9065TD8 - Square D Thermal Overload Relay Description
9065TD8 - Square D Thermal Overload Relay
The Square D 9065TD8 is a solid-state thermal overload relay from Schneider Electric’s trusted Motor Logic (Class 9065) platform. Designed for industrial-grade motor protection, it offers an adjustable trip range of 8–11.5 A and voltage ratings up to 660 VAC. Engineered as a modern replacement for traditional melting-alloy relays, the 9065TD8 provides fast, accurate, and ambient-insensitive performance, complete with phase-loss and phase-unbalance detection. Though discontinued by the OEM, TD8 units remain in stock through authorized suppliers with full testing and 2-year warranties.
