Overview
The Square D 9065 TE3.7 thermal overload relay is a NEMA-rated melting alloy protection device designed to safeguard three-phase motors from overload conditions. The TE3.7 thermal unit rating provides protection in the 3.0–3.7A range, making it ideal for small to mid-range motor applications in industrial starters and manual/magnetic control systems. As part of the Class 9065 overload relay platform, this unit is engineered for reliable trip performance and drop-in compatibility with legacy NEMA-sized starters.
