practice, this relay supports predictable, local diagnostic feedback by signaling the motor fault condition, enabling maintenance teams to verify protections and respond to overload events while helping prevent motor damage.
