HCET bimetallic overload protector is based on the principle of thermal deformation of bimetallic sheet, and senses the temperature change of the equipment through the precision calibrated bimetallic element. When the temperature exceeds the preset threshold due to abnormal circuit current, the bimetal bending by heat triggers the mechanical linkage device to quickly cut off the power supply within 4-10 seconds; the temperature is automatically reset after it returns to normal, without manual intervention. Specifically designed for motors, compressors, transformers and other equipment, can effectively prevent overload, short-circuit winding burnout accidents, suitable for -30 ℃ to 250 ℃ wide temperature range of working environment.
