9065TR5.5 - Square D Thermal Overload Relay

9065TR5.5 - Square D Thermal Overload Relay

If you’re maintaining an existing motor control system, the Square D 9065TR5.5 thermal overload relay is the kind of component that helps keep equipment operating the way it should. Designed for 3-phase applications, this Class 9065 relay provides adjustable overload protection from 5.5A to 8.3A and is commonly used in motor starters, control panels, and industrial equipment where reliable protection is needed to help prevent motor overheating.

The open-style design keeps installation simple inside compatible assemblies, while the compact footprint works well in tighter panel layouts. This relay is frequently found in manufacturing facilities, HVAC systems, pump controls, and conveyor equipment where older Square D motor control components are still in service. For maintenance teams and electricians, having the correct overload relay matters — especially when matching existing equipment specifications and keeping downtime to a minimum. Like many Square D control components from this series, the 9065TR5.5 was built for long-term use in demanding industrial environments.
