Thermal Overload Relay is a professional motor protection component with overload protection, temperature sensitivity and adjustable control as core advantages, widely used in motor control panels and industrial control systems. It adopts bimetallic strip temperature‑sensitive components to continuously monitor circuit current and temperature, accurately detect overcurrent and overheat faults, and automatically disconnect the circuit under overload conditions to effectively avoid motor burnout and equipment damage. The product supports adjustable sensitivity and trip points with a wide current adjustment range, can be matched with different motor requirements, and supports manual reset after fault elimination to quickly restore normal operation. Featuring easy installation and strong compatibility, it can be used with contactors to form a complete protection system, providing safe, stable and long‑lasting thermal protection for motors. With reliable performance and compact structure, it is an ideal choice for industrial motor overload protection, effectively improving operation safety and service life of electrical equipment.
