The Schneider Electric Thermal Overload Relay (16–24 A) is engineered for reliable motor protection in demanding industrial and commercial applications. Designed to IEC, UL, and CSA standards, this Class 10A relay safeguards motors against overload and phase failure conditions — making it a trusted choice for panel builders, electrical contractors, and maintenance professionals across Canada. With a wide adjustment range of 16–24 A, temperature compensation from -20 to 60 °C, and mercury-free construction, it delivers consistent, code-compliant performance whether mounted under a contactor, on a DIN rail, or on a plate. The red stop and blue reset push-buttons provide intuitive on-site control, while screw clamp terminals ensure fast, secure wiring on the job site.
