Allen-Bradley X-33547 Overload Relay

Allen-Bradley X-33547 Overload Relay is a motor-protection device designed for use with compatible Allen-Bradley contactors in industrial motor-control panels. Identified by the X-33547 part number, this relay is part of Allen-Bradley’s overload-relay family manufactured by Rockwell Automation. It provides overload protection by monitoring current in the motor circuit and triggering a trip when preset thresholds are exceeded, helping prevent motor damage and reduce unplanned downtime. Common applications include pumps, fans, conveyors, and machine tools where reliable protection of electric motors is essential. The relay is intended to be wired as part of a motor starter assembly, pairing with the corresponding contactor and safety devices according to standard Allen-Bradley installation practices. For exact specifications such as current range, trip class, mounting dimensions, and compatible starter configurations, consult Rockwell Automation's official product documentation or trusted distributors for this part. In typical industrial settings, overload relays like the X-33547 work alongside contactors in centralized control panels to guard motor-driven equipment and support preventive maintenance strategies. As an Allen-Bradley product, it aligns with Rockwell Automation’s ecosystem of motor-control components, facilitating maintenance, stockkeeping, and potential interchange with other compatible relays in the same family.
